VTOL aircraft having multiple wing planforms

An aircraft having multiple wing planforms, the aircraft comprising:

• an airframe having first and second half-wings with first and second pylons extending therebetween, the first half-wing having a wing section with a partial airfoil cross-section and the second half-wing having a wing section with a partial airfoil cross-section;
• a distributed thrust array attached to the airframe, the thrust array including two propulsion assemblies coupled to the first half-wing and two propulsion assemblies coupled to the second half-wing;
• and
• a flight control system coupled to the airframe, the flight control system configured to independently control each of the propulsion assemblies;
• wherein, the aircraft is configured to convert between thrust-borne lift in a VTOL orientation and wing-borne lift in a forward flight orientation;
• wherein, in the VTOL orientation, the distributed thrust array has a quadcopter configuration;
• wherein, in the forward flight orientation, the first and second half-wings have a biplane configuration in a first planform with the thrust array configured as a two-dimensional thrust array;
• wherein, in the forward flight orientation, the first and second half-wings have a monoplane configuration in a second planform in which the partial airfoil cross-section of the first half-wing mates with the partial airfoil cross-section of the second half-wing to form a full airfoil cross-section and with the thrust array configured as a one-dimensional thrust array;
• and
• wherein, the flight control system is configured to convert the first and second half-wings between the first and second planforms during forward flight.
