NASA-TN-D-30: Flight Investigation of the Lift and Drag Characteristics of a Swept-Wing, Multijet, Transport-Type Airplane
Abstract: The lift and drag characteristics of a Boeing KC-135 airplane were determined during maneuvering flight over the Mach number range from 0.70 to 0.85 for the airplane in the clean configuration at an altitude of 26,000 feet. ...
NASA-TP-1020: Theoretical parametric study of the relative advantages of winglets and wing-tip extensions
Abstract: It was found that for identical increases in bending moment, a winglet provides a greater gain in induced efficiency than a tip extension. Winglet toe-in angle allows design trades between efficiency and root moment. A ...
NASA-TN-D-6142: Vortex-lattice FORTRAN program for estimating subsonic aerodynamic characteristics of complex planforms
Abstract: Vortex-lattice FORTRAN program for estimating subsonic aerodynamic characteristics of complex planforms.
NASA-TN-D-1057: Analysis of X-15 landing approach and flare characteristics determined from the first 30 flights
Abstract: The approach and flare maneuvers for the first 30 flights of the X-15 airplane and the various control problems encountered are discussed. The results afford a relatively good cross section of landing conditions that might ...
NASA-TN-D-7137: Modeling of airplane performance from flight-test results and validation with an F-104G airplane
Abstract: A technique of defining an accurate performance model of an airplane from limited flight-test data and predicted aerodynamic and propulsion system characteristics is developed. With the modeling technique, flight-test data ...
NASA-TT-F-734: Flight of aircraft with partial and unbalanced thrust
Abstract: The problem of aircraft operation under conditions of unbalanced thrust following the failure of an engine on a multi-engine aircraft is examined. The dynamics of the divergent motion of the aircraft immediately after ...
NASA-TR-D-640: The aerodynamic characteristics of full-scale propellers having 2, 3, and 4 blades of Clark y and R.A.F. 6 airfoil sections
Abstract: Aerodynamic tests were made of seven full-scale 10-foot-diameter propellers of recent design comprising three groups. The first group was composed of three propellers having Clark y airfoil sections and the second group ...
NASA-CR-135307: Aerodynamic performance of conventional and advanced design labyrinth seals with solid-smooth abradable, and honeycomb lands
Abstract: Labyrinth air seal static and dynamic performance was evaluated using solid, abradable, and honeycomb lands with standard and advanced seal designs. The effects on leakage of land surface roughness, abradable land porosity, ...
NASA-TR-D-594: Characteristics of six propellers including the high-speed range
Abstract: This investigation is part of an extensive experimental study that has been carried out at full scale in the NACA 20-foot tunnel, the purpose of which has been to furnish information in regard to the functioning of the ...
NASA-TP-1917: Cornering characteristics of the nose-gear tire of the space shuttle orbite
Abstract: An experimental investigation was conducted to evaluate cornering characteristics of the 32 x 8.8 nose gear tire of the space shuttle orbiter. Data were obtained on a dry concrete runway at nominal ground speeds ranging ...
