PUSHER
Document Type and Number:
Japanese Patent JPS63120842
Kind Code:
A
Abstract:
A propulsion device includes a rocket casing 8 having a combustor chamber 64 with a combustor liner 52 and a nozzle throat chamber 62 with a nozzle throat liner 52; a fuel passageway 56 defined between the liners and an outerwall 54 and a plurality of vanes 80 disposed in the fuel passageway to direct fuel circumferentially whereby the fuel travels a longer path through the passageway, and the residence time of fuel in the passageway is increased to promote heat transfer to the fuel. A plurality of fuel injection holes 68 in the combustor liner are also arranged so that fuel is injected into the combustion chamber in a direction which promotes circumferential motion of the fuel. An oxidizer is introduced through oxidizer injection holes 66 at the center of the combustion chamber to inject oxidizer into the combustion chamber in a direction which promotes circumferential motion of the oxidizer. The fuel injection holes and oxidizer injection holes may be staggered to promote overlapping of fuel and oxidizer and further promote mixing prior to and during combustion. Details are given concerning the nature of the fuel and other propellant components, and catalyst assisted endothermic pyrolysis of the fuel in the passage way is referred to. Details are also given concerning the construction of the rocket casing walls and propellant storage tanks (Fig. 2) and the arrangement of tanks and rocket motors in a vehicle (Fig. 1). Use of the device in a ram-jet or scram-jet is also referred to.
