    Featured Pakistan's Shahpar II UAV Unveiled

    Possibly. I suppose Turkish members can shed more light. Google says the Rotax912 powers the TB-2. This is the same engine that powers the Shahpar-I. If you look at the engine's data sheet: It only goes up to 7500 m (24,600 ft) and at that altitude you have 20-30 kW. I suppose with very smart...

    Featured Pakistan's Shahpar II UAV Unveiled

    I am actually quite fascinated how the TB-2 can climb to 27k feet with a piston engine. It has to be supercharged/turbocharged or something. The TB-2 is a good 200 kg lighter than the Shahpar-II but weight alone cannot allow a piston engine to operate at those altitudes without help.

    Hmmm...so cruising at 80 kts for 5 hrs (taking 2 hrs off for takeoff, climb, descent, and landing) you can travel almost 800 km, and half of that is 400 km, which is 100 km more than the MTCR number right? The line-of-sight data link range is 300 km though. I suppose that's how Shahpar-II...

    I am pretty sure that endurance figures are between wheels up/wheels down. Time on station would require you to state or assume how far away the station is. As far as I know, this is not done. Did I parse your statement correctly? If so, I don't quite follow why an endurance metric from takeoff...

    Thank you for your reply regardless! I agree with what you said, and I did think about it. However, the reason I was curious was that the addition of two missiles should NOT halve the endurance merely due to aerodynamic effects. An equation for endurance used for preliminary design is: With...

    That is true of course. doubt this very much. Chinese equipment is cheaper compared to western alternatives but it is not dirt cheap. I recall seeing quite a ridiculous cost for the import of 100 Chinese REK's. I suspect that their high cost was one of the reasons for the development of the...

    @Bilal Khan (Quwa) Is the reduction in the endurance of the armed version an MTCR thing? It could also be just the replacement of the armament weight with internal fuel weight. Or both.

    That is precisely what I was thinking about. Thank you for posting those brochures, I had gotten lazy trying to find them. People tell me less and less the more I break news haha. It is only natural. To answer your question, I have no idea. Honestly, I was a little surprised to see the...

    Also, let me just add that I would expect a bigger payload and a higher cruise speed with a turboprop. Thank you for those details! They are certainly insightful! The TB-2 makes a natural comparison for the Shahpar-II and presents where it may go in the future. I do wonder how the TB-2 is able...

    Featured Pakistan's Shahpar II UAV Unveiled

    No, I am not forgetting the square-cube law. If Shahpar-II with the Rotax 912 has "absolutely zilch chance" of taking off, how do you explain the Bayratkar TB-2 taking off, which as I pointed out, has almost the same same dimensions and a 100 hp piston engine? To further my point, a 100 hp...

    Funny you should mention turboprop. The first draft of my post had speculated that Shahpar-II might be designed with a turboprop in mind due to the dual (top and bottom) intakes and very large exhaust, which looks overkill for a piston engine. However, I thought that this might be for cooling...

    Featured Pakistan's Shahpar II UAV Unveiled

    Something to think about: Shahpar-I is powered by a 100hp Rotax 912 according to official specifications: and a look at the aircraft's rear shows the engine taking up all of the space: Now compare this to the rear end of Shahpar-II: Shahpar-II is certainly much bigger, as we've already...

    Oh Karrar, is that what it's called? I didn't know. Which should tell you that I know little about that effort. NESCOM's Anka might just be a workshare type agreement. I don't know if NESCOM is planning to produce the entire thing in Pakistan. That was my thought too but very very clearly the...

    Yeah. Just look at Harbah. I am pretty sure we will see the same with YJ-12 (or HD-1A) being inducted as SMASH, CM401 being inducted as P282.

    These missiles are monsters. I would suspect that this missile is a large part of the reason for getting these ships. The induction of these missiles complicates IN wartime operations.
