Abstract: A method of landing a capsule-spacecraft having a crew compartment containing crew, light cargo, and whatever other elements are associated with crew safety and comfort during emergency recovery, such as survival equipment and a service component including any propulsion components, heat shield, heavier structure, or other equipment not directly connected with the crew component. In the event of a propulsion system failure, the crew compartment component is immediately separated from the service component, either by automatic or crew action. One or more parachutes are then deployed by rapid methods, such as rocket extraction, from the crew compartment. Because the space craft is separated into two parts the weight of the parachutes is reduced in proportion as the weight of the crew compartment is to the total capsule-spacecraft.

Abstract: An orbital stage system has an orbital stage and one or more launch stages. The orbital stage incorporates an orbital maneuvering system (OMS) and an abort propulsion system which both utilize the same propellants, propellant tankage, and propellant pressurization system, but which employ radically different engines. The OMS engines are comprised of at least two engines which have a combined thrust in the neighborhood of 1/10 the weight of the orbital stage, an area ratio of 50 or more and an operating life of many hundred seconds, preferably many thousands of seconds or more. The abort engine may be a single engine and typically has a thrust of three, four, or more times the weight of the vehicle and an area ratio in the neighborhood of two and an operating life of at most a few tens of seconds.

Abstract: A turbojet engine with improved thrust and high-altitude capabilities. Arrangements are provided for injecting liquid oxygen or other oxidizer into the turbojet engine before the compressor section. Cooling the incoming air by the liquid oxygen reduces the air volume, which allows a fixed inlet to be matched to varying flow conditions, allowing a greater mass of air to be ingested by the compressor section and results in a lower compressor outlet temperature. Increased mass flow, combined with more fuel results in higher exhaust gas temperatures and greater thrust. The addition of oxygen to the inlet air flow allows the engine to operate at higher altitudes by preventing flameout due to rarefied air.

Abstract: A launch vehicle which employs a rotor similar to a helicopter. The vehicle has a four bladed rotor which is mounted on the vehicle body. The body of the vehicle includes propellant tanks and a payload compartment contained within an integral aeroshell. Rocket engines used to propel the vehicle into earth orbit are mounted at the ends of the rotor blades. The engines are connected by propellant feed lines to a propellant transfer hub surrounding the axis of rotation of the rotor. Propellants are fed from an oxidizer tank and a fuel tank through a propellant transfer coupling to oxidizer and fuel lines which extend to the engines at the rotor blades ends. The rotor blades incorporate air foils. To operate the vehicle the vehicle is positioned on a concrete or asphalt pad and fueled with liquid oxygen and kerosene. The engine are positioned tangent to the blade paths and ignited.
