LNG Plane Updated

I made some design changes on my LNG VTOL Plane and would like to explain them. I draw the plane from different angles to further clarify its details. The plane utilizes the unified rocket engine I proposed earlier. There would be 8 VTOL and 2 aft engines. All engines would be fed by low temperature turbopumps which have much longer service life than the rocket counterparts and cost way cheaper. This lowers the pressure therefore the weight requirements of the tanks. VTOL engines would utilize LOX as the oxygen source. LOX tank would be embedded inside the LNG tank to have insulation and reduce its weight. Using LOX reduces the weight of the engines and lowers the dead weight on the VTOL. After takeoff there would only be small amount of LOX in reserve for landing. The tandem bi-plane design lowers the cross section for VTOL and increases the total lifting surface area. The lack of engines below the wings and the vertical support on the edges make them very thin and sturdy. As a result, the wings would have less drag than the traditional planes. The vertical supports double as vertical stabilizers and the drag inducing heavy tail stabilizer would be removed from the traditional design.

Only the aft engines, (two because of redundancy), will be air breathing. There would be centrifugal air compressors embedded on the top aft section of the plane to supply air to the main thrust engines. The unified rocket engines create very hot pulsating exhaust gas at the back of the plane. Coupled with the augmented air due to Coandă effect, there would be considerable thrust boost for free. The augmented air would generate after burner effect and low bypass air propulsion. The lack of turbofan engines besides the fuselage creates smooth surface for the air to attach to until the rear of the plane where the unified engines are mounted.

The cargo bay of the plane would be behind the passenger cabin. Unlike the passenger cabin it would be unpressurized. The cargo bay would be removable by a special robotic lift on the ground. Which allows rapid cargo load / unload times without damaging the baggage. The removal of the cargo bay would reveal the air intake pipes and the aft engines. As a result, during cargo processing time the critical parts of the engine can be inspected with ease.

LNG Tank and its details were explained in the previous article. As the plane clears the ground, it would be generating horizontal speed to lower the fuel and LOX consumption of VTOL.
