Procedure for designing localized shell and finite difference computer program applications to Saturn V vibration testing project
Mode coupling effect on response of rigid body to random excitation analyzed, using two degree of freedom model
Piggy-back method of packaging integrated circuits will increase packaging density and design flexibility. It will also eliminate interconnection leads between the die and associated inductances, and thus increase the attainable frequency response of the circuit.
Electromagnetic absorption and scattering by contaminants from Apollo spacecraft
FORTRAN computer program for calculating time dependent temperature distribution over planar thin plates with arbitrary distribution of conductive, convective, and radioactive data
Omnidirectional microwave parallel plate broadband antenna for spacecraft communications
Surface integration analysis of radiation pattern of parallel plate waveguide
Radiation emission from circular waveguide aperture imbedded in plane conducting surface solved using variational and iteration methods
Inertial guidance system design for manned space missions, considering environmental and performance requirements and energy minimization

Electrical characteristics of the mesh or screen electrodes used in electron tubes are improved by decreasing the shunt capacitance of the tube while retaining the close spacing needed for the required resolution. Vibrational characteristics are enhanced by raising the natural resonant frequency.
Symmetric parallel plate waveguide reflection coefficient analyzed
Noncavitating and cavitating performance of inducer in liquid hydrogen

Soft, cross-serrated aluminum shims are used as mating gaskets between uneven surfaces. Under pressure, the aluminum flows to conform with surface irregularities, forming a plane of uniform bearing.
Proton sensitivity of films used in ATM satellite missions
Interactions between hypersonic neutral gas beam and orificed pressure gauge in spinning satellite noting dependence on angle of attack
