About Orca eVTOL Aeronave médica de emergencia

Orca eVTOL es una aeronave médica de emergencia con capacidad de despegue y aterrizaje vertical eléctrico. La aeronave, pilotada por una sola persona, transporta a tres ocupantes y está fabricada con materiales compuestos de fibra de carbono. Siete motores eléctricos independientes, alimentados por baterías de litio, proporcionan la propulsión y aumentan la seguridad. La envergadura es de 12,45 metros y la longitud de 8,1 metros. Los motores eléctricos arrancan en cuestión de segundos, mientras que los motores de turbina requieren un tiempo de calentamiento. El vuelo con alas permite una velocidad de crucero superior a la de las aeronaves de alas rotativas, por lo que los pacientes reciben tratamiento antes.

Unique Properties: The Orca eVTOL is a vertical take-off and landing aerial vehicle equipped with electric propulsion. The single piloted Orca has been designed to compeete with current emergency rotorcraft by transporing patients at higher speed, lower operational cost and incerased safety due the installed 7 independent electric engines and advanced aerodynamic design. The possible range of the carbon composite aircraft with three person on board and with current battery technology is up to 120 km.
Dimensions & Packaging: The wingspan of the Orca is 12.45m, its length is 8.1m with an overall heigth of 2.4m.
Tags: VTOL, electric propulsion, emergency medical services, aircraft, battery propulsion
Production Technology: The proposed concept uses high performance carbon fibre composite materials, common in aerospace industry. The integrated electric motors have already a proven background in motorsport and run entirely on lithium-based batteries.
Design Challenge: The most challenging part of a VTOL design is to combine design methodology of fixed wing aircraft and rotorcraft, two different regimes of aviation that are well documented when investigated separately but is still full of unknown obstacles when treated as a single regime. Having to run engines effectively while hover and during levelled cruise flight introduced energy management challenges.
Research: The design of the Orca eVTOL started with setting the flight performance requirements such as minimum range, payload, and cruise flight speed. All these emerged from a typical flight profile for a rotorcraft used in emergency medical operations. After deriving the strict performance requirements, a major effort was made to design an easy to operate yet safe aircraft architecture. This resulted in a so called three-surface aircraft with top positioned main wing and with axisymmetric fuselage.
Inspiration: The concept of the Orca electric vertical take-off and landing aircraft (eVTOL) was designed to challenge the current rotorcraft market used in the emergency medical services. With continuously advancing battery and electric engine technology, the concepts of eVTOLs became feasible. In the airborne medical services, introducing electric propulsion and winged aircraft concepts, the response time can be significantly reduced. All this to help avoid fatal outcomes of such situations.
Project Duration: The time required to design the Orca eVTOL from the first sketches to this stage covered six months. The design team has its headquarter in Pécs, Hungary.
Operation Flow: When alarming the rotorcraft medical services, the gas turbine engines of the rotorcraft have a warm-up time. This can mean up to 3 min before the take-off. With electric engines all this is reduced to seconds only. Due to the flight speed limits placed on the helicopter’s rotating blades, the wing borne flight of the Orca allows a higher maximum cruise speed. All these reduce the time form the emergency call until the treatment of the patients and the transfer flight back to the hospital.
