RISNASA-LLIS-3099: Lessons Learned - Dome Heat Shield Alignment Tool
Abstract: Abstract:
A simple tool consisting of a tapered bolt, a nut, and two close-tolerance "hat" bushings can be used to align two holes, without the use of undesired force.

NACA-TN-2114: Theoretical lift and damping in roll of thin wings with arbitrary sweep and taper at supersonic speeds: supersonic leading and trailing edges
Abstract: The analysis is limited to wings of vanishingly small thickness that have zero camber. The results are valid only for a range of supersonic speeds in which the components of the free-stream velocity normal to the leading and trailing edges are supersonic. These conditions are now commonly expressed by the term "supersonic leading and trailing edges...
NASA-TN-D-8391: Calculations, and comparison with an ideal minimum, of trimmed drag for conventional and canard configurations having various levels of static stability
Abstract: Classical drag equations were used to calculate total and induced drag and ratios of stabilizer lift to wing lift for a variety of conventional and canard configurations. The Flight efficiencies of such configurations that ...
NACA-TR-1284: Theory of wing-body drag at supersonic speeds
Abstract: The relation of Whitcomb's "area rule" to the linear formulas for wave drag at lightly supersonic speeds is discussed. By adopting an approximate relation between the source strength and the geometry of a wing-body ...
NACA-RM-L8I03: The effects of high-lift devices on the low-speed stability characteristics of a tapered 37.5 degree sweptback wing of aspect ratio 3 in straight and rolling flow
Abstract: Contains results of tunnel tests to determine effects of various combinations of split flaps, slats, and nose slats on the stability characteristics of a tapered 37.5 degree sweptback wing of aspect ratio 3 in straight and ...
NACA-TR-589: An analysis of lateral stability in power-off flight with charts for use in design
Abstract: The aerodynamic and mass factors governing lateral stability are discussed and formulas are given for their estimation. Relatively simple relationships between the governing factors and the resulting stability characteristics ...
NASA-STD-7002 REV A: PAYLOAD TEST REQUIREMENTS
Abstract: This standard includes selected environmental exposure tests for hardware operating in earth orbit. The tests included are generally regarded as the most critical and the ones having the highest cost and schedule impact. ...
NASA-TM-X-35: Effects of vertical-tail size and a ventral fin on the static lateral and directional stability derivatives of a 0.048-scale model of a horizontal-attitude VTOL airplane at transonic speeds
Abstract: Vertical tail size and ventral fin effects on lateral and directional stability of VTOL AIRCRAFT at transonic speeds
NASA-LLIS-1404: Lessons Learned - NASA Engineering and Safety Center Consultation on Mars Exploration Rover Ground Operations Human Factors
Abstract: Abstract:
The existence of Agency-wide standards for work time limits for personnel engaged in critical flight operations has apparently not been widely communicated across NASA. The standards need to ...
