Problems Associated with the Development and Operation of a Cryogenic Cooling System for the X-15 Airplane
The purpose of this paper is to discuss the use of liquid nitrogen for cooling and pressurizing the X-15 airplane cabin and equipment bay. The discussion will cover theoretical and actual flows obtainable through fixed flow-control orifices, temperature-modulated demand-type liquid-nitrogen injectors, and the interaction of two or more fluid-carrying systems being fed from the same source upon each other. In order to show the relationship of the system to the airplane, a short description of the vehicle may be useful.
