 Spath Engineering has been involved with two projects testing turbine engines. Both involved LOX augmentaion of turbine engines with the purpose of developing an improved platform for flight launched rockets. |
|
| Images below show a Jet Engine research facility built by Spath Engineering in partnership with MSE Technology Applications of Butte, Montana and ATK-GASL of Ronkonkoma, New York for the Defense Advanced Research Projects Agency. Innovative techniques were applied to a General Electric J85-5 and Pratt and Whitney F100-200 to extend their Mach number range. | |
F100-200 installed in the test position.  |
Mass Injection Pre-Compressor Cooling system mounted on the inlet duct for the F100-200.  |
Close-up of the F100-200 mounted on the test stand.  |
F100 running augmented (afterburning) at Mojave test site.  |

Video of an internal view of the afterburner in operation taken with the water-cooled tailpipe camera. The flashing prior to afterburner lightoff is the igniter plug. The turbine starts to glow as military power is selected just prior to afterburner lightoff. |
|
This photo shows the water-cooled tailpipe camera that is able to internally image the afterburner combustion. The gas in the plume impinging on the camera probe is around 3,200° F.  |
