See how clean this consept is...no interference drag ( practically ) !.

Seem to work again;
To understand why V-RAPTOR can go mach 3 + with rockets read this; http://en.wikipedia.org/wiki/Bell_X-1 VR has 2.5 times less frontal area and burns rockets only 3 minutes. More data added:
Someone asked how come I get such high climb rate with such a small engine power. I also counted very high speed with fan alone burning just same as what Me-109 G-6 burned on combat. See the size. This Gekko/Velociraptor is 1.58 times smaller than already small 109...but this has more wing area...at high you can go fast with rockets. See Bell X-1 it was similarly sized as 109. It had only 27 kN thrust and went MACH 2.25 and into 27 KM ! Gekko can go at 36 + 7.32 kN up to 15 KM. Where the fan is shut down and inlets closed.
You should concentrate on building design
ReplyDeleteThere is less building design going on right now. Thanks for the comment !
ReplyDeleteDon't you think reducing the fossil fuel burn on fighters to 1/60 deserves for any purpose ?
ReplyDeleteHow can you get such climb rates with such low enginepower? Good aerodynamics make speed, power makes climb rate.
ReplyDeleteNo power has little to do with it. This has 160-360 kg/m2 wingloading and size is 1/5th of a JSF F-35 or F-22 RAPTOR. It is the power to weight ratio and cleaniness of the consept. Me-109 had 2 x better climb rate than a P-51D.
ReplyDeleteWhat is the power to weight ratio today? If you want to make 2000 kilo thing climb fast, you'll need close to 2000 kilos of thrust.
ReplyDeleteThis has 2 x 18 + 7.2 = 43.2 kN thrust.
ReplyDeleteMinimum take off weight is around 3400 kg.
it is then 1.27 power to weight ratio...pretty massive.
