NASA-LLIS-0433
Abstract: Abstract:
Voyager's discovery of defective component lots in welded module assemblies led to a reprocurement of the flight relays. For procurement of parts with a prior history of problem/failures, ...Subject(s) : Parts Materials & Processes , Test & Verification , Wire Welding , -
NASA-LLIS-0233
Abstract: Description of Driving Event:
A deactivated exhaust gas cooler in a vacuum line collapsed under normal operating conditions of 26 inches of mercury. The cooler was destroyed. There was minor damage to ...Subject(s) : Ground Equipment , Hardware , Industrial Operations , -

NACA-TN-1245
Abstract: INTRODUCTION
The lateral-control research that had been conducted by the NACA prior to 1957, and that was summarized in reference 1, was concerned primarily with the design of lateral-control devices having sufficient ... -
NASA-LLIS-1290
Abstract: Description of Driving Event:
The project, which focused on technology demonstration, needed to decide whether to use a full size or scale model aircraft to achieve its research objectives. The decision ...Subject(s) : Aircraft , Risk Management/Assessment , Safety & Mission Assurance , Test Article , -
NACA-RM-L51J04
Abstract: INTRODUCTION
Previous investigations of sweptback wings (see, for example, references 1, 2, and 3) have shown that as the aspect ratio and sweepback are increased, it become increasingly difficult to provide longitudinal ... -
NASA-LLIS-0097
Abstract: Description of Driving Event:
During rotation of the L/H OMS pod (LP04) an O2 meter was heard rolling inside the pod. The pod was being raised to a vertical position per V5016. Also a "light thud" was ...Subject(s) : Flight Equipment , Hardware , Launch Vehicle , Lifting Devices , -
NASA NPD 8710.5 REV D W/CHG 1
Abstract: APPLICABILITY
This NPD applies to NASA Headquarters and NASA Centers, including Component Facilities, and to the Jet Propulsion Laboratory and to other contractors to the extent specified in the ... -
NASA-LLIS-0968
Abstract: Abstract:
Project test deficiencies frequently occur in cost/schedule driven flight instrument developments. Cost/schedule driven, high-risk instrument projects should plan for expanded test programs. ...Subject(s) : ATLO , Flight Equipment , Hardware , integration and test , mission assurance program , Payloads , Policy & Planning , project reserves , risk management , Risk Management/Assessment , Safety & Mission Assurance , tailoring , Test & Verification , test planning , -
NACA-TN-1404
Abstract: INTRODUCTION
One of the problems arising from the increased speed and wing loading of modern airplanes is the difficulty of obtaining high lifts for landing and take-off without impairing lateral control. If conventional ... -
NASA-LLIS-0653
Abstract: Practice:
All wiring harnesses, cables, and wires on payloads, instruments, subsystems, and components are well shielded, including the use of connector types that provide tight EMI back shells or other ... -
NASA-LLIS-1559
Abstract: Abstract:
A senior individual with experience in many space flight projects, including several X-vehicles, has observed that the aerospace industry has changed and there are many indirect costs ...Subject(s) : Procurement , Program and Project Management , Risk Management/Assessment , Small Business & Industrial Relations , -
NASA-LLIS-1430
Abstract: Abstract:
There have been several incidents involving ground-based pressure systems and components that have resulted in "near misses." All of these incidents were the result of systems and/or components ...Subject(s) : Accident Investigation , Facilities , Hardware , Human Factors , Mishap Reporting , Pressure Vessels , Safety & Mission Assurance , -
NACA-RM-H56C20
Abstract: INTRODUCTION
This paper presents an application of the time-vector method of analysis in the determination of static and dynamic lateral derivatives of a 45 swept-wing fighter-type airplane. Details ... -
NASA-LLIS-0406
Abstract: Description of Driving Event:
On Feb. 8, 1996 at 10:04 AM on the B-1 Test Stand, a vent line overpressurization and subsequent rupture occurred. No personnel injuries resulted. Failure damage included ...Subject(s) : Energetic Materials - Explosive/Propellant/Pyrotechnic , Hazardous/Toxic Waste/Materials , Pressure Vessels , -
NACA-TN-778
Abstract: A discussion is given of the important aspects of the stalling of vertical tail surfaces. The type of instability encountered is described and the possibilities of inadvertent occurrence are noted. The influence of directional ... -
NASA-LLIS-0205
Abstract: Description of Driving Event:
The External Tank (ET) hardware incorporates five categories of instrumentation, sensors, and associated cabling, where the instrumentation data is recorded in the orbiter ...Subject(s) : Energetic Materials - Explosive/Propellant/Pyrotechnic , Fire Protection , Hazardous/Toxic Waste/Materials , -
