FLIGHT INVESTIGATION TO DETERMINE LIFT AND DRAG CHARACTERISTICS OF A CANARD RAM-JET MISSILE CONFIGURATION IN THE MACH NUMBER RANGE OF 0.8 TO 2.0

摘要

A flight investigation has been conducted on a canard ram-jet mis¬sile configuration to determine its lift and drag characteristics at low values of lift. The configuration consists of two ram-jet engines mounted on a composite wing having leading-edge sweepback of 0° inboard of the engines and 60° outboard of the engines;the canard is of the delta type with a 60° leading-edge sweepback angle. Two rocket-boosted models, dif¬fering only in the size and deflection of the canard, were employed in the investigation.nThe lift and drag data were obtained in the Mach number range of 0.8 to 2.0 with the Reynolds number varying from 3 X 106 to 14 X 106 , based on wing root chord.nIt was found that in the supersonic speed range of the tests the effectiveness of the canards in producing model lift is nearly directly proportional to their exposed areas.
