This aircraft is constructed according to the concept os point-defense interceptor around a very powerfull multi-bank piston engine with a very high power to weight ratio. A fantastic climb speed is achieved, but still having fuel for 30 minutes combat time.
The two-stroke engine is supercharged with mechanical two-stage compressors and the exhaust gases produce additional thrust. High octane fuel and Methanol/Water injection and/or Nitrous Oxide injection is also used.
Similar formula was studied by the British before and during WWII with the Rolls-Royce Crecy, but practical results were obtained later with the four-stroke, 24 cylinder Napier Sabre engine.
Rocket engines and afterburners relegated the formula to oblivion.
