H2S Dynali

Dynali H2S


Spacious and powerful helicopter with a high payload.

General description

Cellule Dynali H2S light helicopter

Light aviation type helicopter with a MTOW of 700kg.
Dynali H2S helicopters have two seats and dual controls.

Suitable for all uses : utilitarian, school, leisure.

This model is supplied as a kit or in flyaway condition according to the regulations in the destination country. Certain countries authorise helicopters in the light sport aircraft category.

In most countries, the Dynali H2S is authorised in the kit-experimental category.

When it is sold in kit form, the user is responsible for the assembly of his kit and may be assisted by a mechanic of his choice. Altough, many clients build them alone.

When it is sold ready-to-fly, Dynali Helicopter Company provides the customer a helicopter built following the latest aviation assembling rules, giving the customer the certitude that the machine has been tested properly.

In practically all countries, the pilot must hold, at least, a private pilot’s license.

Main characteristics

Structure H2S Dynali light helicopter

The Dynali H2S is designed from 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.

The wide section tubular aluminium undercarriage skids ensure stability on the ground.

The cabin fairings play no structural role.

The H2S has a tubular aluminium tail boom with decorative fairings.

The rear transmission is by drive shaft.

The rotor blades are made of high technology composite materials.

The cyclic plate is a high-performance device that allows for dynamic and easy piloting.
The Main Transmission Box is attached to the chassis, just above the engine.
The Dynali is designed for maximum passive safety for relatively little weight.
This passive safety is provided by the capacity of the structure to resist and provide
progressive deformation on impact.

Safety first!

 Rear rotor H2S Dynali light helicopter

All mechanical parts are over-dimensioned. The main rotor mast is rigidly attached
to the chassis to a point close to the rotor, to ensure the safety of those on board.

The composite rotor blades resist
over time without risk of wear or permanent deformation.
The tail rotor is solidly surrounded.
It can stand tail strikes on the ground
or impact on a wall.

The chassis and the landing skids are very strong and forgiving. Our ground tests allowed a 600ft/min impact with the MTOW.

The cabin fairings, strengthened with Kevlar are flexible. In the event of impact, the Kevlar is deformed without fracturing.
The Dynali is the ideal helicopter for training
purposes.

Use and piloting

Comfortable : the seats are well cushioned, the trimmed controls are light to handle.
There is no vibration at all in the cabin. The cabin is wide enough (1,4m) for two broad-shouldered
people to fly in comfort.

Flight controls are conventional, fully dual for training student pilots.
The cyclic sticks are adaptable to people of all sizes. The collective is also dual.

The engine is over-powered (180HP). A governor assists automatically with throttle control.
Piloting is precise and handling is easy. The controls respond immediately.

The rigid structure allows for highly dynamic piloting of the Dynali. It hugs the contours and instantly responds to the controls. No other light helicopter can be flown like a Dynali without the risk of deformation of the structure and inversion of the controls in tight turns. The Dynali H2S can fly in high winds thanks to excellent stability and a powerful tail rotor. It has excellent characteristics in autorotation.

The H2S has the advantage of having a two blade main rotor which allows for easy storage or transport on a trailer.

For long trips, the blades can be easily removed and do not require re-adjustment on re-mounting.

The H2S does not suffer from corrosion. Aluminium parts are anodized and composite parts are totally corrosion resistant.
