SH18LC
The winged flagship. Sixteen lift rotors, two cruise propellers and a 48-foot wing — the world's first aircraft to fly on Distributed Digital Displacement Hydraulic Propulsion, with up to 540 km of range.
Built for the long sectors — Colombo to Jaffna, Trincomalee or Batticaloa — where a wing beats a battery every time.
Straight up. No runway.
Sixteen hydraulically driven rotors lift the aircraft from a vertiport, a beach or a floating platform.
Steady as a rock.
Digital displacement motors adjust every rotor independently for precise, stable hover.
Wing takes the load.
The cruise propellers accelerate the aircraft until the wing carries it.
Lift rotors rest.
With the lift rotors stopped, the SH18LC cruises efficiently on two variable-pitch propellers.

- Real luggage space — six large check-in cases and two cabin bags.
- On-board toilet for comfortable long sectors.
- Glass cockpit with intuitive digital displays.
Two engines. Two layers of safety.
Each engine powers its own hydraulic circuit. Lose one, and the aircraft still has options.
Land vertically
With one engine failed, the SH18LC can still complete a controlled VTOL landing.
Keep flying
It can continue flying on a single engine to reach a safe landing site.
From cruise back to hover.
On approach the lift rotors spin back up and the aircraft slows into a hover over its landing zone — a vertiport, a resort lawn or a quiet stretch of water.
Every angle.
