Vertical takeoff and landing aircraft

A vertical takeoff and landing aircraft, comprising:

• an airframe comprising a wing having an airfoil, the airfoil having an airfoil chord line and the wing having a wingspan;
• at least one forward thrust rotor having:
• a horizontal thrust offset angle defined between the airfoil chord line and an axis of rotation of the forward thrust rotor;
• and
• a forward rotor pitch angle defined between a plane of rotation of the forward thrust rotor and a forward thrust rotor blade chord line at a point midway between the axis of rotation of the forward thrust rotor and a tip of a forward thrust rotor blade;
• a plurality of vertical thrust rotors, each of the plurality of vertical thrust rotors having:
• a vertical thrust offset angle defined between the airfoil chord line and a plane of rotation of the vertical thrust rotor, wherein the vertical thrust offset angle is between 3 degrees and 10 degrees;
• a vertical rotor pitch angle defined between the plane of rotation of the vertical thrust rotor and a vertical thrust rotor chord line at a point midway between an axis of rotation of the vertical thrust rotor and a tip of a vertical thrust rotor blade, wherein the vertical rotor pitch angle is less than the forward rotor pitch angle and the plurality of vertical thrust rotors have fixed pitch rotors such that the vertical rotor pitch angle is not adjustable during flight;
• and
• wherein the axis of rotation of the forward thrust rotor and planes of rotation of the plurality of vertical thrust rotors define a plurality of relative thrust angles that are each less than the horizontal thrust offset angle, and
• axes of rotation of the plurality of vertical thrust rotors are spaced apart at distances between 25% and 75% of the wingspan.
