SRM Safety relay modules for high-performance turbofan engines assuring safe shutdown as well as access protection of test facilities.
Turbofan engines are checked for function and performance after completion of a major overhaul.
During test maximum operating conditions are reached.
In order to insure safety during testing, all access to the
test facility is locked and monitored. Safeguards remain active during a malfunction or until safe system shutdown is achieved.
