Why do we say that the ARGON Gyro is the safest ultralight aircraft?

 

Firstly, we believe that the new-generation, professionally designed and constructed, gyrocopters are inherently safer than fixed wing and helicopter aircraft of similar size.  Why?  Because a gyrocopter can descend vertically under full control and land in just a few metres of space, without the complexity or cost of a helicopter.  So a new-generation gyro always provides more options in case of emergency than a fixed-wing and is less likely to experience a technical failure than a helicopter.

 

So why is the ARGON the safest gyrocopter?

 

 Most gyrocopters are built around a metal chassis, to which everything else is mounted, like cars were until recent years.  The ARGON is different.  Using the latest carbon fibre technologies, the cabin of the ARGON is an engineering work of art.  It is constructed around a light but immensely strong monocoque protective shell, like a formula one car.  This shell provides both a crush-proof protective enclosure for the crew and allows all the other components to be directly mounted to it, without the weight of a chassis or additional structural frame.

This provides a massive degree of safety for the crew in the event of any kind of accident, because the cabin is capable of withstanding loads that are many times the acceleration of gravity.

Monocoque fuselage construction means that forces are transmitted through the fuselage instead of via the rods and tubes of a frame.  ARGON is one of the few gyrocopters in the world that uses monocoque construction, and it is now available in carbon-fibre, which offers unparalleled strength and low weight for safety and performance.

In the design process, sketches and drawings are transferred to Computer Aided Design (CAD) software, which then allows precise rendering from any angle and computational performance testing to check the ergonomics of the machine, and make rapid and cost-effective refinements, before even manufacturing a prototype.

 

Our cabin is also equipped with controlled crumple zones, just like a modern car. The most important is the nose of the cabin, which in the event of a collision, progressively absorbs the energy to protect the crew.  Another important crumple zone is the bulkhead wall separating the cockpit from the engine compartment. It is a structure that is carefully reinforced with composite profiles. The ARGON cabin has also been designed with large pilots in mind, allowing even tall and wide individuals to feel comfortable. As a result, the ARGON offers better safety, cabin volume and comfort than any other gyrocopter in its class.

 

Ergonomics and ease of use, combined with ultra-modern technical solutions, lie at the core of ARGON.  But at the same time, at Manufaktura, we have a very great respect for nature.  Over millions of years, dating back to the dinosaurs and before, nature has evolved very effective ways to deliver strength and agility at the least weight and cost.  The ARGON borrows from nature through biologically-inspired features such as the reinforcing ‘ribs’ in the cabin and the use of ‘honeycomb’ materials.

Take for example the seat.  Made from carbon composite and foam-filled Kevlar, This design is able to save our spine in an accident. The seats can also "crumple".  Similarly, just as a blade of grass or a young, flexible sapling might survive a severe storm, whereas an old and strong tree might fracture and fall, nature has lessons for us about providing flexibility in structures that yield, rather than snap, under load.

 

But the real test is the moment where theory meets practice, starting with the strength tests that are part of our rigorous certification procedure.  Together with the Institute of Aviation at the Technical University of Warsaw, we conducted a comprehensive study of the strength of the cabin and associated components. This not only confirmed the expected strength, but to everyone's surprise and delight, exceeded predictions.

In conclusion, the Argon cabin is the result of exploring leading edge technologies through hundreds of hours invested in analysis, testing and verification of the concept in practice, over 15 years of research and development. Looking at the finished design you can perhaps now appreciate that virtually nothing was left to chance; every item is the result of many hours invested in the project to achieve the maximum safety, comfort and performance at the most efficient cost.

 

The mast is a critical part of the structure. During the design process, engineers have to reconcile seemingly contradictory requirements, providing strength without sacrificing flexibility, firmly supporting the cabin with the lift from the rotors, while allowing the rotor blades to spin freely and to be angled in pitch and roll.

The mast must be very sturdy, because from it hangs the entire structure of the Gyrocopter, and yet at the same time there must be a safety zone to avoid serious injury in case of an unexpected collision of the rotor with an obstacle.

 

Using key design criteria and structural stress tests we developed a profile that is able to reconcile these seemingly contradictory tasks.  Our design is able to withstand overload mast stresses of several times the force of gravity, while failing ‘gracefully’ with controlled and designed crumple zones in the event of even greater stresses.  In the event of a severe accident, the mast breaks away, separating the spinning rotor from the cabin, avoiding injury to the crew.

The undercarriage is of simple design, directly connecting the wheels and cabin, seemingly nothing special.  But in all great design, the most elegant solutions often appear simple!  In fact, it is the fruit of many calculations, strength tests and prioritizing objectives to achieve the best active and passive performance, providing a smooth absorption of bumps over rough terrain, while offering great strength under many times the force of gravity in case of a heavy landing.

 

The Argon undercarriage is very wide, over 2.2m, a spacing unparalleled in other Gyrocopters.  This is very important, because it provides a high degree of stability during taxiing, take-off and landing, much better than in narrower Gyrocopters.  Also, the shape of the landing struts is slightly angled, to absorb energy in the event of a hard touchdown to reduce the transmitted stress to the cabin and crew.

View the comparison

1. Much More Cabin Space

 

The ARGON 915 Classic, our standard model, has a cabin that is larger than the competition - Cavalon and Niki.

And our ARGON GTL model has 25 more cubic feet than the ARGON Classic!

When you want to go places and do things, you need room for luggage, or camping gear, or cargo, or scanning equipment, or photo equipment.

Our ARGON models are designed to be more functional, more useful, and more capable than the two-place gyrocopter competition that squeezes

two-three passengers into a cabin, and not much more.

2. More Shoulder Room

 

A wider cabin, with more room between the seats is a major comfort advantage of our gyrocopters.

There is also a nice padded armrest between the seats. A hidden advantage of this extra room between the seats is

that the center instrument tunnel is so much wider. That makes it so much easier to access all of the control cables and sensor wires.

We have spent hours trying to make a fix in the small tube tunnel of a Cavalon, that only takes a minute or two in the wide tunnel of our ARGON gyrocopter.

3. Wider Wheelbase

 

With a long rotor spinning overhead, there is a tall force to deal with when taxiing for take-off and landing.

The much wider wheel base of our aircraft give you much greater stability especially when taking off and landing on grass or rough fields.

You can taxi on uneven ground, and make turns without being so careful of your ground speed.

4. More Ground Clearance

 

Grass landings, uneven and rough fields are no problem for our ARGON gyrocopters.

We have more than double the clearance of the competition, because of our taller landing gear,

and also because of our dual tail booms which keep well clear of the ground. Note that the competition,

which uses a single tail boom that curves down under their propeller has almost no ground clearance.

That tail boom goes much lower to the ground than the cabin, and will simply drag if a field is not pretty even and smooth.

5. Dual Tail Booms

 

When the whole horizontal stabilizer and tail rudders are mounted on a single bent pipe, like our competition does, there is definitely give and        vibration. We mounted a camera on a single tail boom Cavalon and recorded the shaking. Two straight tail booms are much stronger, and nearly vibration free.  Our aircraft have rock-solid stabilizers and even have dual rudders for more authoritative control, enabled by the use of dual tail booms.

6. Wider Horizontal Stabilizer

 

The weakness of early gyrocopters was a problem of "power push over"; engine thrust tipping the aircraft over and unloading the rotor,

or leading to pilot induced oscillation (porpoising) as the pilot pulled the rotor back to compensate.

Raising the cabin up, relative to the engine, which some gyro makers have done,

so that it receives center-line thrust is a solution that makes for a tall gangly aircraft.

So, the better answer is to add a much larger horizontal stabilizer to solve the push-over issue.

Our aircraft have a much wider stabilizer, for maximum stability.

Note that the height of this stabilizer is directly aligned with the centerline of the propeller's thrust, to maximize its effectiveness. It is the best solution on the market.

 

7. Much Greater Visibility

 

The joy and the utility of a gyrocopter manifests itself in being able to see your surroundings.

Our gyrocopters maximize visibility with a much larger front windshield which wraps down at the sides, and with windows in the front floor, windows in the roof, extended visibility downward in the doors, and even windows behind the doors. The ability see the runway directly below, through the floor windows, has helped many new pilots judge their landings much better, and master the art more quickly.

 

8. Engine Compartment

 

This is a trade-off advantage that we have come to greatly appreciate. Our partially open back does not look as streamlined as the fully enclosed Cavalon. But the open area eliminates the heat build-up issues that we had with the Cavalon. And their marvel of German engineering, that tucks the engine, turbo, radiators and oil coolers, etc. into the tiny cone of a compartment, turns out to be a nightmare when we are trying to reach components to inspect or service them. With our design, we can see at a glance, the fuel filters and fuel flow. It is amazing how much easier it is to adjust and service the engine because there is so much extra space.
