Wind tunnel tests on sonic boom with models of three wing-fuselage combinations
Equations for predicting aerodynamic stability of bodies of revolution with offset centers of gravity at supersonic and hypersonic speeds
Star background to reduce position error in photographic geodetic observations
Simultaneous photographs taken at different ground stations against star backgrounds used to correct measurements of objects moving in upper atmosphere
Leading edge and trailing edge flap deflection effect on high left and lateral control characteristics of semispan variable sweep wing and tail surfaces
Aerodynamic characteristics of aircraft configuration for low level supersonic attack tested in transonic wind tunnel
Economics of cost structure in scientific research facilities
Satellite data on particle density and magnetic field intensity in Earth region towards Sun and causes of data scatter
Torque wrench with an adjustable drive shaft permits indicator to remain in view when used on sections of equipment with limited access. The shaft is capable of protruding from either side of the wrench head by means of spring loaded balls.
Laser activated ultraprecision ranging apparatus interfaced with a computer determines point coordinates on a photograph. A helium-neon gas CW laser provides collimated light for a null balancing optical system. This system has no mechanical connection between the ranging apparatus and the photograph.
Cost structures in research facilities to establish cost or efficiency criteria for spatial allocation of funds, and decentralized decision making
Probability density function and distribution function of distance from random point in polygon to the nearest corner in lattice
Internal flow performance of fixed 14 deg ramp inlet from zero to 20 deg angle of attack at supersonic free stream
Annular cascade investigation to provide design criteria for slotted rotor and stator blading
Thermal emittance of cone and cylinder cavities electrically disintegrated in tungsten and molybdenum measured with disappearing-filament pyrometer
Model of reentry plasma layer consisting of magnetic line source in ground plane, determining plasma temperature effect, computing radiation pattern of far-zone field
