Monaco-based E Yo Copter says that “One Ton” should be able to lift 1,900 pounds of cargo! Intended to be used for military, parapublic, and agricultural applications, One Ton is powered by four German-made JetCat P550 turbine engines that spin the aircraft’s rotors by forcing exhaust out of two rotating pipes.
Each JetCat turbine produces 70hp (52kW). E Yo Copter says when the turbine is spinning at 80,000rpm the attached rotor spins at about 1,300rpm. The company claims the system produces no torque and saves weight by going without a turboshaft.
Each 3-blade set of rotors on the quadcopter are 2.75m in diameter. The entire aircraft is 6m across.
The UAV has an empty weight of 140kg (309lb). It derives its name from its 1,000kg maximum take-off weight. The aircraft carries enough fuel for a 1.5h flight.
The company is solely backed by its chief executive, Jean-Claude Tourn, who says he is looking to license E Yo Copter’s technology or form a joint venture with another firm to produce the UAV
