The Hornet Project.
The following is a brief review of the "Hornet Project". The core of the Hornet is a converted combustor can from a Rolls-Royce Dart turboprop engine. The idea was to create a powerful hot air blowing device with no moving parts that could be used for snow removal and ice melting on the railway. The Hornet uses diesel fuel and a standard rental air compressor rather than an exotic aircraft turbine as the prime mover.
Here is the back end of the combustor. Note the pressure gauge on top of the air casing. The Hornet is securely mounted and anchored to the floor, it produces around 300 lbs of thrust at full power. The small black hydraulic hose is the fuel line.
The sound this thing makes is deafening. I have heard a lot of things in my life, but nothing like this. The ignition exciter is the small silver box in the foreground. Notice the CO2 fire extinguisher, we always keep one handy incase we blow a fuel line or something.
The "YF-22" Nozzle.
Check out this video of the Hornet in operation.
The huge volume of smoke followed by a bang and burst of thrust is produced by injecting unburned fuel into the hot combustor then igniting it with the spark igniter.
Here is a narrated video describing the Hornet's construction:
