Abstract
One embodiment is an aircraft including first and second fuselages; a wing assembly connecting the first and second fuselages, wherein the first and second fuselages are parallel to one another; first and second forward propulsion systems tiltably attached to forward ends of the first and second fuselages; and first and second aft propulsion systems fixedly attached proximate aft ends of the first and second fuselages.
Claims20
An aircraft comprising:
- first and second fuselages;
- a wing assembly connecting the first and second fuselages, wherein the first and second fuselages are parallel to one another;
- first and second forward propulsion systems tiltably attached to forward ends of the first and second fuselages such that the first and second propulsion systems are tiltable between a first orientation in which rotor blades of the first and second forward propulsion systems are disposed above the first and second fuselages and a second orientation in which the rotor blades of the first and second forward propulsion systems are disposed forward of forward ends of the first and second fuselages;
- and
- first and second aft propulsion systems fixedly attached to the first and second fuselages proximate aft ends thereof such that rotor blades of the first and second aft propulsion systems are rotatable in a plane substantially parallel with longitudinal axes of the first and second fuselages, wherein the first and second aft propulsion systems comprise pylons attached directly to upper surfaces of the first and second fuselages.

An electric vertical takeoff and landing aircraft (eVTOL) selectively convertible between a hover mode and a cruise mode, the eVTOL comprising:
- a first fuselage;
- a second fuselage parallel to the first fuselage;
- a wing assembly connecting the first and second fuselages;
- first and second forward propulsion systems attached to forward ends of the first and second fuselages, the first and second forward propulsion systems comprising first and second pylons tiltable relative to the first and second fuselages between a first position when the aircraft is in a hover mode, in which rotor blades of the first and second forward propulsion systems are disposed above the first and second fuselages, and a second position when the aircraft is in a cruise mode, in which the rotor blades of the first and second forward propulsion systems are disposed forward of forward ends of the first and second fuselages, wherein each of the pylons houses a drive system for providing rotational power to rotor assemblies of the forward propulsion systems;
- and
- first and second aft propulsion systems fixedly attached to the first and second fuselages proximate aft ends thereof such that rotor blades of the first and second aft propulsion systems are rotatable in a plane substantially parallel with longitudinal axes of the first and second fuselages, wherein the first and second aft propulsion systems comprise pylons attached directly to upper surfaces of the first and second fuselages.
