This invention relates to apparatus used for obtaining a propulsion effect from the combustion of a mixture of fuel and air or other oxidizing agent. More specifically, the invention relates to apparatus in which the propelling effect is produced by the discharge of the products of combustion through a nozzle extending rearward in the line of flight or of gas discharge. It is the object of my invention to provide apparatus by the use of which a very dilute fuel mixture may be utilized and by which it may be more effectively consumed in the combustion chamber. Another object is to provide a propulsion apparatus in which the admission and firing of the propelling mixture is automatically effected by the pressure developed by the relative movement between the apparatus and the surrounding atmosphere. An important feature of the invention relates to the provision of apparatus effective to supply a richer mixture at the discharge end of the combustion chamber and a thinner mixture toward the opposite end of the chamber. I also provide auxiliary containers within the chamber, adapted to contain a relatively rich mixture throughout the length of the chamber. It is also an object of my invention to provide means for regulating the fuel supply in accordance with the mass of air entering the combustion chamber, taking into account both its density and its relative velocity.
