Ice accretion on flying surfaces affects the aerodynamic performance and handling qualities of the aircraft, and may require different pilot corrective action, dependent upon the surface that ice is accreting onto. The current methodology for ice detection usually relies on an indirect method, normally based on ambient air temperature, and liquid water content. When a pre-set threshold level is reached, the ice protection system is activated, whether or not ice is accreting on critical surfaces. This method is not cost effective or efficient for an ice protection system. Air Conformal Ice Detection obviates these problems by using a ‘direct’ method of detection, local to the critical area being monitored.

There is a need to begin generating data on the testing and performance of high pressure inflatable structures in the space environment. This data is necessary to validate inflatable structures for future space exploration mission studies. The International Space Station can serve as a long term testbed for inflatable structures where multiple samples can be flown and evaluated over a period of several years. Precursor experiments can fly also on Space Shuttle missions to provide preliminary data quickly and economically. This paper describes new, small payload carriers that are being developed commercially for the Space Shuttle. It outlines a range of inflatable structure experiment topics that are suitable for both precursor and long term study.
