Flared sonic end nozzle velocity coupling test burner

摘要

A flared sonic end nozzle velocity coupling test burner having a body, the walls of which define a chamber. The chamber is closed at one end thereof and has a flared sonic nozzle at the other end. Tests are performed for determining velocity coupling response with a propellant driver located adjacent to the closed end of the chamber and the propellant sample being situated during a first test at approximately the quarter length position and during the second test at approximately the three quarter length position.
