SAMAD aerospace hits e‑Starling milestone with first flight of 50 per cent scale demonstrator
SAMAD aerospace has conducted the first flight test of a half-scaled prototype of its e‑Starling business aircraft, representing a key milestone as the company looks to commercialise the world’s first eVTOL hybrid model.
The CTOL flight test, which took place last month, saw the aircraft take off at a length of 250 meters to showcase the e‑Starling’s potential for short take-off and landing (STOL). Take-off and landing were smooth, and the vehicle maintained a comfortable cruise at a speed of 90 mph for more than five minutes.
Tests also included evaluations on aircraft flight dynamics, performance and handling qualities. As the e‑Starling adopts a semi blended wing body (BWB) design, it requires a low angle for take-off so it is important to understand when the aircraft is capable of taking-off and at which speed.
Commenting on the flight tests, Norman Wijker, SAMAD aerospace’s Chief Technical Officer, said: “CTOL trials are an essential step towards VTOL aircraft development. Ticking off the CTOL flight capability is a crucial step towards the validation of all flight modes.
“With CTOL trials complete, we will begin hovering trials and the flight trials will be concluded by transition between hovering flight and aerodynamic flight in both directions”
Apart from slow and fast taxiing on the runway as well as take-off and landing; the half scale demonstrator also performed banking manoeuvres in addition to tests on yaw, pitch and roll. The results show very stable in terms of handling quality.
Among other tests of subsystems were brake, telemetry, redundancy links, and ensuring the centre of gravity (CG) of the aircraft is at the correct design place. The aircraft’s performance matched the predicted calculations made during preliminary and detailed design stages.
When asked why a CTOL test is needed for a VTOL aircraft, SAMAD Aerospace’s Aircraft Design Adviser, Professor John Fielding said the ability to take off and land conventionally is an important part of the safety justification for VTOL aircraft.
“Safety is key. We have investigated various safety challenges via CFD analysis and now through the flight tests using this 50 per cent scaled CTOL prototype,” he said.
SAMAD aerospace has also said preparations are also under way to conduct a flight of a half-scaled eVTOL version of the e‑Starling. The model will be completed next year.
Based on the Cranfield Technology Park in Bedfordshire, UK, the company has been developing its manned and unmanned aircraft with two scaled prototypes — 10 per cent and 20 per cent — successfully built, flown, and showcased in reputable international air shows such as Farnborough, Geneva and Singapore.
