Best Practice : Control Dynamics Laboratory
The McDonnell Douglas Aerospace (MDA)-St. Louis Control Dynamics Laboratory has constructed a test fixture to conduct a variety of test programs on aircraft hydraulic and flight control systems. Known as the Iron Bird, the steel structure is used to conduct test of actual flight worthy hydraulic systems and flight control actuators under controlled conditions in response to inputs from flight control computers installed on test benches. This system is used for initial component development, system development, and test. It is also used to solve problems which develop in mature systems.
A unique feature of the F-15 Iron Bird is that it is presently configured to support both F-15E and Short Take-Off and Landing (STOL)/Maneuvering Technology Demonstration Programs. A series of manual valves are used to connect system unique components to the hydraulic system. Flight controls, flight control computers, and data acquisition systems are located in adjacent rooms. The ease of transition permits different configurations to be run on successive shifts.
