UNSWEPT, UNTAPERED, MULTIWEB, ALUMINUM-ALLOY WING AT MACH NUMBERS UP TO 2.67 AS DETERMINED FROM A FREE-FLIGHT INVESTIGATION OF A ROCKET-PROPELLED MODEL

摘要

A free-flight investigation has been made on a multiweb aluminum-alloy wing at essentially zero-lift conditions to determine the aero¬dynamic heat-transfer characteristics and transient temperature distri¬bution. The test wing was unswept and untapered, having a 20-inch chord, a 20-inch exposed semispan, and -a circular-arc airfoil section with a 'thickness of 5 percent. The tests were conducted on a rocket-propelled model up to a Mach number of 2.67-and a Reynolds number of 16.0×106 based on a length of 1 foot. The test wing was also instrumented to detect flutter, but none was observed at any time during the flight test.
