This ultralight helicopter has now opened the unique pleasure of helicopter flight to the general public.
The Dynali H3 EasyFlyer Sport is an ultralight helicopter authorised in Europe under the ultralight helicopter category (MTOW 450kg). Also, the Dynali H3 EasyFlyer has sufficient power reserve to lift around 600kg, this being of great interest in countries applying FAR certification.
The Dynali H3 EasyFlyer Sport has been designed to meet the latest standards in the aviation industry while keeping all elements of the design very simple.READ MORE
The H3 has a monoblock tubular stainless steel chassis ; this is the principal structure to which all components are connected.... The chassis frames the engine and the mechanical parts. It directly supports the seats and the cabin fairings. Where other light helicopters have a dangerous thickness of less than 1mm, the chassis of the H3 is designed for maximum passive safety with an average material thickness of 2,5mm in the tubular structure.READ MORE READ LESS
The rotor mast is made of Cr-Mo steel and designed to bear a load of +22G.
The main rotor consists of two blades articulated in pitch. The teetering hinge rotor allows for great flexibility in use and... allows for tighter turns than most similar machines. The rotor blades are either in extruded aluminium or (optionally) in carbon composite. Aluminium does provide very good resistance in poor weather conditions while carbon blade does only provide an extended lifetime.READ MORE READ LESS
The H3 EasyFlyer is powered by a 4 stroke Rotax flat four engine. From this engine, Dynali can offer three different engine configurations...READ MORE
The main transmission gearbox transfers the rotating movement from the main transmission shaft to the main rotor mast.... The MTG of the H3 is dimensioned to support 250 HP whereas in reality it only has to bear a maximum of 115 HP. The gearings are fabricated from aviation quality steel which is thermally treated and lubricated in a mineral oil bath.READ MORE READ LESS
The horizontal stabiliser provides excellent pitch stability. The vertical stabilisers are oriented 4° in relation to the longitudinal axis... of the helicopter. They compensate for the rotor torque by their aerodynamic effect. Thus the pilot does not need to use the rear rotor permanently. In the unlikely event of engine failure, the pilot can easily keep his heading by simply maintaining forward speed until flare.READ MORE READ LESS
The coolant radiator of the H3 is a very important item for training schools. It is very large and allows for the H3 to be flown in hover for long periods... without over-heating, without the requirement for periodic circuits to cool the engine oil.One (or two for hot climates) oil radiators are positioned on the coolant radiator and provide the same high efficiency performance. Two large fans, equipped with thermo switches allow for the automatic independent regulation of coolant and oil temperatures at ideal levels.READ MORE READ LESS
The clutch system of the H3 is commanded from the cockpit. It serves to connect or disconnect the engine to the transmission system.... When disconnected, it allows the engine to start with the rotor stationary, ensuring the safety of those on the ground during warm-up. Once ready for takeoff, the rotor is engaged by the pilot using a switch on the instrument panel.READ MORE READ LESS
Storage lockers are provided for personal effects and documents beneath the cabin seats.
