Unified Engine Design

In the heart of my Blade Rocket and the LNG VTOL Plane lie my Patented unified engine. It is pressure fed in my rocket. It is fed with small, low temperature turbopumps in my LNG VTOL Plane design.

It is a unified monolithic structure composed of Tesla valve, combustion chamber and the aerospike nozzle. All printed in one piece inside a 3d printer. The printer’s building volume determines its dimensions. It would be a parametric design that can be scaled up or down depending on the requirements.

Tesla valve ensures one way flow of propellant from the tanks to the engine. The liquid exiting the valve enters the regenerative cooling canals of the combustion chamber and the aerospike nozzle. These canals are also designed in gradient hexagonal structure. This increases the surface area that the liquids can soak heat from. More importantly, it allows a stabilized pressure chamber with lower weight. As the gas builds more pressure, it increases the strength of the structure which allows higher combustion pressure. The preheated propellant than enters the combustion chamber in gas form ready to ignite. Ideally, once the fuel and the oxygen enter the combustion chamber, they would be at an auto ignition temperature. Negating the need for igniters. The exhaust gas would then be ejected from the aerospike nozzle.

Unified design reduces the path and points of failures for the liquid propellent on its path to the exhaust nozzle.

The tesla valve allows higher pressure on the combustion area compared to the pressure of the propellant tanks. Tesla valve creates a pulsating combustion which increases the combustion efficiency compared to constant fed systems. It also pulsates the exhaust gas which allow high efficiency after burner and augmented air effect. Parametric 3d print nature of the design allows different tesla geometries to be incorporated in design. This produces different pulsation frequencies. Instead of engines resonate, they create a white noise like vibrations. Additionally, gradient honeycomb combustion chamber with pressurized gas absorbs most of the vibrations before they are transmitted to the body of the rocket.
