Page 4 College Station, Texas Wednesday, March 24, 1971 THE BATTAUC 1 IHE 8- Camp Student studies gas turbine as engine for lunar rovet ( A power unit that could fur nish efficient mechanical energy and water as a by-product has been investigated by an A&M student for use on the moon. Frankie D. Allen of Amarillo studied the gas turbine as a pos sible engine for a lunar rover. A turbine operates by direct ing a stream of hot gases against the blading of a turbine rotor. It offers the advantages of an in ternal combustion engine with out the complicated mechanics of piston-type reciprocating motion. Allen said that present moon power requirements are satisfied by fuel cells and nuclear power, both having advantages for the particular jobs to which they are applied. With man making repeated moon landings and approaching the point of longer lunar stay- times, Allen said, new fields of technology need to be opened to supply his needs, among them motive power over the lunar sur face and usable water. “By using hydrogen as the fuel and an oxygen oxidizer, the tur bine would produce a gallon of water per hour for living purpose use,” Allen, a senior aerospace engineering major, said. His figures are based on a 15 horsepower gas turbine engine, which he calculated would be suf ficient to drive a 600-pound rover (100 pounds moon weight) over traversable lunar terrain. Allen noted in a, report on his study to Dr. Charles A. Roden- berger that the hydrogen-oxygen combination has several advan tages, including water produc tion, high specific fuel consump tion and liquifying action of both fuel and oxidizer for easy trans portation. The axial flow turbine, em ployed primarily in aircraft en gines, is most widely used« present. Turbine efficiency increais with higher operating temper, tures. Current metals technoluj limits extreme temperatures, Allen employs a porous turtis blade through which coolant be pumped.
