A propulsion system coupled to a vehicle. The system includes a diffusing structure and a conduit portion configured to introduce to the diffusing structure through a passage a primary fluid produced by the vehicle. The passage is defined by a wall, and the diffusing structure comprises a terminal end configured to provide egress from the system for the introduced primary fluid. A constricting element is disposed adjacent the wall. An actuating apparatus is coupled to the constricting element and is configured to urge the constricting element toward the wall, thereby reducing the cross-sectional area of the passage.

A personal propulsion device, including a platform, first and second sensors coupled to the platform to measure at least one of a force or pressure exerted by first and second feet; a first thrust system coupled to the platform to provide thrust in a first direction; a second thrust system coupled to the platform to provide thrust in a second direction that is substantially perpendicular to the first direction; and a controller configured to (i) calculate a difference between a measurement by the first sensor and a measurement by the second sensor, and (ii) adjust an output of the second thrust system based at least in part on the calculated difference.

Exhaust redirecting devices are described that are suitable for use in tilt rotor aircraft. Such devices are constructed of light weight material and permit redirection of exhaust gases from turbojet engines of tilt rotor aircraft as nacelles of the aircraft transition between vertical and horizontal flight. Use of a controller permits coordination between exhaust redirection and nacelle position.

This aircraft without wings is designed to allow unmanned flight to any place on earth by simplified construction. This is accomplished by turning the gas turbine engine upward, by means of a geodesic flight organizer, by air mass cooling, and because of its massive amount of power. The VTOL aircraft is never detained by looking for a runway. A conventional jet aircraft needs a long runway to go fast enough for takeoff speed. That's why airports are so big, because conventional jet planes sometimes have to take off at 200 miles per hour for lift. This aircraft shoots straight upwards and then the horizontal stabilizers are turned on. The small-sized box or barrel goes anywhere you want it to go. The aircraft is designed to allow unmanned flight to any place that has air, or the gas of another planet. The aircraft is guided by using a geodesic flight organizer and a gyro. The air mass is split so part goes to the combustion chamber and the other part goes to the thruster for oxygen power. This airplane goes straight up from anywhere, quickly. And the VTOL flight is not exposed to finding a runway, anywhere. The unmanned aircraft will be used to send medical equipment or emergency fire-fighting apparatus, or any other material as needed.
