A compilation of spacecraft loads data from four Titan Centaur Launch Vehicle flights. Volume 1: Acoustics data

The payloads carried by the first four Titan Centaur launch vehicle flights were, a Viking spacecraft dynamic simulator, the Helios A spacecraft, and the two Viking spacecraft. Dynamic loads data were accumulated from these four flights for application to the Viking spacecraft. The accoustics data include time histories and spectral analysis plots of accoustic pressure measurements made in the Centaur and payload compartment during launch flight. Summary plots are presented to show composite spectra for liftoff and Mach 1/Max Q periods of flight

Flight Flutter Testing of the P6M

On the P6M the shake behavior, i.e., the response to random excitation at subcritical speeds of lowly damped airplane modes, is as important as the actual flutter speed. The approach is to first study the problem by means of analyses and wind-tunnel tests. These predictions are compared with flight test data obtained by spectral analysis of tape recordings of the airplane vibration responses to random aerodynamic turbulence. A similar spectrum analysis approach was used in high speed wind-tunnel tests. A resonance excitation technique was developed for low speed wind-tunnel testing, and well defined V-g curves were obtained. The effect of various parameters on both shake and flutter of T-tails with and without dihedral were studied. Preliminary flight tests yielded good correlation; they also yielded interesting information concerning a low frequency transonic snaking mode, and excitation by shed vortices
