We describe an aircraft design, which is capable of vertical takeoff and landing and also high-speed cruise on a fixed wing. The aircraft comprises a fuselage with a probe-deployment mechanism, which deploys a sample-gathering probe, located at a front end of the fuselage. A main wing is coupled to a middle section of the fuselage, wherein a right motor and right propeller are coupled to a right side of the main wing, and a left motor and left propeller are coupled to a left side of the main wing. The right and left propellers are angled with respect to the fuselage enabling the aircraft to pitch up to a vertical-takeoff mode and pitch down a horizontal-cruising mode. A pitch motor and pitch propeller are located at the rear end of the fuselage, wherein the pitch propeller is angled to provide substantially vertical thrust to control a pitch of the fuselage.

A flying car that does not require complex transformation between a car and an aircraft, the flying car can quickly take off from a land, such as road or parking, and can land on the road or parking. The flying car is of triangular shape having a broad front and narrow rear. Three motorized members are coupled to three corners of a frame of the flying car. Each of the three motorized members includes a wheel assembly that includes a wheel and a wheel frame, an inner ring and an outer ring coupled to each other, and both mounted to the wheel frame. A fan mounted on the inner ring and one or more turbines mounted on the outer ring.

A system for propulsion management of an electric aircraft. The system includes an electric aircraft that is configured to transition between a hover state and a fixed-wing flight state. The electric aircraft includes at least one set of a plurality of propulsors that are coupled to the electric aircraft. The system includes a flight controller that is coupled to the electric aircraft. The flight controller is configured to detect a state transition of the electric aircraft from the hover state to the fixed-wing flight state. The flight controller is configured to send a parking or unparking command to the at least one set of a plurality of propulsors to reduce air drag.

Various embodiments of a variable geometry quadrotor with a compliant frame are disclosed, which adapts to tight spaces and obstacles by way of passive rotation of its arms.
