NASA-LLIS-1342
Abstract: Description of Driving Event:
Due to three major factors the Project's budget was not sufficient to meet its primary objectives. One, the Project was the most significant and often times only customer ...Subject(s) : Logistics , Policy & Planning , Risk Management/Assessment , -
NACA-RM-L8G05
Abstract: INTRODUCTION
A wing having triangular plan form, 60° of sweepback at the leading edge, and 10-percent-tuck biconvex airfoil sections has been tested in the Langley full-scale tunnel as part of a general investigation ... -
NACA-TN-1813
Abstract: A study of experimental pressure distributions and sections was made. A correlation appears to exist between the drag-divergence Mach number and the free-stream Mach number and the free-stream Mach number for which sonic ... -
NASA-LLIS-2776
Abstract: Abstract:
The Logistics organization treats parts as parts only, with no provisions for storing related parts as kits. Because of the nature of the Thermal Control System (TCS) blankets and supports, ...Subject(s) : & Processes , Configuration control and data management , Configuration Management , Ground Operations , Ground processing and manifesting , Handling , Logistics , Materials , Mishap Reporting , NASA Standards , Occupational Health , Packaging , Parts , Payloads , Personal Protective Equipment , Policy & Planning , Pressure Vessels , Procurement , Program and Project Management , Range Operations , Research & Development , Risk Management/Assessment , Safety & Mission Assurance , Security , Small Business & Industrial Relations , Software , Spacecraft , Standard , Storage , Test & Verification , Test Article , Test Facility , Training Equipment , Transportation , -
NASA-LLIS-0364
Abstract: Abstract:
