If our state or private defence companies were to wait for tenders before they started research and development of new platforms, we wouldn’t be able to get anywhere. All companies need to know how to take initiative and develop platforms like these. Hurjet was the same. All produced with...

It is nice to read a foreign perspective of these events and geopolitical developments concerning Turkey. Regarding nuclear deterrent, I personally don’t agree that only a few “elite” nations should have the access to nuclear weapons. It should really be banned altogether. If not, then it is...

The red lined area of the 200watt TR module in my last post where the GaN chips are, for half the power output, would approximately equate to a size you are defining.

I am not a radar specialist and wouldn’t dare to speculate on it even with my engineer hat on. But I have a feeling that this is a multi module unit with power source, cooling system and all other paraphernalia included in one box. Below is a picture of a 200 watt S band GaN TR module. What you...

https://www.mistralsolutions.com/defence_products/trmm/ Here is a company producing GaN modules for Aesa radars and quoting 100watts peak power. Like all transistor powered audio amplifiers, that in effect may use similar MOSFET circuits albeit slower than GaN FETs, you do not drive your...

Dear members please stay on topic. This is TFX Fighter and Trainer aircraft projects thread. Any one trying to derail the thread towards political discussions will be given a warning . All posts concerned have been moved to Foreign policy and geopolitics thread. Please carry on with your...

I had mentioned this before about Akaer, that they are very much involved in the design and development of structure and airframe geometry of our Hurjet. You have rightfully highlighted this issue in your post. They are the right people to be associated with when it comes to airframe design for...

https://www1.grc.nasa.gov/wp-content/uploads/NASA-Glenn-Airplane-Parts-Image-2.jpg You are absolutely right. Yaw for vertical stabilisers and for side to side. Pitch is for horizontal stabilisers and for up and down. Corrected accordingly.

Vertical stabilisers are there to control yaw (side to side movement of nose). Horizontal stabilisers help control pitch ( up and down movement) On a delta wing aircraft Elevons/ailerons and flaps take over this duty. https://wcc.ep.liu.se/index.php/TMAL02/article/download/559/473/646 But as...

Although thrust vectoring gives a definite advantage in agility and quick manoeuvrability, the advantage obtained has not been a game changer or a must case. In fact information to the contrary has been more prevalent. Just to give you a quick example; The EJ200 engine has had a TVC version...

Sixth Generation fighter jet expected properties have been discussed here in detail before. 1. All 5th generation specifications will be there and will be improved. 2. Involvement of pilot in flight will be minimised; Improving AI for most functions will make these planes capable of being...

https://www.defenceturk.net/altinay-gemiler-icin-helikopter-yakalama-ve-transfer-sistemini-yerlilestirdi After Canada placed an embargo on it, Altinay Defence has managed to indigenise the “ASSIST” system that captures helicopters and aids them to be pulled in to hangar on sea platforms. Well...

From a gas turbine engine point of view you are correct. It would also mean that we would need maintenance crews that understand turbine engine technology. Actually, Prof Aksit was asked the question about which company is best suited to produce a tank engine for Altay when in early 2015...

Both assumptions have valid points. Altay, fits in to the category of tanks that need to be supported by infantry. Also it is not a tank that should be driven in to urban warfare. Even if it is supposed to give support to AFVs and other lightly armoured units. Altay may take a long time to be...

That is the idea behind this modernisation to a certain degree. Also a tank like Altay would be too valuable and behemoth of an asset to push forward for quick, fast surgical strikes to give support to infantry armoured columns. A lighter and more capable alternative that is closer to a medium...

Later engines may well have 4th generation blades. But as you can see from below paper that 4th generation blades were still being developed by December 2004. F119 engine was being developed in early 1980’s. F22’s and f119’s maiden flight was in 1997. P&W was given the contract to produce the...

Someone ought to explain to the program planners the physics and effects of metal fatigue in machinery. Here we are criticising the purchase of 20+ year old Type 23 frigates because of their age; Yet our tank engineers are contemplating “modernising” a tank tech that was first put in to active...

Good informative paper. Since its first introduction in to gas turbine engines in 1982 by Pratt & Whitney, single crystal blades have been going through many transformations. By adding rare metals like Rhenium or rhodium in small amounts, the heat resistance properties of blades have been...

There are two different tanks in western armed forces: 1. Tanks with rifled guns, whose main purpose is to give support to infantry and to spearhead surgical strikes in to enemy positions with HE and HEP rounds. For these tanks to knock out an enemy tank with a sabot round is secondary; Their...

According to @Anmdt ’s above post, first steel cutting of I-Class ’s 3 new ships will start in April this year. They give a time frame of 36 months before ships are delivered. But in 6 monthly intervals. That makes it Mid 2027 before all 4 I-Class ships are in our inventory. Now some members...
