Say hello to Robert Maddox, or the Rocketman, in this video he is showing off his custom propane-powered pulsejet kart. With four pounds of liquid propane, Maddox can hit speeds of up to 90 miles per hour on asphalt.
It runs on propane and diesel fuel and has a top speed of 60 mph, this advanced Pulsejet kart featuring Instant staring with injected propane and injected diesel. In the vodeo we can see where the engine glows devil red behind him and a propane tank and he steers with one hand filming himself with the other.
Its small wheels make it perfect to tackle the Bonneville Salt Flats in Utah.The kart has a complete throttle range, and Bob has driven it up to 90 mph.
The video doesn’t offer much information on the build, but then again, there isn’t much to it. Pulsejet engines are characterized by simplicity, low cost of construction, and high noise levels. While the thrust-to-weight ratio is excellent, thrust specific fuel consumption is very poor.
The pulsejet uses the Lenoir cycle, which, lacking an external compressive driver such as the Otto cycle’s piston, or the Brayton cycle’s compression turbine, drives compression with acoustic resonance in a tube. This limits the maximum pre-combustion pressure ratio, to around 1.2 to 1./wikipedia
