Feasibility and Design Definition Study of the Ramjet High Altitude Supersonic Target.
Abstract
The report presents the results of a preliminary feasibility study and preliminary design definition of a ramjet engine installation in an advanced high altitude supersonic target vehicle. The air vehicle used in the study is an adaptation of Beech Model 1069 which was flown with the first hybrid rocket motor, and the ramjet is a scaled-down version of the Marquardt MA206-XAA engine. The vehicle description and configuration are given, and the propulsion system is defined. The study indicates that the selected configuration is feasible to demonstrate supersonic flight of a ramjet engine. Simulation of flight profiles suggests that a variety of maneuvers can be flown with a simple automatic flight control system, a step-type fuel control device, and an elastometric positive fuel expulsion arrangement. Launch conditions required for the functioning of the ramjet can be met by the F-4C type aircraft and external boosters will not be required. Review of the equipment necessary for support of the system shows that existing equipment and modification of existing equipment will provide most of the support equipment necessary. Tasks necessary to complete the design are summarized. A program schedule for a flight demonstration program is included. (Author)
