Vertical take-off and landing aircraft

A vertical take-off and landing aircraft comprising:

• a fuselage;
• at least one propulsion system;
• four lift propellers;
• at least two fixed wing planes, including a main wing plane and a rear wing plane located behind the aircraft;
• wherein:
• the main wing plane and the rear wing plane are both located behind a most forward lift propellers of the lift propellors, and both are located above the lift propellers;
• the main wing plane has a variable span and comprises a pair of wings, each wing being foldable along a lateral axis of the aircraft, such that a movable end part of each wing is positioned along and above a fixed part of the respective wing upon folding;
• the aircraft comprises a control system for varying the span of the main wing plane in flight by unfolding each wing laterally;
• the four lift propellers are distributed on either side of the main wing plane and on either side of the fuselage;
• two of the lift propellers located on a same side of the fuselage are connected to the fixed part of the wing located on the same side of the fuselage and are longitudinally separated by at least a magnitude of a chord of the main wing plane located therebetween;
• and two of the lift propellers located on a same side of the main wing plane are laterally separated by at least a width of the fuselage located therebetween.
