Abstract

This invention is about a set of common features that will characterize any machine of the new type to be produced within the set of pumps, turbines and blowers. The machines in this new category, as will be here described, will be told apart from those already in use by one main peculiarity. They will feature a stationary (non-rotating) axle for the rotation of the impeller around it but the impeller will be a solid part of the housing which will be the rotating part. Firmly, on or through the hollow core of the axle, ducts will be fitted for the intake and discharge of the powering or pumped fluid. So the housing of the machine will deliver or receive power from the body in which it will be incorporated or connected (that is torque times angular velocity). An implementation of this invention is shown in the accompanying drawings. Here the rim of a wheel of an aircraft is the rotating body. Part of the rim will serve as the housing (containing shell) of an air-driven turbine (or pump as the case may be). Accordingly, the normal stationary hub of the (formerly idle) wheel will serve as the axle of rotation for the impeller born by the rotating housing. This turbine within the rim will be powered by compressed air from the fuselage to make torque for prespinning the wheel just before touchdown. During landing, this air may be redirected to the brakes for early cooling. The rim already transformed into an air-driven turbine can be utilized to taxi or pull-out the aircraft without a tractor. In this case the turbine of this invention can be made as a two-stage regenerative machine. Research on the capabilities of the just invented turbine at the phase of development will determine the feasibility of taxiing without the main engines at least partially, using pneumatic power from the Auxiliary Power Unit.
