Umiles Group was founded in San Sebastián, Spain in 2016 and became a leading company in unmanned aerial systems. The company offers custom services for national and international customers. In 2019, the company's first flight of an electric vertical takeoff and landing (eVTOL) passenger prototype aircraft took place in an indoor stadium. In 2020, Umiles Next was formed. The company's goal is to be a world leader in advanced, efficient and sustainable mobility for both eVTOL passenger aircraft for advanced aerial mobility (AAM) and ground transportation to improve people's lives. The company's goals are to provide an aircraft that is made with passenger comfort and the use of sustainable materials.
In 2022, Integrity 3 entered the design phase. The aircraft is a two passenger, one pilot eVTOL medium range aircraft. The aircraft has a maximum speed of 220 km/h (137 mph) and has a flight range of 125 km (78 miles). The empty weight of the aircraft is 1,000 kg (2,204 lb), has a maximum payload of 300 kg (662 lb) and has a maximum takeoff weight of 1,300 kg (2,866 lb).
The aircraft has one high main wing and in the middle of each wing is a tilting propeller assembly. Each propeller assembly has four booms attached at 90 degree angles to each other and at each end of each boom, is a propeller. Electric motors are located directly under each propeller. The aircraft has a total of eight propellers and eight electric motors on the tilting propeller assemblies. There is also one stationary VTOL propeller located inside the rear horizontal stabilizer (or a propeller-in-wing configuration). The aircraft has a grand total of nine propellers and nine electric motors.
For forward flight, the tilting propeller assembly sits inside a depressed semicircular shaped part of the wing. Then for VTOL flight, the propeller assembly lifts vertical flight. Each propeller assembly can tilt independently of each other and each propeller can work independently of all other propellers providing the aircraft with excellent stability and controlability in calm to gusty winds in real time.
The windows are larger than conventional aircraft and provide a panoramic view allowing forward, left, right visibility, for spectacular views for the passengers, with a solid roof above the passenger compartment. The rear tail is horizontal stabilizer which is at the same height of the main high wing. Over the horizontal stabilizer is another inverted u-shaped horizontal stabilizer connected to the ends of the lower horizontal stabilizer with two vertical stabilizers. The aircraft has fixed tricycle wheeled landing gear, with a single wheel in the front of the aircraft and has two rear bogies, each bogie having a set of two wheels.
The company expects Integrity 3 to be used for executive air service, tourism, on-demand air taxi service, personal use, police, fire, disaster relief, emergency use for doctors, search and rescue, government use and air cargo service.
Windows: Panoramic wrap around windows allowing forward, left, right visibility, for spectacular views with a solid roof above the passenger compartment
Wings: 1 high main wing with winglets
Tail: Horizontal stabilizer with an inverted U shaped horizontal stabilizer connected to the ends of the horizontal stabilizer with two vertical stabilizers
Landing gear: Fixed tricycle wheeled landing gear, with a single front wheel and has two rear bogies, each bogie having two wheels
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.
