System and method for flight control of an electric vertical takeoff and landing aircraft

1 . A system, comprising:

a flight component of an electric aircraft;

a pilot control; and

a flight controller communicatively connected to the pilot control and the flight component, the flight controller configured to:

receive a pilot instruction from the pilot control;

determine a minimum safe speed for the electric aircraft;

determine, based at least in part on the pilot instruction and the minimum safe speed, a flight parameter; and

control the flight component based at least in part on the flight parameter and a transition phase of flight, the transition phase of flight comprising a transition between a hover state and a fixed-wing flight state of the electric aircraft.

2 . The system of claim 1 , wherein the flight controller configured to control the flight component comprises the flight controller configured to override the pilot instruction.

3 . The system of claim 1 , wherein the flight component comprises one or more of a control surface, a pusher component, a lift component, or a power source.

4 . The system of claim 1 , wherein the flight controller configured to control the flight component comprises the flight controller configured to implement a corrective action.

5 . The system of claim 1 , wherein the flight controller is configured to control the flight component further based at least in part on one or more of a limit associated with the flight parameter or a limit associated with the flight component.

6 . The system of claim 1 , wherein the flight controller configured to control the flight component comprises the flight controller configured to automatically transition the electric aircraft between the hover state and the fixed-wing flight state.

7 . The system of claim 1 , wherein the pilot instruction comprises an instruction to implement the transition between the hover state and the fixed-wing flight state of the electric aircraft.

8 . A method, comprising:

receiving, at a flight controller of an electric aircraft from a pilot control, a pilot instruction;

determining, at the flight controller, a minimum safe speed for the electric aircraft;

determining, at the flight controller, based least in part on the pilot instruction and the minimum safe speed, a flight parameter; and

controlling, by the flight controller, based least in part on the flight parameter and a transition phase of flight, a flight component of the electric aircraft, the transition phase of flight comprising a transition between a hover state and a fixed-wing flight state of the electric aircraft.

9 . The method of claim 8 , wherein controlling the flight component comprises overriding the pilot instruction.

10 . The method of claim 8 , wherein:

the flight component comprises a pusher component; and

controlling the flight component comprises:

determining that the electric aircraft is in the hover state; and

initiating, by the flight controller, thrust at the pusher component.

11 . The method of claim 8 , wherein:

the flight component comprises a lift component; and

controlling the flight component comprises:

determining that the electric aircraft is in the fixed-wing flight state; and

initiating, by the flight controller, lift at the lift component.

12 . The method of claim 8 , wherein:

the flight component comprises a lift component; and

controlling the flight component comprises:

determining, by the flight controller, that an airspeed velocity of the electric aircraft meets or exceeds the minimum safe speed; and

based at least in part on determining that the airspeed velocity meets or exceeds the minimum safe speed, disengaging, by the flight controller, the lift component.

13 . The method of claim 8 , wherein controlling the flight component comprises automatically controlling at least one of a pusher component of the electric aircraft or a lift component of the electric aircraft.

14 . The method of claim 8 , wherein the flight parameter comprises one or more of:

a lift,

a thrust,

a trajectory,

an altitude,

an airspeed velocity, or

a groundspeed velocity.

15 . An electric aircraft, comprising:

a flight component;

a pilot control; and

a flight controller communicatively connected to the pilot control and the flight component, the flight controller configured to:

receive a pilot instruction from the pilot control;

determine a minimum safe speed for the electric aircraft;

determine, based least in part on the pilot instruction and the minimum safe speed, a flight parameter; and

control the flight component based least in part on the flight parameter and a transition phase of flight, the transition phase of flight comprising a transition between a hover state and a fixed-wing flight state of the electric aircraft.

16 . The electric aircraft of claim 15 , wherein the flight controller configured to control the flight component comprises the flight controller configured to control at least one of a pusher component or a lift component based at least in part on an airspeed velocity of the electric aircraft and the minimum safe speed.

17 . The electric aircraft of claim 15 , wherein the flight controller configured to control the flight component comprises the flight controller configured to control the flight component to automatically transition the electric aircraft between the hover state and the fixed-wing flight state.

18 . The electric aircraft of claim 15 , wherein the flight component comprises one or more of a control surface, a pusher component, a lift component, or a power source.

19 . The electric aircraft of claim 15 , wherein the flight controller configured to control the flight component comprises the flight controller configured to implement a corrective action in response to a failure event.

20 . The electric aircraft of claim 19 , wherein the failure event is one or more of a rotation degradation of a rotor or a reduced torque of a rotor.
