Abstract:
1. A flight vehicle, comprising: a flight vehicle central portion having a top, bottom, and left and right sides, wherein the left side is opposite to the right side; a left wing portion extending from the left side of the flight vehicle central portion, and a right wing portion extending from the right side of the flight vehicle central portion, wherein the left wing portion defines a left wing chord line and the right wing portion defines a right wing chord line; a left propeller assembly comprising: a front left propeller rotational axis, wherein the front left propeller comprises at least one propeller blade having a front left propeller blade radius extending from the front left propeller rotational axis to a front left propeller distal blade tip, wherein the front left propeller when rotated about its rotational axis defines a front left propeller rotational disk defined by the rotation of the front left propeller distal blade tip; and a right propeller assembly comprising: a left propeller assembly rotational mechanism comprising a front left pivot point about which the front left propeller support can rotate up and down with respect to the left wing chord line and further comprising a rear left pivot point about which the rear left propeller support can rotate up and down with respect to the left wing chord line, wherein the rear left pivot point is displaced from the front left pivot point, wherein the left propeller assembly rotational mechanism is configured to selectively move the left propeller assembly from the left propeller assembly first configuration to the left propeller assembly second configuration and back to the left propeller assembly first configuration by rotating the front left propeller support about the front left pivot point and by rotating the rear left propeller support about the rear left pivot point; a right propeller assembly rotational mechanism comprising a front right pivot point about which the front right propeller support can rotate UP and down with respect to the right wing chord line and further comprising a rear right pivot point about which the rear right propeller support can rotate up and down with respect to the right wing chord line, wherein the rear right pivot point is displaced from the front right pivot point, wherein the right propeller assembly rotational mechanism is configured to selectively move the right propeller assembly from the right propeller assembly first configuration to the right propeller assembly second configuration and back to the right propeller assembly first configuration by rotating the front right propeller support about the front right pivot point and by rotating the rear right propeller support about the rear right pivot point.
