[0002] eVTOL (electric Vertical Take-off and Landing) is an electric vertical take-off and landing aircraft. As an aircraft capable of vertical take-off and landing, eVTOL is unrestricted by terrain and runway conditions, making it an extremely convenient and fast means of medium- and short-distance transportation.

The manual operation control device is arranged next to the pilot and does not need to be used under normal flight conditions. The corresponding action is performed through the manual operation control device only when the relevant backup execution components need to be activated.

[0040] Combine Figure 3As shown, the generator and battery pack are electrically connected to corresponding electrical components.

[0043] Based on the above embodiments, it can be seen that the redundant safety operation control system of the hybrid eVTOL adopts multiple redundant safety designs to solve the safety issues of various single-point catastrophic failures. By using multiple sensors, it can warn of potential dangers caused by various improper operations and eliminate hidden dangers. It can realize the full-scale, multi-level catastrophic failure state detection of the eVTOL and provide backup plans, providing maximum safety protection for drivers and passengers.

[0044] In one embodiment, a redundant safety operation control method for a hybrid electric VTOL is provided. The method adopts the redundant safety operation control system for the hybrid electric VTOL in the previous embodiment. The method includes:

[0045] (1) When the engine-driven generator fails to power the eVTOL, the alarm sounds an insufficient power alarm, and the backup battery pack automatically provides sufficient power to allow the eVTOL to continue to fly safely for an appropriate time or distance and land safely. The alarm can be a combination of sound and screen flashing display.

[0046] (2) When the rotor drive motor fails, the alarm sounds a fault alarm, and the pilot starts the propeller drive motor. Otherwise, the central controller issues a command to start the propeller drive motor, so that the eVTOL continues to fly safely in fixed-wing aircraft mode and taxis to land on the airport runway; or when the propeller drive motor fails, the alarm sounds a fault alarm, and the pilot starts the rotor drive motor. Otherwise, the central controller issues a command to start the rotor drive motor, so that the eVTOL continues to fly safely in helicopter mode for an appropriate time or distance and lands safely.

[0047] The rotor drive motor and propeller drive motor are two different power units in the eVTOL configuration. The rotor drive motor drives the rotor, while the propeller drive motor drives the propeller. These are used for eVTOL ascent and descent, respectively. However, as long as one motor is functioning properly, the eVTOL's safety is guaranteed. The rotor drive motor and propeller drive motor are isolated from each other in terms of installation and control, eliminating any conflicts.

[0048] (3) When the rudder actuator fails, the alarm sounds an alarm and the propeller drive motor is controlled to maintain the directional control of the eVTOL; when the pitch rudder actuator fails, the alarm sounds an alarm and the propeller drive motor is controlled to maintain the pitch control of the eVTOL; when the flaperon actuator fails, the alarm sounds an alarm and the propeller drive motor is controlled to maintain the roll control of the eVTOL.

[0049] The rudder actuator and directional control propeller drive motor are two different devices for controlling flight direction on an eVTOL. They can be used interchangeably, with the rudder actuator being the primary device. Similarly, the pitch rudder actuator and pitch control propeller drive motor are two different devices for controlling flight pitch on an eVTOL. They can be used interchangeably, with the pitch rudder actuator being the primary device. The flaperon actuator and roll control propeller drive motor are two different devices for controlling flight roll amplitude on an eVTOL. They can be used interchangeably, with the flaperon actuator being the primary device.

[0050] (4) When the flight direction sensor detects that the eVTOL's flight direction deviates from the preset direction, the alarm will sound a direction deviation alarm, and the pilot will correct the flight direction or set a new flight direction. If the pilot does not perform any flight direction operation, the central controller will issue a command to automatically correct the flight direction deviation. The flight direction sensor set here detects deviation from the preset direction, and by setting the pilot to control and the central controller to automatically issue commands, the accuracy and safety of the flight direction are effectively guaranteed.

[0051] (5) When the pitch angle sensor detects that the eVTOL's pitch angle deviates from the preset angle, the alarm will sound a pitch angle deviation alarm, and the pilot will correct the pitch angle or set a new pitch angle. If the pilot does not perform any pitch angle operation, the central controller will issue a command to automatically correct the pitch angle deviation. The pitch angle sensor set here detects that the pitch angle deviates from the preset value. By setting the pilot to control and the central controller to automatically issue commands, the accuracy and safety of the flight pitch angle are effectively guaranteed.

[0052] (6) When the roll angle sensor detects that the eVTOL's roll angle deviates from the preset angle, the alarm will sound a roll angle deviation alarm, and the pilot will correct the roll angle or set a new roll angle. If the pilot does not perform a roll operation, the central controller will issue a command to automatically correct the roll angle deviation. The roll angle sensor set here detects that the roll angle deviates from the preset value. By setting the pilot to control and the central controller to automatically issue commands, the accuracy and safety of the flight roll angle are effectively guaranteed.

[0053] (7) When the flight altitude sensor detects that the eVTOL's flight altitude deviates from the preset altitude, the alarm will sound a flight altitude deviation alarm, and the driver will correct the flight altitude or set a new flight altitude. If the driver does not perform any flight altitude operation, the central controller will issue a command to automatically correct the flight altitude deviation. The flight altitude sensor set here detects that the flight altitude deviates from the preset value. By setting the driver to control and the central controller to automatically issue commands, the accuracy and safety of the flight altitude are effectively guaranteed.

[0054] (8) When the maneuvering overload acceleration sensor detects that the eVTOL's maneuvering overload deviates from the preset overload, the alarm will sound an overload deviation alarm, and the pilot will correct the aircraft's maneuvering overload deviation or set a new maneuvering overload limit. If the pilot does not perform the maneuvering overload correction operation, the central controller will issue a command to automatically correct the maneuvering overload deviation. The overload acceleration sensor set here senses the overload deviation from the preset value, and by setting the pilot control and the central controller automatically issuing commands, the accuracy and safety of flight overload judgment are effectively guaranteed.

[0055] (9) When the wing angle of attack sensor detects that the eVTOL's wing angle of attack deviates from the preset angle of attack limit, the alarm will sound a wing angle of attack deviation alarm, and the pilot will correct the wing angle of attack deviation; if the pilot does not perform the wing angle of attack correction operation, the central controller will issue a command to automatically correct the wing angle of attack deviation. The wing angle of attack sensor set here detects the deviation from the preset angle, and by setting the pilot control and the central controller automatically issuing commands, the accuracy and safety of the flight wing angle of attack are effectively guaranteed.

[0056] (10) When the collision avoidance sensor detects a collision risk with the eVTOL, the alarm sounds a collision hazard warning, and the pilot controls the eVTOL to perform a collision avoidance maneuver. If the pilot fails to perform a collision avoidance maneuver, the central controller issues a command, and the eVTOL automatically performs a collision avoidance maneuver. When the collision avoidance sensor detects a collision risk, the pilot controls the flight, and the central controller automatically issues a command, effectively ensuring flight accuracy and safety.

[0057] (11) When all backup devices fail and the eVTOL cannot continue to fly safely, the alarm will sound a reminder to "activate the entire aircraft parachute". The pilot will activate the parachute ejector to release the entire aircraft parachute. The central controller can also automatically activate the parachute ejector to release the entire aircraft parachute according to the preset settings. The parachute ejector set here is the last safety guarantee for the entire aircraft. It will not be used easily. It will only be activated when all backup plans fail. The entire aircraft parachute set also effectively guarantees flight safety. Even if all failures occur, it can provide the last safety guarantee. It is particularly suitable for relatively small aircraft such as eVTOL.

[0058] Based on the above embodiments, it can be seen that the redundant safety operation control method of the hybrid eVTOL adopts multiple redundant safety designs to solve the safety issues of various single-point catastrophic failures. By using multiple sensors, it can warn of potential dangers caused by various improper operations and eliminate hidden dangers. It can realize the detection of all-round, multi-level catastrophic failure states of eVTOL and provide backup plans. For single-point catastrophic failures, there are redundant backup devices to ensure safe flight, and it can tolerate most double-fault and multiple-fault combinations. It can also automatically correct safety issues caused by some incorrect operations, providing maximum safety protection for drivers and passengers.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
