How in-flight testing technology is helping the next generation of sustainable eVTOL aircraft take flight
A
s the aerospace sector seeks to accommodate the increased importance placed on sustainability
by governments, world leaders and climate activists around the world, companies in the sector are developing more environmentally- friendly ways to design and test aircraft and their components. One company operating at the
forefront of the Electric Vertical Take Off and Landing (eVTOL) sector is German electric jet aircraft developer

Lilium, which is hoping to make the ‘green dream’ of electric flight a reality with its Lilium Jet. The proprietary technology at
the core of the Lilium Jet is Ducted Electric Vectored Thrust (DEVT), which has been refined through successive generations of aircraft demonstrators since Lilium’s founding in 2015. Proposed as an alternative to traditional jet engines which power around 95% of current commercial aircraft, Lilium’s electric jet engines rely on a single stage rotor system
driven by an electric motor to create propulsion. The jet engines are integrated into the aircraft’s wing flaps to increase payload and aerodynamic efficiency while reducing its noise profile. The engines also provide thrust vector control in order to manoeuvre the aircraft through each phase of flight. Gas flow measurement and control
solutions developer Chell Instruments is supporting the engineering and development of the Lilium Jet with its nanoDAQ-LTS air pressure
