SOLID-PROPELLANT ROCKET ENGINE HOUSING, AND CASE-BONDED CHARGE Russian patent published in 2012 - IPC F02K9/34 

FIELD: engines and pumps.

SUBSTANCE: solid-propellant rocket engine housing includes pressure shell comprising front and rear bottoms, rear flange, front cover and internal thermal protective coating. In the latter of rear bottom there arranged is cuff attached to the bottom on its maximum and smaller diameters. On cuff there made is annular edge line the generatrix of which is located at an angle to generatrix of thermal protective coating surface. Surface of thermal protective coating between edge line and hole of rear flange is coated with anti-adhesive material, for example, fluoroplastic film. The other invention of the group refers to case-bonded charge containing the above solid-propellant rocket engine housing and the charge attached to thermal protective coating of the housing, the flaming surface of which is formed with central blind channel. Open edge forming additional part of flaming surface is made on the charge, and diameter of open edge that is not attached to thermal protective coating exceeds the diameter of rear flange hole. Edge line of cuff is implemented into the charge.

EFFECT: inventions allow simplifying the design of solid-propellant rocket engine housing and case-bonded charge, as well as reducing the weight of solid-propellant rocket engine housing and improving reliability of case-bonded charge.
