Jet Noise Reduction for Military Reconnaissance/Surveillance Aircraft. Phase II. Analysis and Design of a Quiet Research Test Vehicle
Abstract
This report presents the results of the analysis and design of a static ground test version of a Quiet Research Test Vehicle (QRTV) utilizing flightworthy propulsion system components. Also included is a discussion of the fabrication of a sufficient number of propulsive struts, employing multiple micro-jets, to propel a Schweizer SGS 2-32 sailplane up to 123 knots airspeed. The analysis and design encompasses the information required to modify the sailplane structure to incorporate the propulsion system for basic ground tests. The design of the static ground test is not covered completely. Overall consideration of the ultimate QRTV flight version has been a primary goal in the analysis and design phase of this program. As negotiated originally, the modification to the wing structure necessary to install the spanwise ducts was not a task in Phase II. Late in the program, the analysis and design of the spanwise wing duct installation was added to the program. Furthermore, hot pressure tests of a sample production propulsive strut were also included. Results of these two additional tasks have been incorporated as appendices in this report.
