Yakovlev Yak-23
The Yakovlev Yak -23 (Russian Яковлев Як -23, NATO code name "Flora" ) from the Soviet design bureau Yakovlev was a Soviet fighter aircraft. She appeared about the same time as the MiG- 15, but their numbers could not reach far.
Development and use
It was developed from the Yak- 19 with spindle-shaped hull. As drive a more powerful RD -500 turbojet engine was provided. Since this was larger than the RD -10F of the Yak- 19, was installed as the types Yak- 15 and Yak- 17 in the front and middle part of the fuselage towards the rear expiring.
Flight testing was carried out from June to September 1947, MI Ivanov. Series production ran from March 1948 to 1950 and ended after the 310th machine. A school version called Jak - 23UTI 1949 and appeared in a few copies, identified by the additional front pulpit. The Yak- 23 was flown by the Soviet Air Force, but also exported, such as Bulgaria.
In Poland, the pattern of the Yak- 9P used to date, replaced in 1951 with piston engine and was the first jet aircraft used the army. In the first line she stood there until 1956, after which it was used for a time as a training aircraft. 1957 was won by a Polish Yak- 23, a world record when she min 17 sec increased to 6,000 m in Figure 3. Under the name of S -101 ( Stihaci letadla = fighter plane ) flew 12 machines in Czechoslovakia. But intended to license- it was not because the Soviet Union, now the much more advanced aircraft MiG -15 offered to licensed construction.
The fighter pilot Romania were also equipped with this type and even developed its own two-seater training version, the Yak- 23D.C. ( Doubla Comanda = double tax), the possessed, unlike the conventional Jak - 23UTI a continuous smooth cockpit.
The following series Yak- 25, Yak- 30 and Yak- 50 remained all experimental fighter aircraft and were not built in series. One can visit today, per a Yak- 23 in the Warsaw Military Museum, the Aviation Museum Prague / Kbely as well as in the Central Museum of the Russian Air Forces in Monino.
The Yak- 23 was simple and rugged construction, during maintenance, the entire front fuselage could be removed to facilitate access to the engine. The aircraft consisted entirely of metal, the hull was covered with a self-supporting shell. The verses existing with a laminar airfoil were cantilevered and in mid-wing design. Due to their small thickness, no fuel tank could be accommodated in them, so that the Yak- 23 usually mitführte two external tanks on the wing tips. The nose landing gear and the wheels of the main landing gear drove a while in flight in the fuselage, struts resting in the wings. The pilot sat in a non hermetisierten cabin and was protected in the neck by an 8 -mm armor plate as well as from the front by a front disc of 57 mm armored glass. The equipment of the model included an ejection seat, a RSI -6M -1 radio and a radio compass half. The use of the Yak- 23 could also be made of dirt from grass runways due to the robust chassis.
