INTERMITTENT BLOWOFF TYPE AIR TUNNEL TESTER

摘要

PURPOSE:To prevent breakage caused by passage of an impact wave at a startup, by identifying the completion of the startup of an air tunnel to automatically charge a sample model into a measuring shell. CONSTITUTION:A sample model 1 is housed into a housing box 2 when an air tunnel is started. When the completion of the startup of the air tunnel is identified by a startup judging means having a signal of a pressure detector 7 as input, an actuator 5 pushes a support metal 3 through a push rod 6 to slide a mounting metal 3 until the sample model 1 reaches a specified position in a measuring shell. Then, the support metal 3 is fixed at a specified position with the push rod 6 and a guide roller 4.
