Serving the Military, Aerospace, and Industrial Industries
Model 854301: F-15 Speed Calibration Test Stand
The Chant Engineering Model 854301 Speed Calibration Test Stand is designed and manufactured by Chant Engineering’s to verify the F-15 secondary power system governors and switches that are being dynamically calibrated.
In use, the operator mounts the switch to the mounting flange, selects the proper operating speed for the preset selector panel and starts the test.The switch is accelerated at a certain speed for a pre-programmed amount of time then decelerated at a specific rate and time. This procedure is cycled for the predetermined time frame per the Governments technical order.
During this test the switch is supposed to actuate within certain speed ranges. Pass-fail is displayed on the digital readout for each test. This test stand will test the F-15 two-speed switch assembly for the jet fuel starter, the Governor switch for the central gearbox and the Governor switch for the F-100 AMAD gearbox.

Model 836801: Fatigue Cycle and Static Shaft
The Chant Engineering Model 836801 Test Stand is used to dynamically and static test power take-off shafts for Aerospace and Military customers. One test dynamically fatigues the shaft and one test is for the static torque. The fatigue test stand rotates the two shafts simultaneously at 25,000 rpm for approximately 24 hours per test.
The high-speed rotating portion of the test stand is located in a protected test cell while the operators’ control station is located outside, for operator safety. After testing, the shaft is examined for cracking or damage.
The static test stand is used to tortionally test the shaft. In use, the operator mounts the shaft to the test stand sets the amount of torque and the pneumatic actuator rotates one end of the shaft while the other end is fixed. The torque is measured via an electronic torque cell and displayed on the digital readout.

Some tests require manual intervention, in which case the test program will stop and advise the operator to perform the next step. The program will resume when prompted by the operator. All test conditions are pre-set in a password protected computer file, which will also allow for future test conditions to be programmed if required. All test results are measured and displayed during a test, with the data stored for print out or for future reference. Test results can be printed to any network or printer and may also be searched by several features such as date, product, operator or other features yet to be defined.
The test setup is controlled from a computer, supplied as part of the test stand. The computer is programmed using National Instrument’s LabVIEW programming language.
