The UH-1H helicopter icing flight test program: An overview

An ongoing joint NASA/Army program to study the effects of ice accretion on unprotected helicopter rotor aerodynamic performance is discussed. This program integrates flight testing, wind tunnel testing, and analytical modeling. Results are discussed for helicopter flight testing in the Canadian NRC hover spray rig facility to measure rotor aero performance degradation and document rotor ice accretion characteristics. The results of dry wind tunnel testing of airfoil sections with artificial ice accretions and predictions of rotor performance degradation using available rotor performance codes and the wind tunnel data are presented. An alternative approach to conducting future helicopter icing flight programs is discussed.

The Small Astronomy Satellite program - An overview.

The Small Astronomy Satellite (SAS) program sponsored by NASA provides for a series of satellites that can be used for various astronomy experiments. The SAS-A mission is to map the X-ray sources in the entire sky. In addition, discrete X-ray sources are being observed for intensity fluctuations in the range from 1 to 20 keV. The structure design, power system, attitude control and detection system, command system, telemetering system and the testing criteria for the spacecraft are discussed. The SAS-A was launched December 12, 1970, and has been very successful in its scientific mission.
