In 1915, the French company Westinghouse-Leblanc filed a patent for a revolutionary aerial torpedo jet for the time.the jet vision of the French was precocious.from the beginning of the aviation era, a considerable number of interested parties saw further than the propeller and the explosion engine. Thus, Leblanc was aware of the priorities of the war, which meant that artillery should be moved by other means, because in fact a shell can only be directed if it undergoes its technical metamorphosis by becoming a self-propelled projectile, according to Leblanc, and this well before the V1.
The torpedo contains an explosive charge and a fuel reserve, is equipped with bearing surfaces and in the tail section, it has stabilizers and rudders. The rocket engine with nozzle forms an extension of the body. The fuel is a mixture of gasoline and nitrogen tetroxide, both are stored in separate compartments of the body of the torpedo and introduced into the combustion chamber with the help of pumps actuated by an electric motor. A rechargeable battery is provided to power the latter, as well as to activate the gyroscopes used to control the rudders. All the auxiliary mechanisms are located in a separate compartment. In order to avoid a significant displacement of the center of gravity of the torpedo during fuel consumption, the fuel tanks are located symmetrically with respect to the center of gravity.
To give the torpedo its initial speed, a special catapult is used. The torpedo is mounted on a sled which can slide along the ramp. The torpedo, continuing its forward movement by inertia, flies away from the sled. The engine of the rocket begins to function at the time of the departure. For the initial ignition of the fuel, a small charge of gunpowder with slow combustion is placed in the combustion chamber, ignited before the launching of the torpedo. This charge heats a heat insulating jacket inside the chamber, which also serves as an igniter for the liquid fuel supplied to the chamber.It was another bold breakthrough that went unheard on the paths of history. Too often, ideas with great impact do not find a good audience.

Looks a bit too advanced for 1915. Liquid rocket & conical nozzle before Goddard? Gyro autopilot before Sperry? While not totally impossible, such combination of breakthrough ideas from one author is suspicious.
 
That's odd
15 year before they start to build Liquid rocket engine with conical nozzle and Gyro autopilot ?

sadly i could find only little information about Westinghouse-Leblanc company
Seem they were French-US company
allot of their patents ware related to Turbines and one from 1916 looks like primitive Gyro.
Elements needed for such Air Torpedo.

Patent: Method of and means for balancing rotating bodies.
 
Patent-Plan unique.

Indeed, the patent application is dated December 10, 1915, so the work of Leblanc was finalized at that date. The patent is published on May 19, 1920.

The invention of the rocket nozzle is not due to the American Goddard but to the Swede Laval ... in the middle of the XIX century ...
