Abstract
In order to generate an efficient aerodynamic braking force, whatever the speed of a vehicle such as an airplane flying in the air, the method includes a step for the production of energy by the vehicle, a step of storage of the energy produced and a step of utilization of such energy to drive a propeller which generates a force opposing the forward motion of the vehicle. Energy is produced by using the displacement of the vehicle with respect to air using a propeller driving a generator, or using the displacement with respect to the ground, using wheels driving a generator, or using generators driven by motors of the vehicle. The energy can be stored in the pneumatic, electric or kinetic form and the generation and driving means are selected according to the technology used for the storage means.
Claims8
An aerodynamic braking device for an aircraft including:
- a first aircraft mounted means that produces energy,
- a second aircraft mounted means that stores the energy generated by said first means, and
- third aircraft mounted means that generates an aerodynamic force to brake the aircraft from the energy stored in said second means, with said first means including at least one propeller able to be driven in rotation by the relative displacement of the aircraft with respect to the air surrounding the aircraft, said at least one propeller being coupled to at least one compressor that compresses a gas to be stored in the second means, the gas including air sampled from air surrounding the aircraft;
- wherein the third means includes said at least one propeller, said at least one propeller including blades that are positioned with their axes substantially parallel to a rotation axis of said at least one propeller when said device is not in use.
