After the last talk about aircraft engines, we return again to the Jizera Mountains Technical Museum. The restorer and a great connoisseur not only of the historical engine Pavel ercl nm, this time he presents some design, he has since turned out to be an extraordinary double.

Such is the power unit, which was created to ride before the Second World Wolf, but subsequently was assembled by you in the travel and research and training aircraft Luftwaffe Heinkel 116-B.

from the Hirth 508 engine. Air-cooled eight-cylinder to V in noise 60 …

It is an air-cooled inverted eight-cylinder V, Hirth 508, a German aircraft engine, which, in addition to the ring rings and the piston, does not have a single sliding bearing. Everything in that engine is mounted on lifts, needles, ball bearings, and therefore the engine had very mechanical resistance, the ercl engine explains and the bell was added to it, because the situation on the rolling bearings, which by their nature are always The coulter is not sliding, so the lightened cogwheel made a typical ringing sound.

Paul ercl shows the place where the stela damaged the ribs but did not penetrate the wolf.

This concrete exposition also bears evidence of combat deployment. His block is covered with a machine gun stela in several places. The evident bag engine lasted bet dl and pistol. According to the Technet podcast, Pavel ercl explains how it was possible that the engine did not fail.

This time we first talked about aircraft engines where we left off last time: for the extremely interesting DaimlerBenz engine from the Messerschmitt Bf 109 fighter aircraft. The original effort to keep the engine as light as possible ultimately had one great by-product: a very simple overhaul.

Pavel Pavel’s engine points to a gear that acted as a large nut ….

Pull the nut, which resembles a gear, behind the wolf to the entire crankcase. Also, there are no clamps or bolts on the engine that would pull the head and block to the crankcase, explains Pavel Ercl, and on the rail section shows the nuts seated around the fist, they were loosened by a special tool, resembling a pinion.

The gear shows a gear that acted as a large nut. It allowed a special clamp, so it was very easy to remove the entire wolf unit from the engine.

When it was allowed, the whole wolf unit, including the valve and the bag, pulled down (it is a monoblock, where the wolf and the head form one unit) and only the connecting rods with fists looked out of the engine.

The flight mechanics then just exchanged piece by piece. A new wolf unit was taken from the box, which was fitted with a bag shaft, slid on the wolf and pithla to the crankcase. The same thing happened on the other side, and it is also assumed that within two hours of work, the wolves were finished.

It was then easy to remove the valves and valve seats from the dismantled bellows unit. After the exchange, the unit with new fists was ready to be sent to the front.

It is our time to break away from the fast engine. In the Technet podcast, we explain their fundamental limits, which eventually led to the production of jet engines. She also had her ways and blinds.

Soviet jet engine Klimov VK-1, its development was based on British …

German jet engines were in a completely different way than the British. The British developed the so-called radial jet engine, only a relatively large compressor. The air flow is relatively complex due to its construction and did not have a long life in the air force. The Germans began to develop what is actually used to this day, an axile jet engine. The air that passes through the engine is basically not at all.

Soviet turbocharged engine Klimov TV2-117 for helicopters, the first of its kind, built in the Soviet Union. Its design dates back to 1960. This engine is the most mass-produced helicopter power unit in the world. Accumulated more than 100 million hours in operation. Axial compressor, maximum input power 1,300 kW. The contract engine probably came from a Mi-8 helicopter, in which Viera Huskov, the wife of President Gustav Husek, died on June 20, 1977.

Where does the engine grow to the limit? Do current jet aircraft have so many jet engines? And how is a jet engine for a helicopter? According to the Technet podcast, this will be a new topic.
