Russian engineer and inventor Dahir Semenov, also known as Dahir Kurmanbievich Semenov, has a long track record of imaginative and occasionally terrifying, visions of future technology. His company name, Dahir Insaat, is Turkish for Dahir Construction and was founded in 2006. The Fire Fighting Rescue electric vertical takeoff and landing (eVTOL) and ground vehicle one of his most intriguing designs, and is part of a larger number of ideas for gyroscopic vehicles. Semenov has designed a multitude of concepts from buildings, to ground vehicles, trains, eVTOL aircraft and more.

Dahir Insaat's OrQuad Rail is an eVTOL airliner concept design and is generically called a "flying train" by its inventor because it has a unique design where the aircraft flies above a stationary electrified rail with a long power chord trailing from behind the aircraft to the rail. Using electricity from a rail to power the aircraft, allows a large airliner type aircraft to fly with zero emissions. While there is no mention about the capacity of this aircraft, the aircraft appears to be a high capacity airliner with multiple desks, based on several other high capacity eVTOL airliner designs which have already been published by the inventor. The aircraft hypothetically could hold in the range of 2,000-3,000 passengers and crew.

The OrQuad Rail airliner is a multicopter design with four large ducted fans located on the corners of the aircraft, each fan unit holding two sets of propellers. Looking at the graphic of the aircraft, the ducted fans also rotate independently on an axis to maneuver the aircraft as needed. Each propeller can spin independently of each other for additional control of the aircraft while in flight.

A unique feature of the aircraft includes skylights on the roof of the top deck providing a luxurious ambience for both passengers and crew. In addition, the OrQuad Rail fuselage has an untraditional seven-sided shaped fuselage (almost a rectangular shaped fuselage) with no tail or rudder.

The aircraft is designed to land on the roof of an airport-type terminal and passengers enter and exit the aircraft in the open air, without the use of an enclosed jetway (officially called a passenger boarding bridge). For landing, the aircraft most likely has retractable wheeled quadricycle landing gear. Because the aircraft is a multicopter without wings, it would need a much larger power supply than aircraft using wings for lift. Virtually limitless power will be supplied to the aircraft by an umbilical chord attached to the aircraft and then the other end of the power chord is connected to a wheeled-truck which runs along the stationary powered rail.

The company is looking for investors to begin building the aircraft, terminals and the power rail system.

Specifications:

• Aircraft type: eVTOL high capacity aircraft
• Piloting: Unknown
• Capacity: The aircraft is a multi-level airliner and the passenger capacity is unknown, possibly 2,000-3,000 passengers and crew
• Maximum payload: Unknown
• Propellers: 8 propellers. There are 4 ducted propeller housings and each propeller housing holds 2 propellers.
• Electric Motors: 8 electric motors
• Power source: Long electric cord provides power to the eVTOL aircraft
• Fuselage: Carbon fiber composite
• Windows: Large windows providing better views for the passengers
• Skylights: Skylights on the top deck provide a luxurious ambience for both passengers and crew
• Landing gear: Retractable quadricycle wheeled landing gear
• Safety Features: Distributed Electric Propulsion (DEP), provides safety through redundancy for its passengers and/or cargo. DEP means having multiple propellers and motors on the aircraft so if one propeller fails, the other working motors and propellers can safely land the aircraft.
