Let me explain my patented rocket design. It started with a totally different perspective than traditional rockets. If you read my old articles, you would see the roots of the idea. I said to myself. I want to design a rocket that utilizes air’s lifting capacity and the bypass efficiency of the turbofan engines. That required the rocket to have wings and air augmentation. After several iterations I found the solution. Adding wings was just dead weight. Unlike a traditional plane the rocket is full of propellant. This turns it into a brick. The wings would just snap off. The next best thing was to reshape the rocket. The final shape was a surf board design with a wider frontal area with slightly curved front. This has the strength and surface area. It also curves towards the rear to direct the air attached to the surface to be utilized as the augmented air. Just choosing the right geometry, solved both problems at the same time. This design has a considerably weight penalty. How I solved it.
Dual purposing is like diluting the problem so that it has less effect. My orthodox design approach required all the features to be at least dual purposed to keep the idea feasible. That is something I am good at. I utilized the added support weight of the rocket to my advantage. I proposed the interior of the rocket to be gradient hexagonal monolithic lattice. This is the lightest support which is well distributed. I thought of using pressure fed rocket instead of turbopumps. The lateral structures would house the tanks. This increased the volume utilization for fuel storage compared to traditional rocket tanks. The liquid methane and LOX tank strips side by side. While the gradient hexagonal structure maintained the pressure support, the internal walls could be thinner due to minimal pressure difference inside. The dead weight of the wing structure was now supporting the pressurized liquid propellant tanks (Patented dual purposing). The internal structure was not just straight walls going from top to bottom, but had Tesla valve like structures on their way. Just curving the line appropriately added these features. Almost no additional weight needed. It solved the sloshing problem of the liquid propellant, it acted as a horizontal support to the vertical structure and allowed one way flow towards the engine (in case of a puncture, the fuel does not leak easy).
Pressure fed system allowed unified engine block. Tesla valve to allow one way flow, the combustion chamber and the aerospike nozzle. Printed as a unified structure with regenerative cooling canals embedded. The pressure of the propellants would be 600 psi. This allows the engine to operate at around 400 psi. However, pre heating of the propellant would ensure even higher pressure inside the combustion chamber. 3d printing allows almost perfect cooling performance. Therefore, the unified engine block can be printed using Al-Sc alloy strengthened by heavy PEO coating. The whole structure of the rocket would be 3d printed from Al-SC and PEO treated. The internal structure combined with Aluminum would make the rocket a giant heatsink. The internal propellent would be kept at the ideal pressure without wasting the combustion chamber heat. Atmosphere does the heating for free. Separate fuel reserves will also allow the pressure to be kept ideal for the best thrust performance.
By utilizing a pressure fed system, the rocket becomes 0-100% throttleable. The responsiveness would be also very fast negating the need for gimbaled nozzles or any other rudder system. With traditional turbopump rockets you cannot achieve perfect differential throttling.
The wing shape of the rocket reduces the engines’ maximum thrust requirement. Traditional rockets require T/W over 1 to be able to take off vertically. The wing lift capacity of my rocket lowers this number below 1. This reduces the weight of the engine block further.
Let’s come to the air augmentation part of the design. Large surface area curved to direct the air attached to the surface towards the aft section of the rocket has several benefits. Traditional rockets’ flat rear creates a vacuum effect due to sudden stop of air flow from the sides. My design has no such penalties. Air flows perfectly from the nose to the rear. The fuels in rockets are fuel rich burned to lower the combustion chamber temperature. I utilize it to my advantage. The oxygen rich augmented air would act like an afterburner for my rocket. Generating thrust boost for free. Coupled with the non-oxygen part of the air generating by pass air thrust. The overall Isp of my rocket is multiplied on the lower atmosphere. At higher speeds the engine works like a ramjet engine. This immense thrust boost counter balances al the weight penalties. Traditional rocket calculations are made as if they would only operate in vacuum. Therefore, if a rocket has low fuel to weight ratio, it is called a brick. However, my augmented air afterburner is like a virtual fuel for me (I don’t need to carry as much oxygen). Coupled with the lift advantage of the wing design which reduces the weight virtually. Now my rocket has much better fuel to weight ratio. To utilize the maximum benefit of the lower atmosphere, my rocket would have a much flatter flight trajectory on the lower atmosphere and gradually attain altitude. Thanks to the wing shape, most of the thrust can be directed to horizontal speed gain to reach the orbital velocities not to counteract the gravity (that is the main objective of any rocket).
The wing shape has other benefits when it comes to retrieving the rocket stages back. Given that the first stage also has an aerodynamic wave riding nose after stage separation (The gap between the first and the second stage would be filled by a special gasket to keep the rockets aerodynamic profile. After separation this section would be burned out. Because the second stage would fire its engine while still attached to the first stage. This burn will sublimate the gasket.). The wing shaped first stage would than glide toward the landing airfield. There, an electric trailer would catch it and slow it down. The stall speed of empty first stage would be very low. Very small amount of fuel reserve will be used for control authority. Much safer and less stress bearing recovery compared to VTOL rockets. The wave riding shape of the rocket allows it to dissipate its energy more gradually with less heating and much less stress. The first stage would be landing an airfield some distance away from the original. There it would be refueled and relaunched for a home ride. No need to keep the return fuel if you can service it on the ground.
The second stage with the same geometry would be skipping the upper atmosphere and dissipate its energy gradually before reaching the thicker atmosphere. The glider like design would allow gradual and less stress bearing return flight unlike the space shuttle. It may still have some fuel in reserve to further slowdown to minimize the heat build-up. This additional fuel coupled with the ideal heatsink design of the rocket negates the need for heat tiles which is the major point of failure on orbital return flights. As a result, both stages can be safely recovered with minimal depreciation. Much faster refurbishment is possible which further reduces the cost of operation.
