This machine successfully combines new engineering solutions and more experience in the development of coaxial-type helicopters. ultralight helicopter, rotorfly helicopter, double helicopter, Rotorfly - a new word in ultralight aircraft. In addition to the qualities that characterize the coaxial design of the rotor screws, such as aerodrome symmetry, independence of the control channels, no cost to the tail rotor, it will please you with excellent flying quality, worthy of the most demanding conqueror of the sky! Compactness, low noise level, reasonable price, convenience and simplicity in operation make Rotorfly helicopters the most accessible for private pilots, when performing air operations. This machine successfully combines new engineering solutions and more experience in the development of coaxial-type helicopters. The tests carried out prove the viability of the developed design, its high reliability and attractiveness.
HELICOPTER «ROTORFLY» can be used:
As an individual vehicle
For official transportation (rescuers, medical staff, shift workers, etc.) or commercial transportation (air taxi, express delivery of cargo and mail)
For training in piloting skills, incl. For training and participation in competitions
For air travel (sightseeing flights)
For prospecting, patrolling and monitoring
The use of skid chassis and the possibility of installing a ballonet on them makes it possible to land on any surface, including water bodies
Advantages of coaxial design:
Compact: Blades of coaxial screws and tail boom are shorter than on single-rotor helicopters of similar class.
Requires a minimum in comparison with other schemes, the runway
The absence of a critically vulnerable steering propeller and transmission inherent in single-rotor helicopters makes the Rotorfly P-30 safe (according to statistics, 10% of aviation incidents associated with the operation of helicopters are associated with the steering screw)
The efficiency of coaxial screws is more than for single-rotor helicopters, at least 20% (there is no loss of power to the steering screw)
Aerodynamic symmetry: A coaxial device can fly in any direction with practically the same efficiency
The "clean" shaft of the upper main rotor does not create swirls of the oncoming flow (the control rods are held inside the shaft)
To reduce the overall height, the shaft of the upper screw is lowered along the axis along the bearing supports.
The two-bladed screw reduces the dimensions of the helicopter in width, which is convenient for parking, transportation and storage.
