Lhtech-800 was the starting point of the engine.
According to TEI’s site, it has 2 stage radial compressor, reverse flow combustion chamber, 2 stage axial HP turbine section and a 2 stage axial power turbine.

I suppose it (TF-6000) would need something like this in evolving the TEI-1400 core (summarising a lot):

A) CFHP-1 (1st radial) stage to be turned into a ~ 4 stage axial LP one (adds weight and length) for better (turbofan) flow efficiency.

Shares shaft with likely new 3 stage LP turbine (that replace 2-stage power turbine there currently that drives the output shaft currently).



B) Keep CFHP-2 (2nd radial) as is. Most turbofans in this thrust class keep a radial HP stage for compactness balancing with (A).

Shares shaft with the 2 HP Turbine stages currently there (which you can keep as is).



C) Fan stage added.

Shares shaft with (A) i.e driven by LP turbine. Adds some length and lot of weight (esp when including bypass design).



D) Combustor needs to be made straight-through (conventional) instead of reverse.

This allow for optimal bypass flow by reducing/smoothening diameter of core in this section (which reverse combustor increases to save length for TS/TP where bypass consideration does not exist). Obviously adds length....adds some weight by casing/nacelle extension to accommodate.


===========================

So basically some of the core (part B) can be kept as is (just needs some lengthening of spool shaft given D).

A complete redesign is likely not needed as basically (an elongated) HP spool is kept same (retaining proven process flows and saving RnD feedback loop here)

You can get 6000 lbf dry out of this with the relevant RnD that is needed (A, C, D and other stuff I'm leaving out from the summary).

Maybe even higher than that. Maybe lower depending on how the various realised process flow considerations are within TEI that I cannot comment on. Either way would be interesting to see how the TF-6000 project goes.

Reheat analysis would add some more 1000's of lbf to get to 10,000 etc if you need that.
But I wouldn't really see need for it at this thrust class for UAV etc....given the lack of need (IMO) and weight and fuel cost buffer imposed.

In any case a solid 6000 lbf turbofan would add a huge capability to Turkey...particularly its UAV ecosystem (esp stealth drones).

BTW if needed, mods can move (or copy) the relevant posts in this thread's last few pages etc (that are more engine-talk based) to TR propulsion thread or similar....

Probably is not a cheap radar. So only 8 Aesa radars for the 24 TB2s will be used.

Polonya tarafından her birinde 6 adet SİHA bulunan 4 setlik TB2 SİHA alımı (toplamda 24 adet) yapılacak. Her bir sette;

  • 3 adet Baykar Mobil Yer Kontrol İstasyonu (Mobil YKİ)
  • 6 adet MX-15 EO/IR Sensör
  • 2 adet Leonardo Osprey 30 AESA radar
  • 6 adet IFF sistemi
  • 3 adet mobil veri terminali (menzil uzatma amaçlı) yer alacak.

It will improve the effectiveness of the UAV immensely. But personally I still would like to see, as an interim solution, until our Aesa based SAR is operational, Meteksan’s MILSAR UAV/SAR GMTI radar on our UAVs. Over the clouds operation capability with 27km range is a big plus and is not to be sneered at.
OK, laser targeting will not work over clouds. But ground assets can take over for that. Or other ammo can be used. Albeit these are all extra weights, that detract from platform’s usable weight carrying performance.

2 radars per set. This radar can be scaled up to 4 antennas can be used simultaneously on same aircraft. We don't know about the details of how they will mount it. Maybe they are planning 2 radar antennas per aircraft. Each under a wing giving 240 degrees coverage.

A few news on some systems to be in service within 2021, tethered jammer drone is one of them, in addition to KARAGOZ - TEPEGOZ and multi-rotor survailance gangs:

(Translated directly in Google, please correct if anything is absurd)

ASELSAN UNMANNED AIRCRAFT FAMILY​


SAKA MICRO UNMANNED AERIAL VEHICLE


SAKA Micro Unmanned Aerial Vehicle Project is an Unmanned Aerial Vehicle (UAV) development project that can be easily transported, can be integrated with land platforms, and can perform indoor and outdoor missions for reconnaissance, surveillance and intelligence purposes.


During the development, the aircraft platform design was updated and brought closer to the final product configuration, depending on the sub-units used, the structural analyzes performed and the new functions added.


Within the scope of the project, activities are carried out with two different aircraft configurations, SAKA-1 (650 grams) and SAKA-2 (950 grams).


SAKA1_8468.png



SAKA-1 Aircraft System


At this stage, integration studies have been completed for SAKA-1 and SAKA-2, which include the original aircraft platform, propulsion system, foldable arms and replaceable battery, compact aircraft platform and flight controller hardware, software and algorithms, and flight tests have been carried out successfully.


Sub-systems are being nationalized, and it is aimed to nationalize the data link system and image processing unit together with the original flight controller, to reduce foreign dependency and to realize product capabilities with lighter and smaller aircraft platforms.


Within the scope of armored vehicle and Unmanned Ground Vehicle projects carried out by ASELSAN, activities for the system integration of small-sized aircraft, which are needed to monitor the departure routes of land vehicles from certain distances, have also been initiated. Work has begun on the design of a mechanism that can meet this need, be integrated into different land platforms, and enable the aircraft to take off automatically without the need for manual intervention.


With the nationalization of the Ground Control Station Software and Data Link System, the authenticity and locality rate of the SAKA system will increase.


Motion detection, target tracking, etc. Development efforts are also underway to enable the aircraft to perform image-based missions in closed spaces, independently of GNSS signals.


With a minimum flight time of 25 minutes, a data and image transmission range of 3 km, a unique flight controller and ground control station software infrastructure that can be customized according to needs, and a communication system with a swarm infrastructure that is resistant to electronic warfare threats, it is planned to outperform foreign-origin products.


By the end of 2021, it is aimed to implement the original, domestic and national SAKA Unmanned Aerial Vehicle, weighing less than 500 grams, with flight controller and image processing unit hardware and software, data link system and various autonomy capabilities for the first time in our country.





KARAGÖZ BALLOON SURVEILLANCE FAMILY


In the field of ASELSAN unmanned systems, it is aimed to develop remotely controlled unmanned vehicles that will be widely used in the battlefield of the future and have the ability to decide and implement on their own.


After the development of the KAŞİF Balloon Surveillance System, 35 m3 stable curtain airborne balloon aircraft were produced with domestic industry facilities, with the aim of gaining reconnaissance/surveillance and early warning capabilities with the close safety of fixed facilities such as small units and police stations, and with the MINI GIMBAL Payload Gaziantep-Kilis A field demonstration was held for the end user for approximately 400 hours at a designated police station in .


After the field trials, improvements were made to the system in line with the opinions received from the end user, and 72 m3 Balloon Aircraft was produced and the ATMACA Payload was shown to the Special Forces Command between 31 October - 03 November 2016.


Participation in the Efes Combined Actual Shooting Exercise (İzmir-Seferihisar) organized by the Turkish Armed Forces on an international scale for the first time. The drill was viewed from beginning to end and appreciated by the water drop-shaped balloon aircraft and the ŞAHİNGÖZÜ OD camera mounted on the stabilized Pan-Tilt.


In 2016, a demonstration was held with the participation of representatives of the Navy, Coast Guard, Land Forces, Gendarmerie, Prime Ministry and SSB. After this mission, they prepared an evaluation report from all forces stating their needs.

The KARAGÖZGAG System, designed as wired in line with the need for 365 days/24 hours surveillance of a wide area from high altitude in the border region, is integrated into the nationally produced balloon aircraft by ensuring the communication of ATMACA and GAG (Large Area Surveillance) payloads with each other, to the fixed military units. It has been developed for the purpose of gaining intelligence information and early warning capability. The shape and size of the KARAGÖZGAG System are determined according to the project by obtaining various parameters (position, altitude, temperature, payload weight) in accordance with the concept.


After the KARAGÖZ-GAG System Adoption to be made to the Turkish Armed Forces (TAF) in 2021, it is envisaged that the KARAGÖZ-GAG System will be widespread in the border regions.


ARI-1T ROTARY WING MINI UNMANNED AERIAL VEHICLE


ARI-1T Rotary Wing Mini Unmanned Aerial Vehicle can serve military and civilian areas.


With a communication range of 15 km, an altitude of 10,000 ft and a flight time of 2 hours, ARI-1T can autonomously perform the mission plan defined before and during the flight. Thanks to its wide area scanning and real-time target identification and determination feature, it meets many needs such as rapid operation capability, mobile base station mission, instant intelligence information in situations such as enemy element identification and disaster management.


ARI-1T can provide opportunities for many types of military operations thanks to its vertical landing and take-off compared to fixed wing UAVs, no need for a long runway, its ability to hang in the air and high maneuverability, and it plays an important role in meeting civilian needs by being equipped with different payloads.


ARI_1824.jpg
ARI-1T Rotary Wing Mini UAV will reduce the need for operations, especially in coastal waters, with its ability to land, take off and track the ship, except for land activities. It offers a deep and wide infrastructure for the solution of different needs. The live transmission of the REYK (shot hit) information to the command center with the ARI-1T System in surface and land bombardments was carried out successfully in various exercises.


With the ARI-1T Rotary Wing Mini UAV, the Dronecell platform is being developed to provide communication support to search and rescue teams in natural disasters such as earthquakes, floods and landslides, as well as military use. Work continues on the integration of the mobile/flying base station developed by Turkcell into the ARI-1T System in order to serve in such situations where mobile access is limited.


SERÇE MULTI ROTOR UAV SYSTEM


The SERÇE System is an unmanned flying system that can be equipped with different payload kits according to mission needs such as reconnaissance, surveillance and intelligence missions, road traffic information and border security, and can perform fully autonomous missions.


The SERÇE-1 and SERÇE-2 Multi-Rotor UAV Systems, which are found in high quantities in the TAF and Security Forces inventories, with various projects initiated and carried out under the leadership of the SSB, are actively used all over the country, and border surveillance and Modular Temporary Base Area (MGUB) Projects. It is also used effectively for border security.


432523432532652423_2333.JPG



The adventure started with the SERÇE-1 System, which can stay in the air for 30 minutes and has a communication range of 5 km, in line with the changing technologies and operational demands from the field; The SERÇE-2 system has emerged by adding various algorithms developed and improvement studies carried out. The SERÇE-2 System, on the other hand, can function autonomously by defining a mission plan before or during the flight, with a flight time of 60 minutes at sea level.


In addition, in the SERÇE-2 System; Joystick integration capability has been gained, the noise level of the system has been reduced, the size of the bag has been reduced according to operational needs, and a modular structure allowing easy installation in the field has been adopted.


In addition to all these studies, SERÇE Systems' explosive (Mine/IED) detection and destruction capability for the needs of METI teams to be used in various operational usage scenarios, Fire Support Automation System (ADOP) Integration, integration into the ASELSAN Cenker system, which is the common platform for integrated warfare capabilities. studies are carried out.


Our ASELSAN engineers, working to bring the developing technologies to the use of the field, focused on the use of UAVs in the mixing environment, which has become one of the biggest needs of the field, and carried out different studies to reduce the possibility of accident / massacre and falling into the hands of enemy elements as much as possible. In addition to the communication link and GNSS solutions that are more resistant to interference with the newly released SERÇE-3 System, studies on image processing-based solutions are continuing. In the SERÇE-3 System, the communication range of which has been increased to a minimum of 10 km; By adding an imaging system with precision stabilization, the image quality has been greatly increased and restricted area detection, moving target detection and tracking, 3D map application,Algorithms such as mission change in the air that enable the simultaneous use of more than one aircraft have been added to the system.


For the conscious and effective use of SERÇE, we always aim to support our users with training activities carried out both in ASELSAN and in the field.


The Sparrow System continues to serve outside of military use as well. By participating in forest fire response support activities, wide area scanning from the air, measurement of underground high temperatures with a thermal camera at night conditions and directing the relevant units to the specified coordinates are ensured.


STRIKE MULTI ROTOR UAV SYSTEM


When the information and studies on Unmanned Aerial Vehicles used for reconnaissance and surveillance in various armies around the world are examined, it is seen that the potential of unmanned vehicles to neutralize the targets determined after the observation, in addition to the observation purpose, has begun to be used.


In this context, with the Striking Multi-Rotor UAV System being developed by ASELSAN engineers, it is aimed to neutralize the targets, where the user enters the target/coordinate information or the targets determined by taking real-time images as a result of reconnaissance/surveillance, with the warhead detonation integrated into the Multi-Rotor Unmanned Aerial Vehicle.


Within the scope of the project carried out together with ROKETSAN, studies are carried out to develop a Striking Multi-Rotor UAV platform with a total weight of approximately 15 kg to carry approximately 3.5 kg of ammunition with different warheads.


It is evaluated that the developed Striking UAV can be used by our security forces in conditions required by the survival of the country, especially in the fight against terrorism.


TEPEGOZ CABLE MULTI ROTOR UAV PROJECTS


Since 2017, cable UAV development studies have been carried on. The studies that started with the concept presentation and mutual cooperation agreement at IDEF 2017 gained momentum with the opening of the R&D project in 2019.


Participation in the EFES 2018 Exercise was ensured with two systems. Within the scope of this exercise, more than fifty flights were carried out in 11 scenarios. Four aircraft and two ground stations were also invited for the EFES 2020 Exercise, but no participation was ensured as the exercise was cancelled.


TEPEGÖZ R&D Project


It is a surveillance system development project consisting of a multi-rotor Unmanned Aerial Vehicle with a cable and an integrated ground station system, which can operate under link interference, provide long-term surveillance, transmit power and data from a special cable, in order to protect critical facilities and forward base areas. Integrated day/thermal camera with three axis stabilized gimbal is carried as payload.


THS 6 maturity level has been reached with the participation of many flight demonstrations, conferences and exercises. The project is planned to be completed in 2021.


Ground and flight tests have been carried out so far, a total of 130+ flights have been reached, and a 4-hour ground test has been successfully carried out under challenging conditions. The project flight altitude target was achieved by performing a test flight at 103 meters AGL altitude.


Link Jamming Resistant Wired Surveillance System


It is the development of a wired surveillance system that can function within certain limits under link jamming. The ultimate goal of success and performance parameters is to show that the system, which can perform surveillance at 100 meters altitude with EO/IR payload, detect and report moving targets, can perform its duties in practice under RF link jamming.


Automatic Tension Controlled Crane System


The automatic tension-controlled winch system, which calculates the cable tension by measuring the cable tension by means of the sensors on it and reacts accordingly, keeping the cable length at the desired amount, is not currently available in the domestic market. The goal of success and performance parameters is to perform the winding and laying of the cable without interfering with the operation of the aircraft in the altitude range of 0-100 meters.


Mobile Robotic Ground Station


In cases where the system will operate alone and will not be integrated into a vehicle, it will minimize the transportation requirements of the personnel, contain all the necessary components, host the aircraft and ground components, use solar panels (OPS), batteries and utility power sources, including emergency situations. It is a system that can easily be transferred to the task area when it is unloaded from the main vehicle, thanks to its electrical drive.


Precision Landing Capability (GTSDS)


A deep learning and image processing based navigation support system (GTSDS) is being developed for the system to perform take-off, landing and navigation even without GNSS.


TEPEGÖZ-JEMUS Project


TEPEGÖZ R&D Project is a project in which activities are carried out to operate at higher altitudes and with different payloads, using the engineering basis. A contract was signed between SSB and ASELSAN on March 30, 2020 for the need for a 7-system Wired Drone within the scope of the JEMUS 8 (5 Provinces) Project. 150 meters AGL height, expanding the coverage area of the E-Type Mobile Repeater Radio (RELAY) payload to be provided by HBT, making communication uninterrupted and mobile, high altitude/heavy load/light, suitable for transportation and installation with personnel, modular system/high altitude and long tenure requirements are targeted.


Within the scope of the JEMUS-8 5 Provinces Agreement, it is aimed to complete the installations of the provinces of Siirt, Bitlis, Van, Şırnak and Hakkari.



SHAR UAV R&D PROJECT


The ability to serve as a swarm has become a needed feature for UAVs today. The application of this feature, which is also common in nature, to UAV systems will enable more than one UAV to be managed easily and to perform tasks more effectively. It shows that while the size and costs of unmanned vehicles are decreasing as a result of technological developments, their capabilities and numbers will gradually increase. The use of swarm UAVs will be reflected on the battlefield as a force multiplier.


ASELSAN has been carrying out development and technology building blocks for the herd concept since 2009. One of the most important of these studies is the Technology Acquisition Obligation (TQM) SQUAD UAV Project, which was carried out between 2017-2019 within the scope of the protocol signed with the Presidency of Defense Industries. ASELSAN MGEO Sector Presidency, Atılım University, METU and ITU took part in this project and it was successfully completed. It is aimed to create the necessary technological infrastructure for the domestic development of the control and coordination algorithms of the herd UAV systems, which the Turkish Armed Forces started to need.


A HERD UAV R&D project was initiated, based on the swarm algorithms and capabilities used within the scope of TQM, but aiming to implement it on Multi-Rotor Platforms with Distributed Herd Management Technology using a different architecture. The R&D project of the SERİ UAV, which was initiated in 2018, is targeted to be completed in 2021.


The project will pave the way for the TAF, which is gradually adding single unmanned vehicles to its inventory, to coordinate these vehicles as a herd with an add-on, and will make great contributions in terms of both time and cost. Thanks to the modular development of the swarm plugin and algorithms to be developed, it will be possible to use them on different unmanned platforms, including air, land and sea.


456348743_1166.JPG



It will be possible to increase mission effectiveness and efficiency, expand the scope of duty and provide more effective surveillance by using the task sharing and vehicle switching capabilities with the UAVs acting in a coordinated way in swarms.


The products and capabilities developed within the scope of the project will be integrated with multi-rotor UAVs, and test and flight demonstrations will be performed with many UAVs.


In this context, the developed swarm algorithms can be applied to homogeneous or heterogeneous unmanned systems (air, land and sea). Especially low-cost Kamikaze UAVs attacking in the form of swarms will increase the effectiveness of the strike. With the ammunition or payload to be added to the UAVs acting in a coordinated swarm, the destruction of the targets and the efficiency of the logistic support activities will be increased when necessary. It can be used as a force multiplier in the operation area with different mission scenarios.
