Leonardo Studies Second-Generation Rotary-Wing UAV

Leonardo’s new SW-4 Solo would be an optionally manned derivative of this SW-4 light turbine helicopter,

Leonardo is studying concepts for a second-generation rotary-wing unmanned air vehicle for use in both land and maritime environments. The European manufacturer is building on its experience with its AWHero 150-kg (330-lb.) light rotary-wing UAV and the SW-4 Solo, an optionally manned derivative of the SW-4 light turbine helicopter built in Poland.

Revolutionary Coaxial Drone with Diesel Piston Engine – Optionally Piloted Helicopter


Turbines have an excellent power to weight ratio and as such are the reason is why they are used for helicopters where weight is a critical factor. Nevertheless, their fuel efficiency compared to diesel piston engines is extremely poor, especially for smaller platforms. The diesel piston engine consumes +/- 60% less fuel compared to a turbine with similar specifications and produces up to 40% less CO2 than standard turbine helicopters. Continue reading
