Crisalion Mobility Concept Integrity 1 (prototype)

Umiles Next Concept Integrity one passenger eVTOL multicopter prototype aircraft


Concept Integrity 1 (prototype)
Crisalion Mobility
Madrid, Spain

Crisalion Mobility 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. The company was originally named Umiles Group. In 2020, the company changed its name to Umiles Next. The company's first flying prototype was made by Tecnalia's Research and Technological Development Center (based in Spain).  On October 25, 2023, the company announced they changed their name change to Crisalion Mobility to better reflect the identity of the company.

Crisalion Mobility has received more than €15 million (EUR) from Grupo Ibérica and Grupo Valdemira (both based in Spain) that is being used to continue to expand its technology development and begin air service for advanced air mobility (AAM). In addition, Crisalion has commissioned the investment bank Blue Bull to seek investors for a funding round in hopes to raise between €20 to €25 million (EUR) additional euros. BlueBull, an investment bank specializing in high-growth technology companies, acts as exclusive financial advisor to Crisalion Mobility.

The company's purpose is developing and manufacturing electric vertical takeoff and landing (eVTOL) passenger and air cargo aircraft for advanced air mobility (AAM). In addition, the company is also developing remote controlled electric passenger ground vehicles. The company's mission is to be a world leader in advanced, efficient and sustainably manufactured air and ground mobility to improve people's lives. The company has its own technology that maximumizes aircraft stability and safety called FlyFree. Tecnalia developed the technology and many successful test flights with this avionics package have been made in Europe. The technology for safe remote driving of their ground vehicles is called IntellyDrive.

Concerning the new company name Crisalion Mobility, it is a blend of two concepts, the chrysalis and the lion. The chrysalis part of the  new name represents the transition from ground to air and is also a metaphor for the beginning of the new nacent aviation industry taking place right now around the world of advanced air mobility (AAM). The lion in the name represents the courage, strength and leadership it takes to build a company for urban and intercity advanced air mobility (AAM) and advanced ground mobility (AGM) for the future.

In 2019, the company's first flight of an electric vertical takeoff and landing (eVTOL) passenger prototype aircraft took place in an indoor stadium. The company has stated they are one of the first company's in the world to perform successfully flight tests of their eVTOL full scale prototype. Since 2022, the prototype has been making many outdoor test flights. The company also has a remote control center in Spain for their remotely operated ground vehicles.

Concept Integrity 1 passenger eVTOL multicopter prototype aircraft
The Concept Integrity 1 is a one passenger eVTOL multicopter prototype aircraft. The aircraft can be fitted with or without a seat and a canopy with or without glass. The prototype's first flight took place in Toulouse in September of 2022. In the same year, the second test flight was conducted at the ATLAS (Air Traffic Laboratory for Advanced Unmanned Systems) is a Test Flight Center located in Villacarrillo, Jaen, Spain.

The prototype has a cruise speed of 80 km/h (50 mph), a range of 15 km (9 miles) and a flight time of 15 minutes. The empty weight of the aircraft is 550 kg (1,212 lb), its maximum payload weight is 100 kg (220 lb) and its maximum takeoff weight 650 kg (1,433 lb).

The aircraft has a tandem-like boom configuration that make a total of four booms. Two booms are located at the forward bottom of the fuselage and the rear two booms are located near the top of the fuselage. At the end of each boom is a tilting propeller assembly where four booms are 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 16 propellers and 16 electric motors. Each propeller assembly can rotate independently of each other or they can move together at the same time.

The FlyFree avionics package maintains the passenger cabin in the same orientation as when landed throughout the entire flight. This means the cabin will not tilt in any other direction on takeoff, landing or when flying in any direction. The cabin will continuously be perpendicular to the ground. The production aircraft is planned to have precise landing and takeoff capabilities. The aircraft has fixed skid landing gear and can land on almost any surface in real time.

Future goals
The company expects Concept Integrity 1 to be used for on-demand air taxi service, personal use, tourism, police, fire, disaster relief, emergency use for doctors, search and rescue, government use and air cargo service. The company plans to make new road mobility (remote controlled ground vehicles) a real alternative by 2024 and advanced air mobility (AAM) by 2030.

  • Aircraft type: eVTOL passenger and cargo aircraft
  • Piloting: 1 pilot (in the future, autonomous)
  • Cruise speed: 80 km/h (50 mph)
  • Range: 15 km (9 miles)
  • Flight time: 15 minutes
  • Empty weight: 550 kg (1,212 lb)
  • Maximum payload: 100 kg (220 lb)
  • Maximum takeoff weight: 650 kg (1,433 lb)
  • Propellers: 16 propellers (in sets of 4)
  • Electric motors: 16 electric motors
  • Power source: Batteries
  • Fuselage: Carbon fiber composite
  • Window: Canopy over cockpit
  • Landing gear: Fixed skid 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.
