    I like those Daniel Raymer designed/invented-type ruddervators.

    Big hand to Dan everyone ! :applause:

    Here is a film to watch about the difficulties a private new combat aeroplane is facing; http://www.nfb.ca/film/defender/

    The designer Robert Diemert and co worker mr.Bell are kinda like Batman and Robin.

    See how the T-72 are dug in and camouflaged; http://englishrussia.com/2012/02/01/the-6th-tank-brigade-technique-and-training/ …they may have a point ?

    I figure the drop tanks are only dropped when in case of emergency…ie in combat for greater maneuvrability.

    Is this an old episode of the Benny Hill Show?

    De Hallivand Gnat sounds like it.

    Anyway Mirage IIIA-01 was only 13.01 meters long…and Mirage I just 11 meters.

    LCA Tejas is 13.20 and sporting a lot more power than Mirage IIIA.

    My approach is totally different.

    I have a 13 kN engine ( + 2 x 6 kN boosters ) and just above 9 meters long craft with natural flying capabilities ( empty weight close to 1500 kilos )…ie not computer flown fly by wire system.

    See how much F-22 control surfaces turn…alone those surfaces at those deflections would cause such a massive drag in my plane that it would immediately stall.

    [ATTACH=CONFIG]217461[/ATTACH]

    Folland Gnat and HA-300 Helwan are about the only kites you can compare this with ( ARES and early Mirages perhaps )…even LCA Tejas is massive compared to this.

    I like Tejas materials !

    Topspeed, please just ignore the haters and obvious trolls. I hope you do realize that Iran is not an option for you right now. The country is subjected to heavy trade sanctions and weapons export embargo-laws which are recognized by all UN member states.. And they are there for a reason. So you will be at great risk of violating international law if you start dealing with the Iranis. Even only on pure consultation-basis. And getting caught with something like that can (will) give you and your aviation design programmes some serious troubble.

    IMHO it would be better (and most likely far better monetary compensation) for you to look att ongoing but “troublesome” projects like the Tejas/Tejas II, and offer your services to find alternative (and sometimes radicaly new/surprising) solutions to solve these bottlenecks, anf get the programme back on track again. The Indians need all the input/help they can get right now, thats for sure.
    Your deep knowledge/familiarity with smaller jet engines (combined with RATO-bottles if needed) as well as the Indians previous “mini-fighter”, De Hallivand Gnat, wouldn’t make you any less interesting to the HAL project managers me thinks…
    But stay away from the Iranis!

    Well, other than that, I can only say that it is very pleasing to see that the VR-programme has moved on to an actual flight testing phase (albeit still in minature form)! This should give you som very valuable first hand experience of basic aerodynamics. Oh, and I saw that your thinking of modifying the VR-1 so it can carry two AMRAAMs?? I think its an excellent idea! Better two big BVR AAMs that ten Stingers. This li’ll baby is gettin some serious claws.. 😎

    Thank you for the kind words Griffon39 !

    I think India could be one…and Iceland and Lithuania…maybe New Zealand…perhaps Papua New Guinea ( without JASSM-158s preferably ) ?

    There is 2350 kg of missiles on it now.

    Er….and it was Folland Gnat by mr.Petter !

    One should never give up trying…slight increase in size and voila…2 AMRAAMs fitted inside in concealed weapon bays.

    Hold on. You’re not honestly expecting a foreign government to contact you after seeing some line drawings on a hobbyist website are you? Have I missed something somewhere? :confused:

    Not just any government or AF or engineering company but someone from not terror related country.

    Are you saying seeing is not believing ? See I am an architect ( with serious aviation bug bite ) not an civil engineer and I only believe what I see and flies well ( ..even as a scale model ).

    I have also conducted research with x-foil based design program and gotten excellent results ( in efficient foil designs ). Also checking data with normal trivial equations to be on the reasonable terms with reality.

    Much bigger plane has long long time ago gone faster than MACH 2 with just 26.7 kN; http://en.wikipedia.org/wiki/Bell_X-1

    GM-1 is roughly 20% smaller than Bell X-1E. GM-1 sports 13+12 kN thrust ( PW530A + 2 x 6kN Galcit rockets ).

    I think I am going to try to fit concealed AIM-120 AMRAAMs on this. The MBDA MICA seems to be less NATO stuff ( sales are not skyrocketing ) ?

    I couldn’t fit the AMRAAMs in the GM-1.

    Here is studied slightly after the Diemert’s Defender the VT-AERO with A-10 and ARES.

    Actually the J-21 looks quite a lot like the model being tested in Russia a decade ago.. it looks like the YF-22 at first but its actually smaller if you look at the proportions, much closer to the J-21 size. Since Shenyang is very close with Russian companies, its entirely feasible they received Russian assistance

    http://paralay.com/t50/m101.jpg

    Isn’t J-21 much bigger than F-22 ?

    I appoximated that this kite will go beyond mach 2 with only 25 kN of thrust.

    I am looking forward to any kinda co-operation in this within the nations/states that are not terror related.

    The planes from smallest to biggest are ( BIGGER CHART ABOVE ):

    1. VT-AERO ( vlo )
    2. GM-1 ( stealth )
    3. Gnat ( mach 1+ in dive )
    4. VL Puuska ( project )
    5. HA-300 ( mach 2+ )
    6. Me-163
    7. Me-109 G
    8. P.1101 ( unfinished )
    9. LA-15 ( few prototypes lost to Mig-15 )
    10. ARES
    11. MIG-21
    12. F-22 ( stealth )

    I was about to say that Topspeed has a very bright future if he wants to make a ton of money working for the Iranian aersospace industry 🙂 , but yeah the pictures do remind me a lot of the way chinese photos are released by the authorities…Only things missing are a few bushes, some trees and some more grain …

    Funny I don’t feel like I am being flattered ?

    The model inflight is 190 times smaller than a J-20…might that make it a bit grainy ?

    The nexs smallest etc might be found out looking at these pics. Someone claimed HA-300 was smaller than Gnat…it ain’t so.

    But HA-300 is smaller than P.1101 and naturally thus second smallest military jet ever to see the skies. Amazingly also HA-300 is smaller than Me-109 G-14 ( Ernst Heinkel was pissed off when 80 km/h slower AC superceded his design He-100D to become the standard Luftwaffe fighter ).

    Here is small chart with very small and very efficient jets..from different era as well.

    4 are from Willy Messerschmitt and 2 US and 1 UK design and 2 USSR.

    VT Aero is the smallest by far..then GM-1..and Gnat and then PUUSKA.

    BD-10 was awesome jet that had over 1:1 power to weight ratio ( unfortunately ). Rutan used similar sized engine in larger ARES ( which only was capableto reach speeds of mach 0.6 ) which also carried GAU-12.

    http://www.youtube.com/watch?v=TZGB32keRfw

    It does look like a cheap toy ( to be marketed as a supersonic homebuilt )…and despite claim of mach 0.9 cruise…it never went faster than Mach 0.83. It should have have a sticker in the dashboard DO NOT EXCEED 400 MPH !

    Here is a good site to show/explain what flutter analysis is for; http://www.aircraftdesigns.com/aircraft-flutter-analysis.html
