India's Sarla Aviation Completes Sylla 1.0 Half-Scale eVTOL Flight Test Campaign
Indian aviation startup Sarla Aviation has announced the successful completion of its flight test campaign for Sylla 1.0, a half-scale eVTOL technology demonstrator. Over six months, the program logged more than 500 tests and over 18 hours of flight validation. The 700 kg aircraft with a 7.5-metre wingspan set the record for the heaviest electric aircraft to achieve vertical takeoff in India, while establishing several other domestic electric aviation firsts.
Highlights
- Sarla Aviation completed the Sylla 1.0 half-scale eVTOL flight test campaign after six months, 500+ tests, and 18+ hours of flight time.
- The 700 kg, 7.5-metre wingspan Sylla 1.0 set the record as the heaviest electric aircraft to achieve vertical takeoff in India.
- The programme validated a 400-volt electric powertrain and distributed propulsion wing system for the first time in India.
- Sarla Aviation has commenced development of Sylla 2.0, which will target controlled transition between vertical and wing-borne flight.
- Achieving transition flight in Sylla 2.0 is a prerequisite for Sarla Aviation to develop a certifiable passenger eVTOL air taxi.
Indian aviation startup Sarla Aviation has announced the formal completion of the flight test campaign for Sylla 1.0, its half-scale electric vertical takeoff and landing (eVTOL) technology demonstrator.
Setting Indian Electric Aviation Records
According to the company's press release, the Sylla 1.0 demonstrator completed more than 500 tests and accumulated over 18 hours of flight validation during a six-month ground and flight test programme. At 700 kg and with a wingspan of 7.5 metres, the aircraft became the heaviest electric aircraft ever to achieve vertical takeoff in India.
"Sylla 1.0 is a half-scale technology demonstrator designed to validate airframe systems and system integration in real operating conditions," the company stated. "Throughout the programme, Sarla successfully evaluated the interactions between the aircraft's electric propulsion system, battery architecture, distributed propulsion, flight control algorithms, airframe structure, and landing gear — assessing them as a fully integrated aircraft."
Multiple Indian Electric Aviation Firsts
The Sylla programme established a series of domestic firsts in Indian electric aviation:
- First 700 kg-class electric aircraft capable of vertical takeoff to be built and flown in India
- First 400-volt electric powertrain architecture to be flown in India
- First distributed propulsion wing system to be validated in India
- First full ground test suite completed in India in accordance with airworthiness regulations
Development of Sylla 2.0 Already Underway
Sarla Aviation confirmed that development of an upgraded demonstrator — Sylla 2.0 — incorporating engineering lessons from the current programme has already begun.
"While Sylla 1.0 focused on validating integrated aircraft systems and controlled hover flight, Sylla 2.0 will pursue controlled transition between vertical flight and wing-borne flight — a critical technical milestone that must be achieved before developing a passenger eVTOL capable of obtaining airworthiness certification," the company explained.
Achieving transition flight capability would bring Sarla Aviation significantly closer to its vision of commercial passenger air taxi services, and signals that India's homegrown eVTOL sector is steadily closing the gap with global development efforts.
