This paper describes the development of high speed radial hydraulic piston pumps for aircraft hydraulic systems. Pumps of this type have been designed to operate at appreciably higher speeds for their size than conventional hydraulic pumps. The scaling of pump size to speed is discussed and the operating speeds of different types of pump are compared. The reductions in total aircraft system mass obtainable by running pumps at high speed are outlined since these can be much greater than the direct saving in pump mass. It is concluded that the double row radial pump which is in a relatively early stage of development compared with axial piston pumps, will operate reliably at speeds well in excess of the maximum achievable on equivalent sizes of conventional pump.
