Welding clamps, placed inside and outside a rocket case, hold it in proper alignment during tungsten inert gas welding. These metal blocks, connected by a stainless steel band, eliminate the need for backup bars.
Critical inclination theory of earth satellites - extension to case of asymmetrical potential of main body
Jacobi integral and the elliptic case of the restricted problem of three bodies, and study of the remote history of the earth-moon system
Critical inclination of close earth satellites for case of asymmetrical potential of main body and small eccentricity - peculiar libration
Model of peripheral auditory system - case study in neural modeling
Aluminum carrying case protects charts during transit and opens to form a rigid easel for their presentation. Looseleaf clamps hold the charts in place for both carrying and displaying them.
Convergence bounds and rates for extended compound estimation problem in sequence case
Computer aids for worst case electronic circuit design
General planetary perturbation computation for resonance cases
Rotor design to evaluate outer case blowing or bleeding of single stage axial flow compressor
Matrix-Holzer analyses for predicting free vibration modes of clustered launch vehicle configurations including Titan IIIC and uncoupled Saturn I cases
Construction of Lyapunov function for case of stability with constantly acting disturbances in nonlinear spaces
An investigation of the incompatibility of titanium in certain grades of nitrogen tetroxide will be discussed as a case history. The methodology used in its resolution will point out some of the dangers associate with compatibility testing. The methodology also will present some of the difficulties associated with coordinating an investigation involving many contractors and U. S. Government agencies. The techniques employed in this investigation are described in considerable detail for the benefit of investigators with similar problems.
Exact solutions for vibrations of hollow elastic cylinder bonded to thin casing of different material
Fabrication, nondestructive testing, and hydrostatic pressure testing of 260 SL-1 case
Injection moldable polymers suitable for use in heat sterilizable battery cases
Control system design and analysis, and survey of case histories involving spacecraft dynamic interaction
Finite slump strains in vertical long hollow elastic cylinder externally case bonded to elastic tank related to solid propellant rocket storage
