The glider differs significantly from an airplane in its elongated wing (i.e., a larger aspect ratio) with a slender and streamlined fuselage. Some gliders have a wing aspect ratio of more than 30 and tend to be designed in the pilot's reclining cabin in order to reduce the cross-sectional area of the fuselage. The surface of the fuselage is smooth, and even waxed, so as to improve the lift-to-drag ratio of the glider and reduce the glide angle in gliding flight. Some gliders also have airbrakes on their wings that can be manipulated to open to increase drag if necessary, or to adjust the glide angle when landing to land in order to land accurately at a designated location.

Of course, Zhao Yun's purpose was for them to learn the glider through guò and then enter the tutorial of the power glider.

The powered glider is equipped with a small auxiliary engine that can take off on its own without external traction, and when it reaches a predetermined altitude, the engine is turned off for basic gliding flight. Powered gliders increase the efficiency and safety of training flights.

In order to give full play to the population advantage of China, Zhao Yun put the flight training level, one grade, the first level can only fly gliders, the second level is flying power gliders, the third level is flying ultralight aircraft, and the fourth level is the real aircraft, but it is still the Fokker fighter of World War I.

The Fokker fighter has been introduced before, so let's take a look at the third stage of ultralight aircraft.

The empty weight of an ultralight aircraft is only one or two hundred kilograms, most of which are composed of aluminum alloy and nylon cloth, balsa wood, hard foam and other materials, and then installed with a small engine with dozens of horsepower to fly, most of which are no cockpit or half cockpit type, and are composed of simple flight instruments and engine instruments. Most ultralight aircraft can be disassembled in bulk and assembled when they arrive at the place of use. When leaving the factory, all parts and components are packed in the packing box, and after being sent to the designated place, the whole machine can be assembled within one day. Another characteristic of ultralight aircraft is that there are very few ground crews, and they are generally pilots and ground crews, and only in a few cases do they need help.

In China, where there are only a few hundred pilots, the ground crew is a headache, which is one of the important reasons why Zhao Yun chose ultralight aircraft.

The take-off and landing distance of ultralight aircraft is short, generally only tens or hundreds of meters, and some aircraft are only more than ten meters. Due to the short running distance and the small amount of space required, this brings a lot of convenience to the use and promotion of the aircraft. Ultralight aircraft do not have high requirements for ground conditions, and can take off and land from dirt roads, grasslands, people, beaches, fields and other flat and open places.

As for the engines that have always restricted the development of Huaxia aircraft, since there is no need for the most advanced high-power engines, those engines that were eliminated by Germany and France during World War I were purchased back by European personnel at the price of "broken copper and iron", and after repair, imitation, and large-scale installation began.

The ability of the Chinese people to draw inferences from one case is recognized by all countries in the world, Zhao Yun was only responsible for the introduction of engines, and took out a lot of money to provide them, and flying enthusiasts in Fujian, Nanjing, Shanghai, and other places successively developed ultralight aircraft for various purposes, such as water ultralight aircraft, amphibious ultralight aircraft. There are mainly "bees", "eaglets" and so on.

The "bee" is a "knockoff" made by Zhao Yun in imitation of a helicopter, and in aviation industry terms, it should be called an ultralight rotorcraft, not a helicopter.

An ultralight gyroplane is actually a flying machine between a helicopter and an airplane, which, in addition to the rotors, has a pair of propellers placed vertically to provide forward power, and a smaller wing in the rear section to provide partial lift in flight. The biggest difference between a gyroplane and a helicopter is that the rotor of the gyroplane is not connected to the engine transmission system, and the engine does not provide lift for the aircraft by driving the rotorcraft, but in the process of the rotorcraft flight, the rotor is blown by the front airflow to rotate to generate lift, like a windmill, the rotor system is only driven by its own power when starting, which is called pre-rotation, and is driven by air force after takeoff; The rotors of the helicopter are connected to the engine transmission system, which can not only generate lift, but also provide flight power, like an electric fan. Since the rotor is self-rotating, the torque transmitted to the fuselage is small, so the gyroplane does not need the tail rotor like a single-rotor helicopter, but it is generally equipped with a tail to control the flight.

In flight, the most obvious difference between a gyroplane and a helicopter is that the rotors of the helicopter are tilted forward, while the rotors of the gyroplane are tilted backwards.

The "Kitty Hawk" is an ultra-light delta-wing aircraft, also known as a suspended delta wing, with a rigid basic structure, with a movable overall wing surface exercise, and a backup umbrella for safety rescue. As long as you have a suitable hillside and run 5-6 steps against the wind, you can soar into the sky. It is composed of four parts: tower, keel, tripod and sling, and each part is connected by steel cables.

The ultralight delta wing aircraft is equipped with more power plant than the delta wing, so that it can adapt to a more complex flight environment, stay in the air for a longer time, and can take off and land on flat ground, which can be called an aircraft in the true sense.

A power delta wing is a suspended glider equipped with an engine that can fly at a maximum altitude of 4,000 meters and a cruising speed of up to 300 kilometers. Behind the seat are the aero engines and propellers, and the pilot mainly relies on pushing and pulling the joystick to control the "big bird".

These "copycat" planes are only pediatric for the Fujian Aircraft Institute, which can even manufacture real aircraft, so there is no difficulty in manufacturing.

This sentence of "not difficult" made the people of Fujian Aircraft Factory regret it for a long, long time. because

Ultralight delta-wing aircraft do not exceed 115 kilograms for a single seat and 150 kilograms for a two-seater, so Zhao Yun also moved the idea of carrying them onto a warship and forming an "aircraft carrier".

As a result, Zhao Yun, who was not short of money, placed 4,000 orders in the first batch. almost smashed several bigwigs of the Fujian Aircraft Factory on their backs happily.

Airplanes are being built slowly, and the training of pilots is even more urgent. Zhao Yun looked to the north again.

Outer Mongolia is now almost a vegetable market, and people from all walks of life are flocking to Kulun. Zhao Yun just listened to Timur's ten-minute report, and his head hurt.

"Drag!" Zhao Yun listened in a fog, but still sorted out a general idea.

In early April, the Naadam Conference held in Kulen, or the Kulen Power Struggle Conference, at the meeting, at the meeting, at the meeting, in general, there were a few points.

Japan, the representatives of White Russia in the Far East, in order to keep Mongolia in check with the Soviet Russian army in the Far East;

Britain and the United States also gave a lot of benefits to Mongolia for not throwing themselves into the arms of Soviet Russia;

Beiyang Jixian County, in order to recover Mongolia, will make up for the merits and establish its own prestige in reputation;

The king of Mongolia was entangled in order to regain his lost territory;

In order to win over allies, Feng gave a knife to the direct family;

Western Xinjiang, in order to unite Mongolia against the encroachment of Soviet Russia;

Inner Mongolia unites Mongolian tribes...... Well, this is a hodgepodge, this is politics, Zhao Yun doesn't understand, for things that don't understand and are nerve-wracking, Zhao Yun has always run as far as he can.

Cherish life and stay away from ......

However, just as he was about to lie down and rest, Zhao Yun, who had slept beautifully, received a confirmation document and an urgent text from Timur.

Looking at these two documents, Zhao Yun, who was about to sleep, was so frightened that he even dropped the quilt on the ground.

It's not that Zhao Yun is timid, it's that Zhao Yun has too little experience.

It was confirmed by the personnel of the captured 35th Division, the relevant documents, and the "own people" of many parties in Soviet Russia, that the Fifth Army of Soviet Russia was under the jurisdiction of: the 1st Smolensk Infantry Division, the 4th Petrograd Infantry Division, the 1st Siberian Infantry Division, the 2nd and 5th Infantry Divisions, the 24th Simbirsk Iron Division, the 25th, 26th, 27th, 29th, 30th Infantry Division, the 31st Turkestan Infantry Division, the 35th Siberian Infantry Division, the 40th, 51st, 59th, 62nd Infantry Divisions, Yenisei Infantry Division, Third International Infantry Division, 13th Cavalry Division and Mixed Cavalry Division.

In May 1920, the army group came under the command of the deputy commander-in-chief of the armed forces in charge of Siberia, and was later incorporated into the Eastern Siberian Military District.

Commander of the Army, February 1920 – August 1921, Matyasievich; Ubolevich from August 1921 to August 1922;

The army was formed in the years of the Russian Civil War and foreign armed intervention, and was first formed in August 1918 in the Eastern Front. It consisted of a combat army that quelled the rebellion of the Czechoslovak Army in the Kazan region.

Originally, Zhao Yun believed that the 35th Division had been given a devastating blow and at least half of the Fifth Army had been wiped out. But I wonder why they didn't catch the commander of their army group?

As a result, I sent someone to check it, and this check got the above content, and when I saw the number of the troops under the Fifth Army, I was so frightened that Zhao Yun, who was just a little white-collar worker in later generations, had weak legs.

Zhao Yun's first reaction was to scold, the eighteenth group army in later generations only had a few divisions, how could Lao Maozi have so many division-level establishments in a group army?

And the 35th Division, which was originally thought to be destroyed, was resurrected again. There has always been a tradition of "shadow troops" in the Soviet Russian army, and one regiment left by the 35th Division in the Mengxi Expeditionary Army has slipped through the net, and this time the backbone and recruits from various brother units have been brought in to form the 35th Division.

The commander of that army group, Matyasievich, was not caught, nor because he had fled, but was transferred to another army group, or rather a combination of two armies, the Far Eastern reinforcements consisting of the 1st Revolutionary Labor Army and the 3rd Army.

From October 1919 to January 1920, Matyasievich was commander of the 1st Revolutionary Labor Army.

The predecessor of this army was the 3rd Army of Soviet Russia, which consisted of the 1st, 2nd, 3rd, 4th, and 5th Ural Infantry Divisions, the 29th, 30th, 51st, and 62nd Infantry Divisions, the Ural Infantry Division, the 10th Cavalry Division, and 1 special service brigade.

First formed in June 1918, it consisted of corps and units of the Eastern Front fighting against the Czechoslovak rebels and White Guard detachments in the Perm, Yekaterinburg (Sverdlovsk) and Ishim regions during the period of the Russian Civil War and foreign armed intervention.
