June, 1911-Accepted, 17th Aug., 1911 PROVISORIAL SPECIFICATION I, LUDWIG WITTGENSTEIN, of Wilmslow Road, Fallowfield, City of Manchester, Researching Student, do hereby declare the nature of this invention to be as follows: This invention relates to propellers for aeroplanes, helicopters, dirigible balloons, or other forms of aerial machines. It consists essentially of a radially armed motor each arm carrying a combustion chamber, and exhaust nozzle at its extremity and each arm formed as, or fitted with, a propeller blade. In carrying out the invention the motor is consturcted with two or more arms radiating from a central hub. Each arm of the motor is tubular with a combustion chamber at or near the extremity. The arm is provided with a passage for air, and a second passage for gaseous, or vaporised fuel, or an injector by which such fuel is admitted. Each combustion chamber is provided with an exhaust nozzle placed at a right angle or other suitable inclination to the longitudinal axis of the arm. The air and fuel are admitted to the arms of the motor, at or near the hub, which may also be fitted with non-return valves, or with suitable admission or inlet valves by which the admission of air and gas can be controlled and regulated. Two or more of the arms are formed with a screw blade or propeller so that each of these arms of the motor also act as propeller blades. Air ist admitted at the hub, and is forced along the arm to the combustion chamber and therein compressed by the centrifugal force exerted by the revolving arms. The gaseous or vaproised fuel is ignited within the combustion chamber where the air ist expanded and the waste gases and products of combustion issue with considerable force through the exhaust nozzles rotating the apparatus at a high velocity. Any other form of radial motor may be constructed with screw or propeller blades forming part of or attached to the radial motor arms. J. OWDEN O'BRIEN Successor to and late of W.P. Thompson & Co, of Manchester, Patent Agents COMPLETE SPECIFICATION. Improvements in Propellers applicable for Aerial Machines. I, LUDWIG WITTGENSTEIN, of Palatine Road, West Didsbury, Manchester, County of Lancaster, late of Wilmslow Road, Fallowfield, City of Manchester, Research Engineering Student, do hereby declare the nature of this invention and in what manner the same is to be performed, to be particularly decribed and ascertained in and by the following statement:- This invention relates to propellers for aeroplanes, helicopters, dirigible ballons, or other forms of aerial machines. It consitst essentially of a radially armed motor each arm carrying a combustion chamber, and exhaust nozzle at its extremity and each arm formed as or fitted with, a propeller blade. The invention will be fully described with reference to the accompanying drawings forming prt of the specification. Fig. 1. Side elevation Fig. 2. Longitudinal section Fig. 3. Section in linie x-x Fig. 1. Fig. 4. Longitudinal section through a modification of the invention. The motor is constructed with two arms A radiating from a central hub B. The arms A are tubular and each arm is provided at the end with a combustion chamber C. The central hub B is provided with an inlet pipe a for gaseous or vapourised fuel and an inlet a1 for air, the inlet pipe a is connected to the pipe a2 which serves to convey the gaseous fuel to the combustion chamber C, and the air passes to combustion chamber in the passage a3 formed between the pipe a2 and the walls of the arm A. The pipe a2 may either extend the whole length of the arm A as shown in Fig. 4. or it may only extend a short distance along the arm as shown in Fig. 2. In the latter case the velocity of the gas and air is sufficient to prevent combustion until they reach the combustion chamber. Or the gaseous fuel may be admitted by an injector. The air and gas inlets a and a1 are preverably provided with non- return valves (not shown) or with suitable admission or inlet valves so that the admission of air and gas can be controlled and regulated. Each combustion chamber C is provided with an exhaust nozzle c. The exhaust nozzles c are shown in the drawings at right angels to the longitudinal axis of the arms A but may if desired be placed at any other angle thereto to give a more effective result. The arms A (although shown flat in Figs. 2 and e) are formed with a screw blade or propeller of any desired shape or pitch so that each of the arms of the motor also acts as a propeller blade. The motor instead of being constructed with only two arms may have any number any or all of which are in the form of a screw blade or propeller. The air and gas admitted at the hub is forced along the arms A to the combustion chambers C and therein compressed by the centrifugal force exerted by the revolving arms, and ignited. The expansion due to the ignition of the mixture within the combustion chamber causes the products of combustion to issue with considerable force through the exhaust nozzles and to rotate the apparatus to a high velocity. Any other form of radial motor may be constructed with screw or propeller blades forming part of or attached to the radial motor arms. Haiving now particularly described and ascertaines the natur of my said invention and in what manner the same is to be performed. I declare that what I claim is: - 1. A radially armed motor in which the arms are formed as or fitted with screw or propeller blades and carry at their extremities a combustion chamber provided with an exhaust nozzle substantially as described. 2. A radially armed motor in which each arm is formed as or fitted with a propeller made hollow and provided with passages or pipes whereby air and gaseous or vapourized fuel may be conveyed to the combustion chamber at the end thereof in which the air and gas are ignited and the expanded products of combustion expelled therefrom for the purpose of rotating the apparatus substantially as described. 3. A radially armed motor in which the arms are formed as or fitted with screw or propeller blades as a whole substantially as described with reference to the accompanying drawings.
