A NEW LOOK AT SUPERSONIC AIRCRAFT HYDRAULIC REQUIREMENTS

Current estimates of hydraulic power requirements for the S. S. T. indicate that system pressure, fluid temperature and power levels will increase sharply over present jet transports. Initial examination of projected effects of increased fluid temperature on operational life of pumping equipment discloses a life gap existing between present high temperature development and anticipated equipment life for the S. S. T.

Initial comparisons of centralized power generation and distribution are drawn against the design concept of a composite system. The importance of hydraulic power in control of the S. S. T. is discussed and a recommendation presented for earlier attention to the hydraulics area by the ultimate operators of the S. S. T. than has been traditional in the preliminary design phase of transports.
