METHOD OF THE CONFIRMATION OF THE INTRABALLISTIC ENERGY AND CHARACTERISTICS OF THE SOLID-PROPELLANT CHARGE OF THE SPECIAL JET PROPULSION UNIT AND BENCH DEVICE

摘要

1. A method for verification intraballistic and energy characteristics of the solid rocket motor charge special purposes, comprising burning a series of charges with different rates of combustion chamber-simulator with feed circular opening of the critical section with the pressure in the metering chamber, the simulator, characterized in that the charge before combustion thermostated to a temperature providing charge burning rate and pressure in the engine with minimum deviations from their nominal values ​​and the determined n formula: where t- temperature thermostating charge before firing bench test (BID) t- maximum operating temperature range; t- lowest temperature range of operation - the burning velocity of the charge in a particular party, a certain constant pressure in the device (PDP); u- maximum speed charge combustion at a maximum temperature over the operating range; u- minimum speed charge combustion at a minimum temperature in the range ekspluatatsii.2. Stand device for confirmation intraballistic and energetic characteristics of the solid charge rocket engine for special purposes, comprising a metal jig with a horizontal rotary plate for mounting simulator chamber with feed circular opening of the critical section, a pressure measuring sensor in a camera simulator, siloizmeritelej between the rotary plate and slipway, characterized in that the jig has a vertical stop wall, which is fastened to the bracket with the bearing assembly for vertical swinging plate shaft ceiling elements, fastened siloizmeritelej n
