Programs manual for one-dimensional and two- dimensional steady state models of catalyzed hydrazine decomposition reaction chambers
Computer program computes the total thermal radiation flux on each of a set of exposed surface elements of a spacecraft in the vicinity of a celestial body. The incident flux consists of solar, both direct and planetary-reflected, and planetary-emitted infrared radiation as functions of time.
Computer program computes time history of subsatellite point and visibility from station to given satellite by integrating given epoch state.
Computer program documentation of engineering analysis, decoding, program listing, input and output data display sheets, and computations
Computer program for calculation of single jet and five jet interaction regimes associated with multiple rocket engines
Computer programs developed to simulate the RSECS (representative shuttle environmental control system) are described. These programs were prepared to provide pretest predictions, post-test analysis and real-time problem analysis for RSECS test planning and evaluation. These programs are on a magnetic tape cassette and on a disc device that is part of the WANG-2200 series computer system.
Computer program for computation of chemical equilibrium compositions, rocket performance, and chapman-jouguet detonations
Computer program simplifies and clarifies random noise vibration test results. It also varies PSD test specifications, sets up automatic equalization equipment, and calculates an exact accleration level for the random noise prior to the test.
Computer programs perform landing stability studies of mechanical impact system designs for advanced spacecraft. The programs consider variation in spacecraft vertical and horizontal velocity, attitude and orientation, shock strut load-stroke characteristics, and ground coefficient of friction.
Computer program which determines the mean camber surface required to support a given set of loadings on a composite wing in subsonic compressible flow has been developed.
Computer program for development of planetary atmospheric models for spacecraft design and mission planning applications
Computer program for calculating aircraft sonic boom signatures on ground
Computer program for solving equations governing flow in axial turbines
Computer program reduces the unbalance of weldable half-bridge strain gage installations. The program calculates the two resistance ratios of each half-bridge gage, outputting a table of gages ranked according to resistance ratio. The tabulation forms a convenient record of gage characteristics.
Computer program determines the useful strength of a thin-walled shell once it has been wrinkled. It can be used as an analytical tool by designers to determine how much wrinkling or deformation a shell can withstand when subjected to axial compression and bending loads.
Computer programs for least squares adjustment of satellite observations for simultaneous ranges or directions
Computer program for solar cell performance prediction in spacecraft power supply systems
