TEST APPARATUS FOR DEVELOPING POGO SUPPRESSION DEVICE

摘要

PURPOSE: A device for inspecting a pogo suppression device is provided to generate a pressure perturbation inside fluid by using a vibrator and to control amplitude by using an amplitude controlling valve. CONSTITUTION: A device for inspecting a pogo suppression device comprises a bend pipe(1), a main pipe(2), a vibrator(3), and an amplitude controlling valve(4). The bend pipe is connected to a fluid storing tank(7) and simulates a resonance frequency of a projectile. The bend pipe is connected to one side of the main pipe and simulates a propellant supplying main pipe of a propulsion system of the projectile. The vibrator is installed in a pipe connected to the other side of the main pipe and generates a pressure perturbation to fluid by controlling an area of a flow path of the pipe. The amplitude controlling valve is installed in a bypass pipe(22) connected to the pipe to be detoured a portion of the pipe where the vibrator is installed. The amplitude controlling valve controls amplitude of the amplitude controlling valve.
