Fixed wing aircraft with trailing rotors
An aircraft includes a main wing (where the main wing is a fixed wing) and a main wing rotor that extends outward on a trailing edge side of the main wing. The aircraft also includes a truncated fuselage, a canard and a canard rotor that is attached to the canard. The aircraft flies at least some of the time using aerodynamic lift acting on the main wing and flies at least some of the time by airflow produced by the main wing rotor. The aircraft is able to fly in those manners because the main wing rotor and the canard rotor are both fixed rotors, each with an axis of rotation that is tilted downward from horizontal at an angle between 20° to 40°, inclusive.
1. An aircraft, comprising:
a main wing, wherein the main wing is a fixed wing;
a main wing rotor that extends outward on a trailing edge side of the main wing, wherein:
the aircraft is kept at least partially airborne at least some of the time by aerodynamic lift acting on the main wing; and
the aircraft is kept at least partially airborne at least some of the time by airflow produced by the main wing rotor;
a truncated fuselage;
a canard; and
a canard rotor that is attached to the canard, wherein the main wing rotor and the canard rotor are both fixed rotors, each with an axis of rotation that is tilted downward from horizontal at an angle between 20° to 40°, inclusive.
2. The aircraft recited in claim 1 , wherein the aircraft has a total of two canard rotors and a total of six main wing rotors.
3. The aircraft recited in claim 1 , wherein the main wing is a forward swept and tapered wing.
4. The aircraft recited in claim 1 , wherein the aircraft includes:
a total of two canard rotors that are attached to the canard at a first height; and
a total of six main wing rotors that are attached to the trailing edge of the main wing at a second height that is higher than the first height.
5. The aircraft recited in claim 1 , wherein:
the main wing is a forward swept and tapered wing; and
the aircraft includes:
a total of two canard rotors that are attached to the canard at a first height;
a total of six main wing rotors that are attached to the trailing edge of the main wing at a second height that is higher than the first height; and
a V tail.
6. The aircraft recited in claim 1 , wherein:
the main wing is a tapered wing; and
the aircraft includes:
a total of two canard rotors that are attached to the canard at a first height;
a total of six main wing rotors that are attached to the trailing edge of the main wing at a second height that is higher than the first height; and
a three-airfoil tail.
