Abstract
Disclosed are methods, systems, and non-transitory computer-readable medium for controlling an automatic descent of a vehicle. For instance, the method may include: determining whether a descent trigger condition is present; and in response to determining the descent trigger condition is present, performing an automatic descent process. The automatic descent process may include: obtaining clearance data from an on-board system of the vehicle; generating a descent plan based on the clearance data, the descent plan including a supersonic-to-subsonic transition and/or a supersonic-descent to a target altitude; and generating actuator instructions to a control the vehicle to descend to the target altitude based on the descent plan.

A method for controlling a supersonic-to-subsonic transition of a vehicle, the method comprising:
- obtaining clearance data from an on-board system of the vehicle;
- generating a descent plan based on the clearance data, the descent plan including a supersonic-to-subsonic transition and/or a supersonic-descent to a target altitude;
- generating actuator instructions to a control the vehicle to descend to the target altitude based on the descent plan;
- based on the clearance data, determining:
- a supersonic-to-subsonic transition and/or a supersonic-descent to a target altitude;
- a descent maneuver;
- and a location of a sonic boom for the descent maneuver;
- and
- based on the supersonic-to-subsonic transition and/or the supersonic-descent to the target altitude and the location of the sonic boom, generating actuator instructions to control the vehicle to automatically execute the descent maneuver.
A method for controlling a supersonic-to-subsonic transition of a vehicle, the method comprising:
- obtaining clearance data including one or more of:
- population data indicating population density or distribution;
- terrain data indicating an altitude of ground level from sea level;
- weather data indicating three-dimensional regions of weather and/or predicted weather;
- and/or supersonic flight restrictions;
- generating a descent plan based on the clearance data, the descent plan including a supersonic-to-subsonic transition and/or a supersonic-descent to a target altitude;
- and
- generating actuator instructions to control the vehicle to descend to the target altitude based on the descent plan.
A method for controlling a supersonic-to-subsonic transition of a vehicle, the method comprising:
- receiving sensor data including safety data comprising one or more values;
- determining whether one of the one or more values exceeds a safety threshold value;
- upon determining that one of the one or more values exceeds the safety threshold value, obtaining clearance data including one or more of:
- population data indicating population density or distribution;
- terrain data indicating an altitude of ground level from sea level;
- weather data indicating three-dimensional regions of weather and/or predicted weather;
- and/or supersonic flight restrictions;
- based on the clearance data, determining:
- a descent maneuver based on center of gravity information and drag information for the vehicle;
- and a location of a sonic boom for the descent maneuver;
- and
- based on the descent maneuver and the location of the sonic boom, generating actuator instructions to control the vehicle to automatically execute the descent maneuver.
