The Dynali

912 ULS-I-BB

Technical sheet

 

Based on a Rotax engine, the Dynali 912 ULS-I-BB provides 135 hp with the most appropriate power configuration for a helicopter thanks to the ECU controlled electronic injection system coupled with bigger bore cylinders. 

It provides a perfectly linear torque and comfortable power reserve, without increasing weight. In addition, the fuel consumption remains around 22 L/h (5.8 gph). It has the best power to weight and power to fuel consumption ratio.

Assembly Line

Dynali helicopters are manufactured and fully assembled from A to Z in a single production site in Belgium. All mechanical parts are machined and welded in our factory. The Dynali 912 ULS-I-BB is based on a Rotax engine block to which Dynali has added its own injection system and an ECU entirely mapped by our engine specialists. Cylinders, pistons and other critical parts have been designed by Dynali to provide 135 hp and an engine fully adapted to helicopters.

Following assembly, the engine spends 5 hours on a test bed for break-in. All parameters are monitored during a normalized procedure. After this step, the assembly is finalized and the bodywork can be performed. This stage includes painting of the fairings in our paint shop equipped with a paint mixer and a chromograph. This allows the client to specify exactly the colour scheme desired. Finally, the helicopter is submitted to 5 hours of test flights covering the full flight envelope – then a quick wash and polish and it is ready for delivery to the lucky customer.

It is this integration of the production processes which enables Dynali to quote very short delivery times (around 120 working days).

A Highly Qualified Team

The company currently has 25 full time employees, working in a 4 000 square meter factory in Belgium. A large part of the personnel is employed on the production line, while a team of engineers works full time on development of the UAV / drones designed to provide tailor-made solutions to customers’ specific problems.

The concentration in a single production site of all the skill sets required for the manufacturing and assembly of helicopters, from engine preparation to avionics, provides Dynali with tight control over all processes and offers a guarantee of quality and short delivery schedules.

Our Process of Production

We have several CNC machines that manufacture 90% of the H3 components. All the components are then stored in-house.

All the airframe parts are welded in our factory in Belgium.

Our paint cabin has a computer-controlled paint mixing system and chromatograph.

At Dynali, we receive the engines from Rotax. We start by completely disassembling them. We set asides various parts in order to work mainly on the casings so they fit with our components manufactured in-house such as the cylinders. The crankshaft is balanced. We also work on the intake and injection systems. We install an electronic throttle body which is controlled by a MoTeC ECU. It helps us managing a power that reaches 135 HP.

After the engine preparation, we install the engine on the helicopter and we install the helicopter airframe on the Dyno Bench to collect every data from the engine. We do an engine break-in during 5 hours. During this tests we collect all the parameters from the engine like pressions, temperatures, vibrations. We do these tests with a normalized procedure.

Finally we bring the helicopter back on the assembly line before the flight tests. Our test pilots are exceptionally experienced and perform a 5-hour flight test in numerous scenarios.

Maintenance & Operating Costs

The maintenance program for the H3 Sport is one of this machine’s greatest advantages. The entire helicopter has been designed for ease of access, simplicity and low cost of maintenance for the owner. It can be performed easily thanks to detailed but very simple technical procedures.

The general TBO of the H3 Sport is at 2000 h and has no calendar limited service life. Service inspections are spaced at every 50, 100, 250, 500, 1000 and 2000 h.

FAQ

Find the answers to all your questions about the helicopter. we also answer your questions about the drone.

Yes. The kind of license will depend upon the applicable regulation in your country. In many countries, the Dynali H3 Sport is considered and certified as an “ultralight” helicopter and thus requires an ultralight helicopter pilot’s license. The process for obtaining such a license is relatively simple as compared with a “PPL/H” or private helicopter pilot’s license. In the countries where the helicopter is certified and registered as a kit-experimental helicopter, you will usually have to pass a PPL/H license.

Dynali sold nearly 1 000 fixed wing ultralight aircraft before starting to develop helicopters. To-date over 200 Dynali helicopters have already been delivered on 6 continents, including 120 H3 Sport.

The purchase prices of the H3 Sport can be found on the “Price” page of the site, together with the price of all the options. The H3 sport is the lowest cost side by side two-seater helicopter in the world thanks to a very huge investment in a serial production line. All prices quoted by Dynali are ex-works and tax excluded.

Yes. At least as regards the theoretical part of the course. Weather, communications, etc. are the same whether in fixed wing or rotary aircraft. Having some experience on fixed wing aircraft or gyroplane will surely help, but flying a helicopter requires some more training as it is very different.

No. Dynali does not have a flight school. However Dynali can arrange “conversion” training for pilots with helicopter licenses and recommend schools where flight training is provided using Dynali H3.

One Dynali helicopter can be shipped in a 20’ container, with just the removal of the main rotor blades and two blades from the tail rotor. Reassembly takes less than one hour.

Yes, everything is included to allow for legal and safe flight in VFR daylight conditions. Additional instrumentation, transponder, radio are among many options available. When the helicopter is delivered, all the assembly has been carefully inspected according to the complete control protocol. Five hours of flight tests and commissioning are performed before delivery.

Yes, with an H3 Sport, your instructor can certainly train you on your own machine.

Yes. The H3 can be serviced by their owners or, under the owner’s responsibility, by a technician at the local aeroclub. A maintenance training in Dynali facility is though strongly advised and in some situation, required by Dynali.

98 octane automobile fuel.

It depends on the local regulation in your country, regarding light helicopter. In Europe, the H3 Sport falls into the ultralight helicopter category which allows for that.

Yes. Every Dynali helicopter undergoes ground tests and at least 5 hours testing through the full flight envelope by the company pilot before shipment.

Yes. Every Dynali helicopter is fitted with a governor to maintain the constant rotor speed required for helicopter flight. The governor is fully automatic and does not require any action from the pilot during the flight.

This depends on the status of the order book at the time of placing of the order. The maximum delivery time is 6 months. However, it is only when the firm order and the 50% deposit have been received that a chassis number is allocated and a firm delivery date, which may be considerably shorter, can be confirmed. Usually, the delivery time rounds 3-4 months.

Dynali welcomes potential distributors and customers at its facility in Belgium. Access is fairly easy as Dynali is at mid-distance between the Brussels National Airport and Charleroi airport (Ryanair hub), and Dynali can provide airport pickups. Alternatively the company is 10 minutes from Nivelles station which is itself a 20 minute train ride from Brussels Midi station, from where Eurostar, Thalys and TGV high speed trains link Brussels to the rest of Europe. An aeroclub 5 km from Dynali welcomes visiting ultralight aircraft (Baisy-Thy/EBBY).

Excellently, there is considerable inertia in the main rotor due our choice for very heavy rotor blades and all those who have tried it have been impressed by its docility in autorotation.

For a competent aircraft mechanic it is extremely simple. For those among us who have no mechanical experience, it is probably safer, at least at first, to leave it to a professional who has a copy of the maintenance manual.

First just send an email to info@dynali.com and tell us a little about you and your operation. We will then contact you and send you a standard Dynali distributor contract and invite you to visit the factory, see the manufacturing processes and talk with all our key people. The main requirements for a distributor are to buy a demonstration machine, having a flight school, at least one pilot and one qualified technician trained on H3. If everything fits, for you and for us, we sign a distribution contract.
