What is an autogyro? a look into the future...

Gyros, this word is familiar to all fans of aviation and for people not associated with the technique, the word is likely to be associated with something archaic, obsolete.

The first work on autogyros was carried out by Spanish inventor Juan de la Sierva. His work on these rotary-wing machines, in 1919, aroused great interest. In the Soviet Union, in the 30-ies, autogyros of well-known designers were actively developed. For example, in 1929, the KaSkr-1 “Red Engineer” was created by the designers Kamov and Skrzhinsky, which showed quite decent flight data. N.I.Kamov became better known as the creator of the Soviet Ka-brand helicopters.

Subsequently, with the development of aircraft, and most importantly helicopter technology, interest in autogyros fell, and all the work was practically curtailed. Autogyros or gyrocopters got their second birth in the USA, in 60 of the last century. American engineer and inventor with Russian roots, Igor Benson, began to vigorously promote flights on gyrocopters. The devices they invented were cheap, and available to the widest masses of the population. Managing them was very simple, and taking off from a small patch and landing with little or no run made this mode of transport interesting to the average man. His light autogyros were sold in the form of a designer from parts sent by mail, from which any practically person could assemble his own apparatus. In the wake of popularity in America and Canada, double-light autogyros were created, which received an official type certificate. Until now, some of them can be seen flying.


So what is autogyro or gyrocopter? Technically, the gyroplane occupies an intermediate position between the aircraft and the helicopter, or rather a hybrid of one and the second. “The autogyro combines all the flaws of an airplane and a helicopter,” but this, of course, is an old aviation joke. The fact is that of all the flying equipment, the autogyro is the safest species. The device is, in fact, the cockpit, single or double, with an engine that drives a pulling or pushing propeller for horizontal movement. And the function of the aircraft wing, to create lift, is performed by freely rotating rotor blades. The rotation of the blades occurs under the action of the incident flow. Rotating in the autorotation mode (free rotation), and installed with a positive angle from 0-6 degrees, the rotor blades create sufficient thrust to maintain the device in the air and all the necessary evolutions. The autogyro is not subject to a corkscrew, this terrible "beast", which aviators fear on airplanes. The fact is that, with a decrease in the translational speed, the gyroplane simply begins to smoothly decrease. Even in the event of a failure of the main engine, the gyrocopter is able to make a safe landing, being content with a small patch of surface.

Modern gyrocopters are popular due to their good flight characteristics, low cost, simplicity of design and control in the air, safety, the ability to fly with significant wind, when other light aircraft simply can not safely rise into the air. Thanks to the take-off from the jump, or just a significantly shortened take-off, and landing with low mileage or even by helicopter, the gyroplane becomes interesting for various services. Such as the service of forest protection, traffic police, fire inspection, monitoring services, transmission lines and pipelines. Yes, and lovers of flights for the soul, this device brings a lot of pleasure with a minimum of costs. Most modern autogyros are equipped with a drive for a carrying rotor, which spins up to take-off and allows for a minimum run-up reduction. In the air, the rotor is disconnected from the transmission and goes into autorotation mode.

Along with the undoubted advantages, the autogyro has several disadvantages. The main one is the low efficiency of the power plant. For its class among helicopters and airplanes by weight, it needs a more powerful engine, and, accordingly, higher fuel consumption. Like any other aircraft, the gyroplane has several dangerous flight modes that are unique to this species. But, it is enough to follow the instructions for flight operations to avoid such regimes.

Several well-known Western firms produce gyroplanes on an industrial basis. They have a comfortable cabin, usually closed, equipped with the necessary instrumentation for safe flight. They are sold ready-made, or delivered in the form of so-called KIT sets, for self-assembly. In Russia, several types of gyroplanes are also produced. Such as "Huntsman", "Raven-01M", Angara department of FLA of Russia, Autogyro "Kazachok", produced by the wife of Korneyev from Sergiev Posad (there is even a queue for this gyro!). "Laboratory of Aviation" from Yoshkar-Ola produces a gyroplane for travel M22 Voyager, equipped with a comfortable cabin and cargo compartment. The same Aviation Group offers another light, open, two-seat gyroplane M14 Scout, a favorite of the Russian market. All gyroplanes of the "Aviation Laboratory" are distinguished by a high level of production quality.

The approximate cost of Russian-made autogyros is about 2-3 million rubles. and depends on the equipment configuration.

In recent years, gyrocopters have attracted more and more attention from a wide range of aviation enthusiasts. They are used for tourism, patrolling, performing agricultural works, shooting videos and taking photos. Thanks to the minimum translational speed, it guarantees high quality photos and video. The ease of control of the autogyro makes it possible to train flying on it in the shortest possible time and at minimal cost. The undoubted advantage is the minimum required storage space. With folded rotor blades, the gyroplane can easily fit in a conventional garage.

Given all this, we can conclude that the autogyro has excellent prospects for becoming a mass vehicle.
