Technical Field

The invention belongs to the technical field of airplane power supply, and particularly relates to a double power supply system of an electric composite wing airplane in one-way parallel connection.

Background

The flight process of the composite wing aircraft comprises vertical take-off and landing and cruise flight, and taking a typical 4+1 type electric composite wing aircraft as an example, 4 vertical motors work simultaneously during vertical take-off and landing, and the required power is very high. When the airplane is switched to a cruising state after taking off, the 4 vertical motors stop working, and only the cruising motors work, so that the airplane needs small power, but needs a battery capacity as large as possible for long-time flight. Because the requirement difference between the two working states is large, and the situation that the battery power is used up and does not have enough power for vertical landing in the cruising process is prevented, two groups of batteries are generally used for respectively supplying power for the vertical motor and the cruising motor, the vertical battery is a high-discharge small-capacity battery, and the cruising battery is a large-capacity battery.

However, the two groups of batteries are completely independent from each other, the vertical battery is only useful in the landing stage, and is completely burden in the cruising flight, so the smaller the vertical battery is, the better the performance is, but much more electric quantity is required to be reserved for the vertical battery to ensure the flight safety compared with the normal flight, the dead weight of the airplane is increased, and when the electric quantity of the vertical battery is insufficient under the unexpected condition, the cruising battery cannot assist the vertical flight even if the electric quantity is full, and therefore, in order to solve the problems, a one-way parallel double power supply system of the electric composite wing airplane is required.

Disclosure of Invention

The invention aims to provide a double power supply system of an electric compound wing aircraft in one-way parallel connection, so as to solve the problems in the background technology.

This setting is used for so cruising the battery can be to the motor power supply that hangs down, nevertheless hangs down the battery and can not be to the motor power supply that cruises, because the electric quantity of the two sets of batteries of aircraft all can support the multiaxis flight, when the long-time multiaxis flight of needs or return voyage appears unexpectedly in the flight process, is difficult for crashing because of the battery electric quantity that hangs down, has improved the security greatly.

Preferably, the hang-up battery and the cruise battery respectively supply power for the hang-up motor and the cruise motor and are connected in parallel through a one-way current element.

The invention has the technical effects and advantages that: the one-way parallel electric compound wing aircraft dual-power supply system,

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

The invention provides a one-way parallel electric composite wing aircraft dual-power supply system as shown in figure 1, which comprises a vertical battery and a cruise battery, wherein current output ends of the vertical battery are respectively and electrically connected with current input ends of four vertical motors through leads, a current output end of the cruise battery is electrically connected with a current input end of the cruise motor through a lead, one pole of the cruise battery is connected with one pole of the vertical battery in parallel, and the other pole of the cruise battery is connected with the other pole of the vertical battery in parallel in a one-way mode through a one-way current element.

Specifically, the vertical battery and the cruise battery respectively supply power to the vertical motor and the cruise motor and are connected in parallel through a one-way current element.

Example two

The invention provides a battery pack in one-way parallel connection as shown in fig. 2, namely, after a single vertical electric core and a single cruising electric core are in one-way parallel connection, the single vertical electric core and the single cruising electric core are respectively connected in series, after the electric cores 1 are connected in series, power is supplied to a cruising motor, after the electric cores 2 are connected in series, power is supplied to the vertical electric motor, because current can flow from the electric cores 1 to the electric cores 2, a charging balance head is led out from the end of the electric cores 1, the whole battery pack can be charged, and two. The battery pack with the one-way parallel effect, namely the one-way parallel double-power-supply battery pack is formed.

Specifically, the vertical battery cell 1 and the battery cell 2 are connected in parallel in one direction and then connected in series to form a battery pack.

The unidirectional parallel double-power-supply battery pack is improved on the basis that a 4+1 type electric composite wing aircraft is taken as an example, a cruise battery supplies power to a cruise motor, and a vertical battery supplies power to four vertical motors, so that the cruise battery can supply power to the vertical motors, but the vertical battery cannot supply power to the cruise motor; in the vertical takeoff stage, the drooping battery and the cruising battery supply power for the four drooping motors together, the power consumption of the drooping battery is very low during takeoff, when the airplane is switched to cruise flight, the electric quantity of the drooping battery cannot be reduced during cruise due to the fact that the vertical battery cannot supply power to the cruising motor due to the limitation of the one-way current element, and when the airplane lands vertically, the drooping battery and the cruising motor supply power for the drooping motor together.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
