Vertical take-off and landing aircraft
A vertical take-off and landing (VTOL) aircraft is disclosed. The VTOL aircraft may include: a fuselage, a thrust rotor to produce a propulsion thrust, rotor booms, canard surfaces, wing surfaces, tail surfaces, and lift rotors to produce lifting thrust force.
1. A vertical take-off and landing (VTOL) aircraft comprising:
a fuselage having a roll axis, the fuselage comprising a tensile stressed skin;
a thrust rotor to produce a propulsion thrust;
first and second rotor booms;
first and second canard surfaces, each of said first and second canard surfaces having a canard proximal end and a canard distal end connected to one of the first rotor boom or the second rotor boom and the fuselage;
first and second wing surfaces, each of said first and second wing surfaces having a wing proximal end and a wing distal end, a wing proximal end of the first wing surface being connected to a first side of the fuselage and a wing proximal end of the second wing surface being connected to a second side of the fuselage opposite the first side of the fuselage;
first and second tail surfaces, each of said first and second tail surfaces having a tail proximal end connected to one of the first and the second rotor booms and a tail distal end spaced apart from a tail distal end of the other tail surface;
a first plurality of lift rotors connected to the first rotor boom and a second plurality of lift rotors connected to the second rotor boom to produce lifting thrust force;
wherein the first and second rotor booms are positioned a distance below a plane defined by the lower surface of the fuselage, wherein the distance is defined by a length of the first and second canard surfaces.
2. The VTOL aircraft of claim 1 , further comprising one or more wheels coupled to the first and second rotor booms.
3. The VTOL aircraft of claim 1 , wherein the first and second rotor booms are configured as pontoons.
4. The VTOL aircraft of claim 1 , wherein the first plurality of lift rotors comprises four lift rotors.
