Sabrewing Aircraft plans to perform the first flight of its Rhaegal unmanned heavy-lift, long-range half-scale prototype aircraft by the end of March, says Ed De Reyes, Sabrewing chairman and CEO, according to a recent publication by Janes.
This half-scale prototype has an 8.5 m wingspan, and will be roughly half the weight of the full-size production aircraft. The full-scale Rhaegal that will go into production will have a wingspan of 17 m, said De Reyes, adding that the company started with the half-scale prototype to make it easier to operate, and for it to perform avionics and autopilot development.
The full-scale Rhaegal will feature a turbo-electric powertrain that will be fuel-efficient and not require a charging station. Sabrewing is installing a Safran Arriel 2D turboshaft engine that it received for free from Safran into the half-scale prototype for use in its upcoming flight test. The Arriel 2D, which powers the Airbus H125 and H130 single engine commercial helicopters, features a take-off power of 952 shaft horsepower (shp), and a cruise power of 856 shp.
