Abstract: Description of Driving Event:
The KSC work control documentation system, which controls and records space shuttle processing, has evolved from three manned space flight programs: Mercury, Gemini, and ...Subject(s) : Administration/Organization , Configuration Management , -
NACA-TN-605
Abstract: A theory has been deduced for the "rotation noise" from a propeller with blades of symmetrical section about the chord line and set at zero blade angle. Owing to the limitation of the theory, the equations give without ... -
NASA NPD 9741.1 REV B
Abstract: APPLICABILITY
This NPD is applicable to NASA Headquarters and NASA Centers, including Component Facilities. -

Abstract: Description of Driving Event:
Funding cuts threaten the viability of the orbital debris project.Subject(s) : Aerospace Safety Advisory Panel , Financial Management , Policy & Planning , Risk Management/Assessment , Safety & Mission Assurance , -
NASA-LLIS-0833
Abstract: Practice:
Simulate on-orbit space maintenance activities by using a neutral buoyancy facility to assist in making design decisions that will ensure optimum on-orbit maintainability of space hardware. -
NACA-TN-3783
Abstract: Available theories and test data on buckling of curved plates and shells are reviewed. For torsion and external-pressure loadings, the test data are correlated in terms of linear buckling theories for both the elastic and ...Subject(s) : AXIAL COMPRESSION LOADS , BENDING , BUCKLING , CIRCULAR CYLINDERS , COMPRESSIVE STRENGTH , CYLINDRICAL BODIES , DYNAMIC STRUCTURAL ANALYSIS , HANDBOOKS , LOADS (FORCES) , PLASTIC DEFORMATION , PLATES (STRUCTURAL MEMBERS) , SHEAR STRENGTH , SHELLS (STRUCTURAL FORMS) , STRUCTURAL STABILITY , TORSION , -
NASA-LLIS-0045
Abstract: Description of Driving Event:
The geography of KSC facilities does not lend itself to ease of team unity. The launch control center control rooms, from which systems engineers conduct tests, are a ...Subject(s) : Administration/Organization , Communication Systems , Configuration Management , Facilities , Human Resources & Education , Industrial Operations , -
NACA-WR-L-464
Abstract: Wind-tunnel tests have been made to investigate the possibility of reducing the hinge moments of a control surface by beveling the trailing edge. The tests were made with a 9-percent-thick airfoil having a 30-percent-chord ... -
NASA-LLIS-0982
Abstract: Description of Driving Event
Effective, critical traceability of EEE parts may be lost if original shipping containers and documentation are not retained by original equipment manufacturers (OEMs) and ...Subject(s) : Aircraft , Configuration Management , Flight Equipment , Ground Equipment , Hardware , Logistics , Packaging Handling Storage , Parts Materials & Processes , Procurement Small Business & Industrial Relations , Risk Management/Assessment , Safety & Mission Assurance , -
NASA-LLIS-0591
Abstract: Abstract:
Two satellites with different propulsion system designs were lost in 1993 and 1994 when blow-by from pyrovalves interacted violently with propellants. To prevent detonation of fuel due to the ...Subject(s) : Energetic Materials - Explosive/Propellant/Pyrotechnic , Hardware , -
NASA-LLIS-1433
Abstract: Abstract:
To avoid team leadership and public image concerns, NASA should recognize that it will not be the lead public investigative entity in a human space flight mishap.Subject(s) : Accident Investigation , Administration/Organization , External Relations , NASA Standards , Policy & Planning , Safety & Mission Assurance , -
NASA-LLIS-0872
Abstract: Description of Driving Event:
On January 4, 1995, at approximately 8:50 a.m., two technicians at WSTF were overcome and collapsed from breathing in an oxygen deficient atmosphere that formed during ...Subject(s) : Cryogenic Systems , Emergency Preparedness , Environment , Facilities , Ground Equipment , Ground Operations , Hazardous/Toxic Waste/Materials , Packaging Handling Storage , Personal Protective Equipment , Policy & Planning , Research & Development , Risk Management/Assessment , Safety & Mission Assurance , Test Facility , -
NACA-TN-1766
Abstract: An investigation has been made of a powered model of a single propeller low-wing airplane with three values of tail length and three horizontal tails to determine the effects of tail length and tail volume on the longitudinal ... -

Abstract: Abstract:
Instead of using commercial off-the-shelf (COTS) equipment to replace the ground instrumentation data acquisition system (Permanent Measurement System [PMS]), NASA and its contractor designed ...Subject(s) : Acquisition / procurement strategy and planning , Business processes , Crew operations and support concepts , Engineering design and project processes and standards , Entry Systems , Ground Equipment , Ground Operations , Ground support systems , Long term sustainability and maintenance planning , Test & Verification , -
NASA-LLIS-0165
Abstract: Description of Driving Event:
The orbiter heat shield must be lifted through the rear of the swing platforms on platform 10 (coordinate X0=17.37, Y0=20.00). A structural diagonal is in the way and could ...Subject(s) : Facilities , Ground Operations , -
NACA-TM-851
Abstract: In the following report a complete theory of twisting failure by the energy method is developed, based on substantially the same assumptions as those employed by Wagner and Bleich. Problems treated in detail are: the stress ... -
NASA-LLIS-1188
Abstract: Description of Driving Event:
During routine maintenance, employees discovered a telephone junction box under a raised flooring area that was sparking and smoking. An investigative team has determined ...Subject(s) : Communication Systems , Configuration Management , Energy , Facilities , Fire Protection , Flight Equipment , Ground Equipment , Hardware , Industrial Operations , Information Technology/Systems , Payloads , Spacecraft , Test & Verification , Test Article , Test Facility , -
