İt is further than rotary engine however the main disadvantage of rotary engines is lifespan. But they solved it.
( Noisy?? İ wouldn't say it)

This engine will be US Army's future generator!!!



@Yasar could it be Also generator for electric ALTAY MBT?
Wankel/Rotary engines are theoretically how all combustion engines should be designed as.
One single motion direction. No sudden repetitive jolts and kicks which are part of a cylinder/piston engine.
If you listen to the Mazda rotary engine it sounds like an electric engine.
But in real life so much development and technology and money and time has been spent on conventional cylinders/piston engines that the rotary engine never actually took off and replaced its brethren. Similar case is with supercharger (which takes its power directly from driveshaft eliminating lag) and turbocharger (which takes its power from exhaust gas emissions giving lag problems) . Although theoretically and technically superior, supercharger never really managed to beat the success of a turbocharger.

It is one thing to produce a small engine, and totally another story to make a larger version of it and be successful. But looking at the basics of this technology it is innovative and could well be groundbreaking if it can be developed properly. There is nothing stopping it from becoming a new combustion engine line that can double up as a generator too.
But as it is, it is early days and it doesn’t really develop enough power to charge batteries that can drive a heavy military armoured vehicle, yet. Nevertheless there are basis for being optimistic that it can be a very successful engine type if the claims of its power to weight ratios can be sustained in larger models.

But looking at the workings of the current Wankel engine and the liquid-piston’s rotary engine, there is a lot to be optimistic about this new innovative tech.

They've probably blew all their capital on this single cartoonish example in the hope of getting a contract from the Greek government. 😂
I meam, look at tis thing! How can anybody take it seriously?
And it doesn't even make sense. I mean, 40 mm grenade launcher? Those things barely have 1 km of range 😁

Electronic CounterMeasures (ECM)​


ECM is the active part of EW and is intended to disrupt the surveillance systems of the enemy, whether by radar or radio communications, and also to counter any of his weapons which use electromagnetic, infrared or laser systems for guidance or aiming. There are two main methods of achieving this: by jamming, or by the use of decoys, both of which are effective when used properly. Many modern ECM equipment, particularly in the naval scenario, employ both methods in an integrated system.

Noise jamming is the use of transmissions to disrupt the enemy’s communications channels or to saturate his radar to obscure its target. Although this denies the enemy his information channels it also means that the jamming source cannot read the signals for intelligence purposes. Apart from this, modern frequency-agile communication systems are no longer easy to jam effectively.

Simple noise jamming is still in widespread use in the land warfare scenario, one important application being in remotely operated expendable jammers. These can be hand-emplaced, artillery-delivered, dropped from aircraft or used in unmanned aerial vehicles, and serve as short term jammers for a particular operation.

Electronic Counter-CounterMeasures (ECCM)​


Electronic Counter-CounterMeasures (ECCM) is the method by which you endeavor to combat the ECM systems of the enemy by either making your equipment ECM-resistant or by using techniques to nullify his jamming and/or decoy systems. It is an extremely sensitive area in that any disclosure of ECCM measures designed into a system is likely to inform the enemy of its vulnerability to ECM.

Against jamming systems, the most commonly used method is frequency agility, whereby the transmissions are made to “hop” over a large frequency band in a random fashion. This means that either the jammer has to spread its power over the entire band with the inevitable loss of strength on any particular frequency, or it must attempt to follow the signal as it hops randomly.

The latest technique is the use of “stealth” techniques to combat the radar system. This is beginning to be employed in aircraft and consists of several methods to reduce the radar cross section of the aim. The main techniques employed are

  • to design the airframe itself to avoid sharp corners and flat surfaces which act as radar reflectors, and
  • the use of radar-absorbent material which minimizes the amount of energy reflected back to the radar.
At the aircraft, the most important parts of the fuselage can be covered in radar-absorbent material to make it extremely difficult to detect.

Many anti-radiation missiles have been developed. The missile is passive in operation so that it cannot be picked up by ESM systems, and normally locks on to the sidelobes of the radar transmission. The main countermeasures against this type of missile are low sidelobes, frequency agility, and the use of decoy transmitters which must be positioned close enough to the surveillance radar to “seduce” the missile but not so close as to endanger the main system.


This is entirely a race between ECM and ECCM techniques. Kamikaze UAVs will one day have to be redesigned in accordance with invisibility technology and will target low observability. To ensure low RCS (radar cross section) values, we will see many changes such as material engineering (the widespread use of materials that absorb radar waves), designing the form of kamikaze UAVs accordingly, electrification of propulsion systems or the use of hybrid systems, etc. The future of anti-radiation kamikaze drones with a range of 50-60 km, also operating in passive mode, looks bright.

After the progress of countermeasure systems on the basis of both soft kill and hard kill systems, systems produced for simple but daily needs will be doomed to failure.
Therefore, it is unsustainable that today the costs for FPV kamikaze drones are in the range of a few hundred dollars. Because as the specificity of the applied technology increases, the unit cost will also increase. Therefore, projections that aim solely at quantitative density cannot have a future. Systems that can work effectively can only be projects that look for pinpoint vulnerabilities in target platforms and successfully close their own vulnerabilities against enemy countermeasure systems. This is only possible through specialization.

USSOCOM RFI- Counter-Electronic Countermeasure Seeker​

The USSOCOM Directorate of Science and Technology has issued a Request for Information (RFI) for the Next Generation Effects Capability Focus Area (NGECFA), specifically focusing on the Counter-Electronic Countermeasure Seeker (CECMS).
USSOCOM seeks to develop the ability to detect, identify, and target electronic warfare emitting systems that target GPS, command data link, communications frequencies, and counter-battery radars. Size, weight, power, data interface must make it suitable and effective when integrated on Class I & II UAS, as an additional sensor on larger ISR platforms, or the seeker on small, guided munitions.

What I wrote a few days ago was already among the research and development targets of US special forces.

In fact, the issue here is about transforming the problem for which I laid the foundation, from being a problem into an opportunity itself. The USA wants to see UAVs as a new springboard for SIGINT.

I pointed out one of the most fundamental issues of our day.
Engineering issues are a bit like this. By solving fundamental problems, you also lay the foundation for extraordinary projections.
Of course, high-level projections also require being visionary.

I really Wonder how high this drone can operate with something like 4 mam l bombs. If it reaches around 30 to 35kft, then it is very well done with the Tei engine.
Probably current pd170 is in use due to ongoing developments in pd222 which has much higher take of power which would allow tb3 to take off from tcg Anadolu with some payload perhaps.

We have no clue how much power the TB3 needs to take off from the Anadolu but if it lacks power some cable tug assist will work wonders. A more powerful engine if the TB3 ever needs one will rid the assist cables but is not absolutely necessary.

Mojave's MTOW is 3000 kg(2 times the TB3's) and its engine produces 450 hp(2 times the power output of PD222, 2x225hp). If we assume the requirements are changing linearly for small differences then PD222 makes more sense. It's oversimplified but gives the ballpark.

The TB3 is expected to join the Navy ranks in a month but is it like the TB3 will be deployed earlier then expected, I don't think so. It still needs to learn to land on Anadolu nicely before it can be fully operational on the ship. But the earlier the delivery the earlier the Navy will familiarize itself with the plane and be prepared for deployment. I think the TB3 can be used for ISR duties initially and after that it can be launched from the ship but would land on land based airstrips. In this way when you can deploy 10 TB3 on the ship you get a chance of 10 sorties to targets with full payload during an expedition. This will give the navy a taste of what TB3 will bring before it is fully deployed on the ship.

We may also check Mojave's operational range chart. (Given with respect to payload and take off distance-limiting fuel payload). In the STOL mode it gets 4 to 6 hours of ISR capability, unarmed.

It was going to be PD180 but likely they (Navy) noticed it doesn't worth the +8HP continous and -4 kg for -15HP @30k feet. PD180 is a nice engine but didn't fit this, has a great export potential nonetheless.

Same applies for PD222ST, +1kg, -15HP @30k feet but +50HP @ take off and +30HP @ continous @ 20k feet. Suits for STOL but not high altitude operations.

(Numbers given with respect to PD170DT's specs).

Looks like PD180 was omitted with the given weight figures and it was found more logical to apply pressure on Baykar to reduce weight of the platform (which they did, greater than what PD180 has provided).

I am assured there will be PD222ST variant on TB3 and there will be two kinds of TB3 on Anadolu. One for ISR @30k, another for strike at @20-25k feet. If there happens to be a PD222/5DT then these two platforms may be commonized. But TEI is busy with projects and may not be able to spare enough time for the certification processes of all programs. So i assume in mid term we will have mix of PD170/222, starting with PD170.

Based on Navy's habit of commonization we may also see TB-2 being handed over to another operator, or a friendly country and all replaced with Land based TB3.

what about the PD300 ? what platform is it for ?

View attachment 63141
PD300 is a little on the weak side for Akıncı and on the strong side for Aksungur. There seems to be no existing platform that this new engine is made to perfectly match. It is more of a project to take the PD170 to the extremes I guess. There is not really any information about it. However a new platform should be made to make use of this engine's full capability. If it is light enough which seems to be so it can even be used for VTOL aircarft. Like helicopters and compound helicopters that have both helicopter and plane features. Also civilian sector should catch up to use such engines. Some companies had seaplane development work in the past.

EDIT: I have just noticed that the PD300's full name is TEI-PD300H, with the H designation in the end a helicopter platform seems to be what is in mind. A 1500kg MTOW helicopter can fly with one of these engines which means 6 seats including one for a pilot. Wonderful !

EDIT: This also means that this engine is tuned for low altitude like 20k ft max rather than a high 30k ft.

TB3 would make more sense for Navy even if used from land with its heavier payload capacity.
