Firebird RZX-22 (W/ working inlet ratio)

This SR-71-like-looking aircraft is designed for research purposes.

More than anything, what starts from this is not the aircraft itself, but rather, its air intakes. They are specially designed for supersonic speeds, since they increase or decrease the efficiency of air. The truth is Very difficult to make a kind of functional turboramjet with the current physics of the game, so the best thing is to make a functional cone.

It can decrease or increase efficiency as the case may be, during takeoff and landing the engines can be stalled to reduce speed and in sustained flight they can be adjusted.to obtain maximum efficiency without the motor itself generating air resistance.

The occlusion can go from 65% (cone completely in front), until it is reduced by 45% (cone completely to the rear). Even in flight at high altitudes, shock waves can be observed going through the inlets. I suspect they work within the optimal limit of occlusion.

I really did not design it for recreational purposes, it does have calculations and research involved, despite the low thrust (intermediate 100 kn on the surface up to 85 kn in full load flight) can reach up to mach 2.8 (976 m/s).

You can adjust the size of the turbojet but it is not recommended as you have to redesign the whole system again.

It is one of the first fully functional exposed cone systems, it has a high occlusion but does not completely obstruct the air inlet.

Slider 1 for cone input.
