TechXGeek was formed in June 2018 in Montreal, Quebec, Canada, by Casey Wang, Founder, Pierre Guyonnet, Cofounder and James Ngo, Cofounder. The company was found due wanting to moving society forward with advanced air mobility (AAM) for urban and rural passengers and due to the importance of reducing carbon emissions at the same time.
The company is advocating gender equality. TechXGeek is naming each electric vertical takeoff and landing (eVTOL) aircraft model after great women throughout our history. The aircraft on this web page is named Marie, after Marie Curie, a Polish physicist and chemist who was a pioneer researcher on radioactivity and the first woman to win a Nobel Prize.
Marie is an eVTOL (with the option of a hybrid-electric power source) passenger aircraft that holds one pilot and four passengers. The aircraft is also expected to have the option of autonomous flight. The aircraft has eight VTOL propellers and has one pusher propeller for forward and reverse flight. The aircraft has an estimated cruise speed of 160+ km/h (100+ mph), with a range of 150+ km (94+ miles) and has a flight time of 50 minutes.
The aircraft has a box wing configuration with the VTOL propellers on two booms on the top ends of the box wing. The VTOL propellers are positioned in pairs and are contra-rotating propellers. As forward speed increases with the rear pusher propeller, lift is transferred to the box wing allowing the aircraft to have a longer range and flight time through the efficiency of winged flight.
The fuselage of the aircraft is similar to a small helicopter with its tail the height of the top of the fuselage. The pusher propeller is at the rear of the tail and the tail has a horizontal stabilizer with downward facing vertical stabilizers. The landing gear is simplified and has fixed tricycle strut landing gear.
The design of the aircraft reduces the complexity of the aircraft, reduces weight, purchase cost, maintenance cost and increases the safety and reliability of the aircraft.
The cabin is reconfigurable allowing the aircraft to be used in any air mission such as air taxi service, personal transportation, tourism, police, fire, utility, news reporting, air cargo and defense.
Aircraft type: eVTOL or hybrid-electric passenger aircraft
Electric motors: 9 independently controlled electric motors
Power source: Batteries or fuel cell
Fuselage length: 7 m (23 ft)
Overall height: 3 m (10 ft)
Tip-to-tip distance: 10 m (33 ft)
Fuselage: Carbon fiber composite
Windows: Windows allow left, right and forward visibility, for spectacular views with a solid roof above the passenger compartment
Wings: Box wing configuration, with VTOL propellers on a boom which is level with the top of the cabin
Tail: Horizontal stabilizer with downward facing vertical stabilizers.
Landing gear: Fixed strut landing gear
Safety features: Distributed Electric Propulsion (DEP), provides safety through redundancy for its passengers and/or cargo. DEP means having multiple propellers (or ducted fans) and motors on the aircraft so if one or more propellers (ducted fans) or motors fail, the other working propellers (or ducted fans) and motors can safely land the aircraft. There are also redundancies in the sub-systems of the aircraft.
