History:

During the war the Germans set up a number of assembly plants in Czechoslovakia for the of the production Messerschmitt Me 262. After the war the manufacturing infrastructure remained intact, so production could start up again for the new owners. This decision was taken remarkable quickly after the Soviet "Liberation" on the 27/5/1945

The first Avia S 92.1 was assembled at Letnany Research Institute in 1945 (PL-01), with the air frame coming from Avia and the engines from the repair works in Malesice (the Junkers Jumo 004 now called the M-04). The S 92's first flight was on the 27/09/46, with Avia's chief pilot Antonin Kraus in control. That same year on December 10th the CS 92 took to the air for the first time.

Delivery of the first S 92 to the Czech air force was on 42/6/1948. With twelve being made in all, nine S 92 and three CS 92 equipping the 5th Fighter Flight, until they were grounded for use as instructional airframes in 1951.

By the time Yugoslavia showed interest in buying the S 92, Avia was looking at closing down the production line to make way for new up to date aircraft and when Avia were given a licensed to make the Mig 15 (they were all ready making the Yak 23 as the S 101) the S 92 facilities were broken up.

After the Japanese military attach� in Germany witnessed trials of the Messerschmitt Me 262 in 1944, the Imperial Japanese Navy issued a request to Nakajima to develop a similar aircraft to be used as a fast attack bomber. Among the specifications for the design were the requirements that it should be able to be built largely by unskilled labour, and that the wings should be foldable. This latter feature was to enable the aircraft to be hidden in caves and tunnels around Japan as the Navy began to prepare for the defence of the home islands. Nakajima designers Kazuo Ohno and Kenichi Matsumura laid out an aircraft that bore a strong but superficial resemblance to the Me 262.

The Kikka was designed in preliminary form to use the Tsu-11, a very crude thermojet style of jet engine that was little more than a ducted fan with an afterburner. Subsequent designs were planned around the Ne-10 (TR-10) centrifugal-flow turbojet, and the Ne-12, which added a four-stage axial compressor to the front of the Ne-10. Tests of this powerplant soon revealed that it would not produce anywhere near the power required to propel the aircraft, and the project was temporarily stalled. It was then decided to produce a new axial-flow turbojet based on the German BMW 003. Development was troublesome, based on little more than photographs and a cut-away drawing, but a suitable unit, the Ishikawajima Ne-20, was finally built. By Summer 1945, the Kikka project was making progress once again and at this stage, reflecting the deteriorating war situation, the Navy changed the role of the aircraft to "special attacker", the term reserved for kamikaze weapons.

Compared to the Me-262, the Kikka airframe was noticeably smaller and more conventional in design, with straight (rather than swept) wings and tail surfaces. The triangular cross-section characteristic of the German design was less pronounced, due to smaller fuel tanks. The main landing gear of the Kikka were taken from the Mitsubishi Zero and the nose wheel from the tail of a Yokosuka P1Y bomber.

The Heinkel He 178 was the world's first aircraft to fly under turbojet power, and the first practical jet plane, the pioneering example of this type of aircraft. It was a private venture by the German Heinkel company in accordance with director Ernst Heinkel's emphasis on developing technology for high-speed flight and first flew on August 27, 1939 piloted by Erich Warsitz. This had been preceded by a short hop three days earlier.
In 1936, a young engineer named Hans von Ohain had taken out a patent on using the exhaust from a gas turbine as a means of propulsion. He presented his idea to Heinkel, who agreed to help develop the concept. Von Ohain successfully demonstrated his first engine in 1937, and plans were quickly made to test a similar engine in an aircraft. The He 178 was designed around von Ohain's third engine design, which burned diesel fuel. The result was a small aircraft of conventional configuration and construction, with a metal fuselage and high-mounted wooden wings. The jet intake was in the nose, and the plane was fitted with taildragger-style undercarriage. On the first flight, the main gear was fixed, but was later made retractable.

The aircraft was an outstanding success � although just a flying testbed, it was faster than any piston engined military aircraft of the day that were then in regular squadron service, having reached a maximum speed of 403 mph (650 km/h) and a cruising speed of 363 mph (585 km/h). Projected maximum speed for a production aircraft was to be 435 mph (700 km/h), a speed not reached in combat until 1944, but easily exceeded by the third prototype of the Messerschmitt Me 163, a rocket fighter, in August 1941. On November 1, 1939, Heinkel arranged a demonstration of the jet for the Reichsluftfahrtministerium ("Reich Aviation Ministry", RLM), where both Ernst Udet and Erhard Milch watched the aircraft perform. However, due to the conservative approach to aircraft design then favoured by both men, no official interest in the concept was shown. Nevertheless, Heinkel was undeterred, and decided to embark on the development of a twin-engined jet fighter, the Heinkel He 280 as a private venture using what had been learned from the He 178.

The He 178 was placed in the Deutsches Technikmuseum ("German Technical Museum") in Berlin, where it was destroyed in an air raid in 1943.

Stvarno ceski!

Evo jos par slicica:

Sve imas ujkaalberte!

Ako ti trebaju jos neke slike slobodno reci.

Hvala Ujkaalberte. No nisam ja neki dugogodisnji poznavalac pa da sad nesto specijalno trazim. Ako imas jos neke fotke Me262 (bilo sta, moze i iz svetskih muzeja, iz rata, itd).
Nemacki avioni su mi odmah privukli paznju svojom posebnoscu, pogotovo projekti pred kraj rata. Covece, oni su zaceli gotovo svaki moguci leteci koncept. Fantasticni konstruktori i strucnjaci. Naravno nije sve uspevalo, ali kad nesto radis prvi i u brzini (rat, presija) naravno da ima promashaja.

Kad smo kod Me 262 (i varijanti), zanima me (postovali ste ovde Ti i Pilot), jednun varijantu koja ima mnogo vecu zastakljenu kabinu (kao da je dvosed???). Sta je to?
Takodje Pilot je postovao crtez sovjetske varijante - da li ima mozda fotki te sovjetske varijante???

I jos jedna stvar, bilo bi vise scientific (naucno ili bolje receno: iscrpnije) da se u tekstu pre fotki (ako vec ne moze u samom imenu fotke tj fajla) objasni konkretno o cemu je rec; mislim na sledece podatke (ne moraju svi, ali oni koji se znaju): varijanta i podvarijanta aviona, njegove oznake, pripadnost grupacij, mozda serijski broj, lokacija gde je fotografisan ili baziran, muzej, aerodrom, datum ili makar godina, itd.
Tako se lakse onda mogu svrstavati fotografije po nekom kljucu koji svako po volji bira.

Ee, da! Niko nishta ne odgovori  u vezi postovanih slika Me 262 HG Early variant i Me 262 HG III, da da neku informaciju vishe. Ja sam nasao samo te lepe radove. E kad bi bilo nekih njihovih crteza, i nekih tekstova o tim projektima.

Vidi, vidi, nasi su hteli da kupe.
Haaa! Vredelo bi nacrtati jednog sa nasim tadasnjim nacinom oznacavanja - bas bi bila fora, a obaska da ga je imati u Flight Simulatoru takvog. Issss!

Imam slike a i stavio sam vec, kad su nasi isli da ga probaju
