Abstract
A jet-powered sled has a body having a control cockpit with control apparatus for an operator to control the jet sled, a set of surface runners adapted to engage a surface upon which the sled is operated, the surface runners removably engaged to spindles coupled to swing arms coupled to the jet sled, and an engine compartment having a jet engine removably mounted in a manner to direct thrust to a rear of the jet sled to propel the jet sled. The jet sled is characterized in that the sled may be adapted specifically to run on water, ice, or snow by installing runners adapted for water, ice, or snow on the spindles of the swing arms.
Claims18
A method of sledding over a variety of surfaces on a sled, comprising:
- mounting a sled body on a first set of swing arms for use on ice and water, and mounting the sled body on a second set of swing arms for use on snow;
- removably installing a jet engine in an engine compartment in the sled body, the engine compartment having a thrust port with angularly adjustable vanes;
- interchangeably mounting onto the sled body one of three sets of runners, including a first set of runners to support the body on ice, a second set of runners to support the body on snow, and a third set of runners to support the body on water;
- interchangeably mounting onto the sled body one of multiple brake assemblies, the brake assemblies having different braking structures from one another and the one brake assembly being chosen depending on the type of surface being sled upon;
- directing thrust from the jet engine through the thrust port to propel the sled forwardly;
- and then steering the sled by a driver in a cockpit of the sled pivoting the vanes about vertical axes.
A method of modifying a jet sled for use on various surfaces, comprising:
- installing a first set of runners and a first set of brakes for use on ice;
- and alternatively,
- installing a second set of runners and a second set of brakes for use on snow;
- and alternatively, installing a third set of runners and the second set of brakes for use on water;
- providing controls for engaging and disengaging the installed sets of brakes to and from the ice, snow, and water, respectively;
- adjusting distance between a body of the sled and the surface by interchanging a first short set of swing arms for a second tall set of swing arms, the swing arms residing between the body and the runners, depending on whether the surface is ice, water, or snow.
