NASA-LLIS-0435
Abstract: Abstract:
A SEASAT-A subassembly was damaged during thermal-vacuum test due to the configuration of GSE test equipment. A reed relay in a commercial data scanner was connected to circuits requiring +5 ...Subject(s) : Configuration Management , Energy , Flight Equipment , Ground Equipment , GSE Interface FMECA , Hardware , -
NASA-LLIS-0235
Abstract: Description of Driving Event:
A wind turbine was lowered from its tower and secured to a ground level assembly stand. A blade tip was then removed and the work crew broke for lunch. After lunch the ...Subject(s) : Industrial Operations , Lifting Devices , -
NACA-TN-1270
Abstract: The aerodynamic characteristics of seven unswept tapered wings were determined by calculation from two-dimensional data and by wind-tunnel tests in order to demonstrate the accuracy of the calculations and to show some of ...Subject(s) : AIRFOIL , AIRFOILS , ASPECT , CHARACTERISTICS , LARGE , MOMENTS , NACA , PITCHIN , PRESSURE , RATIO , ROUGHNESS , SERIES , STALLING , SURFACES , TAPERED , TESTS , TUNNEL , WIND , WINGS , -
NASA-TN-D-6575
Abstract: A summary was made of all NASA (and NACA) research and experience related to the spin and recovery characteristics of light personal-owner-type general-aviation airplanes. Very little of the research deals with light ... -
NASA-LLIS-1252
Abstract: Description of Driving Event:
Since the award of the Basic Space Station Contract numerous changes have been authorized, but there was no consistent, established method of authorizing and notifying the ...Subject(s) : Administration/Organization , Configuration Management , Independent Verification and Validation , Policy & Planning , Procurement Small Business & Industrial Relations , Risk Management/Assessment , Safety & Mission Assurance , Test & Verification , -
NACA-RM-L51L10
Abstract: INTRODUCTION
The spoiler used as a lateral-control device has been the subject of considerable investigation at low and high speeds, and on both swept and unswept wings (references 1 to 7). Many of the advantages ... -
NASA-TN-D-7351
Abstract: An investigation was conducted at the Langley aircraft landing loads and traction facility to determine the cornering characteristics of a 40 x 14-16 type VII aircraft tire. These characteristics, which include the ...Subject(s) : AIRCRAFT TIRES , COEFFICIENT OF FRICTION , CONTACT RESISTANCE , DATA ACQUISITION , EQUIPMENT SPECIFICATIONS , PERFORMANCE TESTS , SURFACE PROPERTIES , -
NASA-LLIS-0099
Abstract: Description of Driving Event:
An APU hydrazine isolation valve assembly was removed and sent to the shipping section of logistics without being properly packaged for safe handling. In addition, there ...Subject(s) : Energetic Materials - Explosive/Propellant/Pyrotechnic , Hardware , Hazardous/Toxic Waste/Materials , Packaging Handling Storage , -

NASA-LLIS-0655
Abstract: Practice:
Conduct a formal Preliminary Design Review (PDR) at the system and subsystem levels prior to the start of subsystem detail design, to assure that the proposed design and associated implementation ... -
NASA-LLIS-1561
Abstract: Abstract:
A. Reviews: General feedback received from all levels of project participants There are too many reviews without clear definition of their purpose. As a result, reviews tended to overlap in ...Subject(s) : AATT , Budget , General Feedback , Independent Verification and Validation , Policy & Planning , Program and Project Management , Reporting , Reviews , Schedule , Technical Publications , -
NASA-LLIS-1422
Abstract: Abstract:
Ensuring that a Project's collective wisdom is collected, archived, and disseminated depends on including a schedule, budget, and process for their accomplishment in the Project plan.Subject(s) : knowledge capture , knowledge dissemination , Project closeout , Risk Management/Assessment , Safety & Mission Assurance , -
NACA-RM-L7E13
Abstract: Wind-tunnel investigations were made in pitch and yaw with and without split flaps. Presence of the fuselage had negligible effect on values of maximum lift coefficient and slope of lift curve, but caused a destabilizing ...Subject(s) : FLAPPING , FLAPS , FUSELAGES , SPLIT , WINGS , -
NASA-LLIS-0410
Abstract: Abstract:
Mutual interference among the two Viking Orbiters and the two Viking Landers caused a loss of downlink carrier lock and telemetry data several times during the Viking extended mission. The ...Subject(s) : Communication Systems , Flight Equipment , Ground Equipment , Multiple Mission Planning , Spacecraft , -
NASA-LLIS-0207
Abstract: Description of Driving Event:
A very disorganized system of making, archiving, and reporting natural environmental conditions at KSC has evolved. Several organizations make measurements and archive ...Subject(s) : Administration/Organization , Environment , Launch Process , -
NACA-TN-808
Abstract: An investigation was made in the NACA 7- by 10-foot wind tunnel to determine the effect of slot-lip location on the aerodynamic section characteristics of an NACA 23012 airfoil with a 30-percent-chord slotted flap. Tests ...Subject(s) : AIRFOILS , CHAR , CHORD , DEVICES , EXTENDED , FLAPS , FOWLER , FULL , HIGH , LIFT , LIP , LMAL , MOMENTS , NACA , ORDINATES , SLOTTED , WING , WINGS , -
