Definitions
- the present invention relates to an electric power chain with hybrid power for single-propeller aircraft.
- power chain we mean all of the components that supply or transmit power to the propeller.
- hybrid power we mean a particular combination of energy sources that will provide power to the power chain.
- single-propeller airplane it is meant an airplane intended to carry a number of passengers between one and six passengers depending on the confi gurations.
- the invention proposes, as a hybrid power supply, a power supply combination by 1- photo voltaic panels 2 - electric batteries 3 - Combustion engine supplying an electric generator.
- the fuel to the combustion engine is preferably made from vegetable oil with hydrogen doping.
- the power chain is redundant to give the necessary safety to passengers.
- the power chain is designed to limit power losses and to distribute power in an optimized manner according to the different phases of flight.
- a main object of the invention is to provide a power chain which combines two essential qualities 1 - Optimum safety with in particular the abundance of key components 2 - Optimum power efficiency in order to maximize flight time and increase the payload carried.
- An object of the invention is to provide an aircraft which can be industrialized and which can be mass-produced. Typically a range of 1 to 6 seat single-propeller airplanes could be developed in series with the present invention.
- An object of the invention is to provide a control unit for the pilot which allows, with the greatest possible security, to alternate the operation of the chain of power if ever one of the components fails and to operate automatically and / or manually on its redundant component.
- the invention combines the choice of component, and the architecture of an on-board control electronics which makes it possible to control with total safety both the various failure configurations and an optimization of the efficiency of the chain. power by routing the power flows according to the various flight and / or parking parameters in real time.
- a main feature of the invention being to propose a double hybridization of power supply, namely at least three different energy sources to be combined and made to coexist according to all the stages of life, to provide the necessary power to the motors while offering safety. optimal which is not endangered by this addition of energy source input. Indeed, no solution of the prior art provides a double hybridization solution, which has the advantage of being optimal for the preservation of natural resources, from an ecological and sustainable development perspective.
- FIG.l shows a complete diagram of the power chain.
- FIG.l is a complete diagram of the power chain which logically comprises five stages.
- a first stage is that of the energy supplied. This energy is then converted in a second stage in the power circuit into electrical energy.
- This energy can be the sun which feeds the photovoltaic panels (14), the electric energy which feeds the batteries (12) to make them store energy, or a heat engine (01) which feeds an electric generator (11). .
- the batteries (12) are preferably two in number. They are powered before the flight at the hangar level and in the outdoor parking lot by solar energy. During flight, take-off, cruise or light descent, they are powered by photovoltaic panels (14) and the electric generator.
- the safety threshold parameters can be configured at the level of the on-board electronics.
- the batteries (12) can themselves also power the circuit. We therefore understand that they act as a buffer that can either store energy or release it.
- the entire call distribution or current distribution flow is then regulated on a third stage by means of regulators (26, 29). Namely a first said left regulator (26) and a second said right regulator (29).
- the regulators are redundant and are activated by the pilot by means of respective dedicated commands (36, 39).
- the regulators include on-board software that manages the distribution of energy flows according to flight conditions. Namely, these flows all converge towards a so-called star bus which makes it possible on a node (28) to route the flows according to the request.
- the energy producers that are the batteries (12), the photovoltaic panel (14) and the electric generator (11), beyond this node (28) of the star bus on the fourth stage we find the two engine power control electronics (31 , 34) with a first so-called left power control electronics (31) which controls a first propeller motor (41) and a second so-called right power control electronics (34) which powers a second propeller motor (44). ).
- the pilot has engine power levers (37, 38) which act on the input parameters of the engine power electronics (31, 34).
- the engine power levers (37,38) allow, according to the accepted expression to put the throttle, in this case, for the present to regulate the sending of electric power in the electric motors (41, 44).
- the two levers (37, 38) are connected by a mechanical key which makes it possible or not to actuate the two levers at the same time; The actuation or not of the motors being done by the means either of the regulator commands (36, 39), or by another dedicated means.
- the electric traction motors are actuated only by the power levers (37, 38).
- the two motors (41, 44) are mounted in series on a shaft to drive the propeller (50).
- one motor takes over the other with an operator command which activates one of the two motors.
- This solution is a redundancy solution on a critical part and makes it possible to take over with the second engine if the first one breaks down.
- Note several other essential components are redundant including batteries (12) and regulators (26, 29).
- the present can be applied to a twin engine version with double propeller, namely either according to two different motorized axes, a propeller on each of the wings or in the same axis, a propeller with the front of the fuselage and a propeller at the rear of the fuselage.
- the mass production of the aircraft will be able to operate on conventional fuel, diesel, gasoline, kerosene, or aviation gasoline.
- the present invention therefore relates to a power supply chain for single-propeller aircraft characterized in that upstream the power chain comprises a supply stage with batteries (12), photovoltaic panels (14) and an electric generator (11) whose flow is regulated by left and right regulators (26, 29) which drives a star bus node (28) which feeds downstream a propulsion stage with left power control electronics and straight line (31, 34) which supplies a first motor (41) and a second motor (44) mounted on the propeller shaft (50) of the airplane, the pilot of the airplane activates by an action on its dashboard the regulator controls (36, 39) to give the hand to one of the two regulators whose on-board electronics will control the respective flow entering and / or leaving the components of the supply stage in function of the flight parameters.
- the present invention therefore relates to an electric power supply chain for a single-propeller aircraft characterized in that the electric generator (11) is supplied by a combustion engine (01) supplied with a vegetable oil fuel added to '' hydrogen doping
