Pulse Jet Powered Helicopter

In other rotor tip jet propelled helicopters, it is common to provide a jet engine at the tip or outboard end of each rotor blade. The reaction of the jet causes rotation of the rotor with consequent flight of the craft; with no other power being required. A disadvantage is that with the jet engine at the tip of the rotor, considerable drag occurs as a result of the presence of the jet engine.

This Jet Powered Helicopter uses a special arrangement in which a pulse jet engine is located at the root or inboard end of the rotor structure adjacent the rotor column to simplify the fuel flow problem and obviate the objectionable drag which would otherwise occur with the jet engine at the tip of the rotor. In the construction of this helicopter, the jet engine at the root end of the rotor, uses a relatively long tail pipe forming part of. the engine; and the tail piping is utilized to provide a main spar structure for the rotor and providing the exhaust for the jet engine. The rotor structure provides a simple and light but yet sturdy construction. Because of the relatively long tail piping of the jet engine, quieter operation results compared with a jet motor at the wing tip. The hot gases passing through such tail piping eliminate any icing problems which may otherwise occur under certain conditions of flight. Drawings and instructions.  ....more

The personal air transport is capable of taking off and landing vertically (VTOL) as well as hovering, forward and back as well as side to side, and is capable of traveling forward at a reasonable speed. It requires a minimum of energy to remain airborne, and which is exceedingly safe to fly, simple and easy to control and easy to operate. By providing a stable, shrouded platform with engines distributed around a circle with each engine arranged to provide upward thrust along a vertical axis. It can retain its stable orientation and continue to fly even in the event of an engine failure. An aircraft weight of 225 pounds and a full tank of fuel the craft will be able to lift a payload of about 400 pounds. The aircraft is a nimble flyer which can rapidly rise off the ground and fly horizontally in any desired direction. Control is effected in two ways:

(1) Small moveable paddles which enable the craft to rotate about its central vertical axis under control of the operator, and

(2) Throttle control, thus controlling the engine speed which will cause the craft to rise, fall or hover. The speed of the engines are also controlled separately to cause the craft to tilt in any desired direction and to move horizontally. Drawings and instructions.  ....more

Vertical Take-Off Flying Platform

This one man platform is a true VTOL flying machine, it's driven by a ducted fan to lift a man into free flight. It is different from a surface skimming hovercraft in that it can reach a considerably higher altitudes. Its driven by a pair of coaxial, counter-rotating propellers inside a six foot diameter duct. The duct gives the fans greater efficiency than unshrouded propellers having greater diameter. Originally developed and built for the U.S. Army and Navy in their VTOL research programs. Drawings and instructions.  ....more

PVTO381..........................$10.00

This is one of the most unusual aircraft ever, it has no propeller, no jets, no helicopter rotors, no wings, in fact it has no moving parts at all. It needs no runway, takes off vertically, and will fly in any direction like a helicopter. This 2 foot diameter model takes to the air completely unsupported and flies on pure electricity. Lift is produced when a negative charge from the emitter changes surrounding air particles into ions, the ions rush toward the positively charged grid, causing a down flow of air, keeping the aircraft aloft. It can be built in almost any shape, it doesn't matter, but round models are the most easily maneuverable.  ....more

In the thermo jet engine a unique system is provided where gas jets work in conjunction with a jet to compress the air; the impelling jet resulting from the high velocity of the primary fuel supply. This power plant system is dependent upon, a thermochemical jet process, thus the name "thermo-jet". The thermo jet uses a primary air-injection nozzle in combination with a pilot burner, in  which  fuel is combined with air sufficient to sustain its own continuous combustion. This combustion process is a heat transfer cycle, which is utilized to furnish most of the energy to compress air for the main fuel combustion, eliminating the need for an expensive mechanical compressor. As a power plant the thermojet engine provides for rugged, economical and reliable operation, as no moving parts are required. It burns liquid fuel, such as propane, gasoline, kerosene, alcohol, etc.,  with a high degree of combustion efficiency, because of the ideal fuel-air ratios. The thermo jet engine is a power plant ideally suited for installation on the rotor tips of  helicopters; having the advantage of self-starting , efficient operation, being capable of developing static thrust under stationary conditions, and also has economical fuel consumption at varying speeds and altitudes.

HOW to DESIGN & BUILD SMALL LIQUID-FUEL ROCKET ENGINES

The rocket engine is a relatively simple device in which propellants are burned and the resulting high pressure gases are expanded through a specially shaped nozzle to produce thrust. Gas pressurized propellant tanks and simple propellant flow controls make operation of a small liquid-fuel rocket engine about as simple as operating an automobile engine. Why then do so many amateur rocket engines fail or cause injury? The reason, usually and simply, is that the amateur is not accustomed to high pressure devices operating near material temperature limits. His normal everyday life is, instead, filled with devices and gadgets operating at low pressures and at low thermal energy levels. With proper design, careful workmanship, and good test equipment, operated in a safe manner, the amateur can build small, liquid-fuel rocket engines which will have hours of safe operating life. This will provide you with design information, fabrication procedures, test equipement requirements, and safe oeprating procedures for small liquid-fuel rocket engines, so you can build your own liquid fuel rocket.
