Founded in January 2021 in Munich, Germany, the Emotion Aircraft company is in the business of designing and manufacturing passenger electric vertical takeoff and landing (eVTOL) aircraft for advanced air mobility (AAM). The company founders started designing their aircraft as early as 2017 and the final production design was approved in November 2020. The company has built and successfully flown a ⅓ scale technology demonstrator aircraft.

Emotion passenger eVTOL and STOL concept design aircraft
The Emotion is a modern sleek two passenger eVTOL concept design aircraft. The aircraft can takeoff and land vertically and the aircraft can takeoff and land on a runway, like a conventional general aviation airplane. (STOL means short takeoff and landing.) The aircraft holds one pilot, one passenger and their luggage. The company has stated the aircraft has been designed for superior aerodynamics using computational fluid dynamics (CFD) simulation software to optimize the design to maximize every flight phase from vertical to forward flight. The design increases the performance of the aircraft, provides excellent efficiency, improves flight stability and has improved redundancy.

The cruise speed is expected to be 250 km/h (155 mph), with a maximum speed of 290 km/h (180 mph) and to have a never exceed speed of 322 km/h (200 mph). The estimated range of the aircraft is 600 km (373 m) with a flight time of just under two and a half hours. The aircraft has 16 tilt-propellers, has 16 electric motors and uses lithium-ion batteries for its power source. The aircraft has two falcon-wing doors and the cabin has larger than conventional aircraft windows providing excellent views for the occupants. The empty weight of the aircraft has been calculated to be 380 kg (838 lb), has an anticipated maximum payload weight of 220 kg (485 lb) and has a projected maximum takeoff weight of 600 kg (1,323 lb).

The aircraft has tandem wings with the front wingspan having a length of 5.5 meters (18.04 feet) and the rear wingspan having a length of 6.1 meters (20.01 feet). The aircraft is made from carbon fiber composite to give it a high strength to low weight ratio. The length the aircraft is 4.3 meters (14.1 feet) and the height is 1.84 meters (6.04 feet). The aircraft has two rear vertical stabilizers and one small ventral strake under the rear of the fuselage. The aircraft has tricycle landing gear with two forward fixed wheels and one retractable rear wheel. This is also known as a taildragger landing gear configuration.

The safety features of the aircraft include distributed electric propulsion (DEP) which means that if one or two propellers or electric motors fail, the remaining propellers and electric motors can land the aircraft safely. The aircraft can also land and take off like a conventional airplane. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy. Having multiple redundant systems on any aircraft decreases having any single point of failure.

The company has stated their aircraft will be inaudible to people on the ground when the eVTOL is flying over 300 meters (984 feet) in altitude.

• Tail: 2 vertical stabilizers, 1 small ventral strake (or also known as a downward vertical stabilizer)
• Landing gear: Tricycle land gear. (Two front fixed wheels and one rear retractable wheeled landing gear.)
• Safety features: Distributed electric propulsion (DEP) means having multiple propellers (or electric ducted fans) and multiple electric motors on an aircraft so if one or more propellers (or electric ducted fans) or some electric motors fail, the other working propellers (or electric ducted fans) and electric motors can safely land the aircraft. DEP provides safety through redundancy for passengers or cargo. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy. Having multiple redundant systems on any aircraft decreases having any single point of failure. The aircraft can also land and take off like a conventional airplane.
