Thermophysical properties of working fluids and tube, header, and fin materials and compatibility analysis for design of space electric power radiator-condenser systems
Flow field analysis over blunt axisymmetric body in perfect gas or equilibrium air using method of integral relations
A program which accepts a system model in the form of Boolean equations and solves these equations using a ternary algebra will determine the response of large combinational and sequencial switching circuits to given input changes, taking into account malfunctions due to races, hazards, and oscillations.
Solutions for the axially symmetric motion of an elastic spherical sandwich shell have been obtained from a theory of shells which includes the effects of transverse shear deformation and rotary inertia. Frequency equations and mode shapes are derived for the full vibrations of a closed spherical shell.
Program analyzes the consequences of a loss-of-flow accident in the primary cooling system of a heterogeneous light-water moderated and cooled nuclear reactor. It produces a temperature matrix 36 x 41 /x,y/ which includes fuel surface temperatures relative to the time the pump power was lost.
Dynamic Analysis Program, FORTRAN 4 Level H /DAP4H/, developed from 27 subprograms, features liberal use of the subroutines, subprograms, and skeletonization to minimize programming effort in formulating models of new systems and components. It formulates mathematical models of complex mechanical, pneumatic, and hydraulic dynamic systems.
FORTRAN 4 program /P1-GAS/ calculates the P-O and P-1 transfer matrices for neutron moderation in a monatomic gas. The equations used are based on the conditions that there is isotropic scattering in the center-of-mass coordinate system, the scattering cross section is constant, and the target nuclear velocities satisfy a Maxwellian distribution.
Analytical procedure and Fortran IV program for determining off-design performance of multistage axial flow turbines
Fortran IV program for calculating orbital heating rates to various-shaped satellites in general trajectory
Program designs the feed system geometry and the subreflector surface, with the main reflector configuration and frequency of operation as input data. Although the feedhorn is not designed, its required gain, beamwidth, and approximate radiation pattern are specified.
Computerized simulation of mission profiles for inertial navigation of low thrust spacecraft in both heliocentric transfer and planetocentric spiral
FORTRAN 4 program for computerized design of two dimensional supersonic nozzles with sharp edged throats
Operating manual for FORTRAN program to predict aerodynamic and heat transfer characteristics of annular and rectangular gas turbine combustors
Network Analysis for Systems Application Program /NASAP/ applicable in analysis and design of solid state circuits
Electron probe microanalyses in metallurgy and geology performed by FORTRAN program
Systems design of digital computer real-time control system, and interface hardware for early launch laser tracking system
