Antonow An-24 1966. - History
202b Section 1966-10-20
Few people know that Antonov An-24 aircraft were used in Poland not only in LOT Polish Airlines, but also by Military Aviation. It was a short period of time, but it was. The fact that the An-24 aircraft are used as LSD (flying command post) is also little known.
The Li-2, Il-12 and Il-14 aircraft put into service did not meet the users' expectations very much. Too weak power units, and above all the lack of pressure cabins for the crew and passengers caused significant operational restrictions. New planes had to be constructed, free from these drawbacks.
It wasn't that easy though. Military and civilian airplanes were built separately in the West. Only military aircraft were built at CCCP. The only office that dealt with the construction of a military-civilian plane was the office headed by Dr. Oleg Antonov. Officially, work on the new aircraft began in 1958. The goal was to develop a twin-engine transport aircraft that could also carry passengers.
While developing the transport plane, the latest trends in global aviation were used. It was noticed that transport planes, due to the use of propeller drive (with increasingly larger propeller diameter), have high cabin floors. While for passengers it is only a few degrees more gangway, for heavy loads requires lifting them to a significant height. Therefore, the right solution is to build planes in upper-lobed or even back-lobed systems. The floor of the cabin (hold) was much lower. This solution also caused the possibility of moving the engines under the wing, instead of placing them above or in front of the wing so far. These two basic solutions meant that servicing the engines on the ground became easier, because access to the most important devices required lower platforms and could even take place without them.
It was decided to use turboprop engines for propulsion, which have much more power than piston units, and at the same time consume less fuel than turbojet engines.
The first prototype of the new aircraft was flown on December 20, 1959, and the pilots were J. Kurlin and G. Łysenko. In April 1960, the first flight was carried out by a complete passenger version. In 1963, the aircraft entered service. Production was significant and in 1967 it exceeded 1,100 units. To this number we must add several hundred machines made in China under the designation Y-7.
The aircraft was built in many versions and variants. The basic version was the passenger version, designated An-24 W, taking 44-52 passengers on board. Here is a small correction; in Russian the letter W looks like Polish B, that's why there are descriptions about the Antonov-24 B version.
Numerous changes were made during the production of the An-24 aircraft. Among other things, in the back of the fuselage instead of one aerodynamic steering wheel two were used. Wing flaps have been modified. New AI-24 A engines with 2 x 1 902 kW were used.
The An-24 RW version is a variant of An-24 W, which is equipped with an additional RU-19-300 turbojet engine installed in the right nacelle, in place of the starting turbine used so far. This engine is a typical APU engine. This engine acts as a starter for turboprop engines and supports thrust during take-off or flight. With this solution, it is possible to operate aircraft at high-altitude airports, with a location up to a height of 3000 m above sea level and at an air temperature of up to + 30 degrees C.
The An-24 T version is a transport version, where a raised door is placed in the rear bottom of the fuselage. The aircraft was equipped with an electric ceiling crane and floor conveyor. The loading hatch can be opened during the flight.
The An-24 RT version is the An-24 T version equipped with an additional turbojet engine. An-24 aircraft have been in use in many countries. Still in 2005 many small transport companies used them.
An-24 for the Polish Army. 1966.
In 1966, state authorities decided to buy the first two An-24 W aircraft for the transport of important personalities (VIPs) and include them in the fleet served by the 36th Special Transport Aviation Regiment at Okęcie. On October 20, 1966, both aircraft were delivered to Poland and carried the designation An-24 W No. 67302801 nb 011 and No. 67302802 nb 012.
In the margin. VIP is the abbreviation of the angelic phrase Very Important Person - a very important person. Of course, this abbreviation is not surprising to anyone today and it is widely known. However, during communism it would be unthinkable to use such a phrase. It was said - personally important aircraft.
After a short period of use, as of April 3, 1969, these aircraft were transferred to LOT Polish Airlines, where they received the registration SP-LTO and the proprietary name of Odra and SP-LTP and the proprietary name of Poprad.
The photo shows the An-24 W aircraft SP-LTP "Poprad" registration at LOT Polish Airlines at the Okęcie airport. The plane in the old version of painting.
On 10.08.1968, the third An-24 aircraft in No. 87304504 nb 014 was delivered to 36 SPLT in Warsaw. As a curiosity we will say that nb 013 was not broadcast. This copy served the longest of all military An-24s. On 29.01.1977, he was transferred to LOT Polish Airlines and received registration SP-LTZ. After some time, he returned to service in the army, which rebuilt him into a flying command post. Its exploitation ended in 1992.
On December 24, 1969 (when the Polish Army had only one An-24 W), two new An-24 W were delivered to 36 SPLT No. 97305701 nb 011 (again) and No. 97305702 nb 012 (again). The first of these aircraft, on October 10, 1973, was transferred to LOT Polish Airlines, where it received the SP-LTT registration and the name Noteć. This second plane, on February 28, 1973, was a catastrophe.
Last An-24 In No. 97306007 nb 015, the army received on May 26, 1970, and after four years of operation, on June 27, 1974, it was transferred to LOT Polish Airlines, where it received the registration SP-LTU and the name Drawa.
In total, the Polish Army operated 5 An-24 W. aircraft.
An-24 in PLL LOT.
An-24 aircraft in the W version entered PLL LOT equipment in March 1966. There were about 20 of them, including planes handed over by the army. Replaced Li-2 and Il-14 aircraft.
They were operated mainly on domestic lines. At the beginning of 1990 began to be replaced by ATR-42 aircraft. Their final operation ended in 1992 and some of the machines were sold.
For almost 26 years, the An-24 W aircraft was the primary passenger aircraft on domestic routes, connecting the following airports; Okęcie, Gdańsk-Wrzeszcz, Gdańsk-Rębiechowo, Balice, Wrocław-Starachowice, Poznań-Ławica, Szczecin-Goleniów, Koszalin-Zegrze Pomorskie, Słupsk, Rzeszów.
Pictured PLL LOT planes, including An-24 W registration SP-LTA, CCCP machines, are terminating operation at PLL LOT.
It is well known that the first pilots were men; Daedalus and Icarus. But women know theirs. They have always flown on brooms. - That's a joke, of course.
- An-24 - basic passenger version. Intended for transporting people on short routes, up to 500 - 900 km. During production, more powerful AI-24 A engines with 2 x 1 902 kW were used.
- An-24 PT - an aircraft developed in 1964, adapted for flight in a tropical climate and use at high-altitude airports. As the first variant, it received a drive consisting of two 2 x 2,076 kW (2 x 2 820 hp) AI-24 T turboprop engines and a RU-19-300 turbine engine with 1 x 883 daN (1 x 900 kG) (APU) ). This engine acts as a starter for turboprop engines and supports thrust during take-off or flight. With this solution, it is possible to operate aircraft at high-altitude airports with a location up to 3,000 m above sea level and at an air temperature of up to + 30 degrees C. However, this variety has not entered production for the time being.
- An-24 W - airliner developed in 1966. Takes up to 52 passengers or 5,500 kg of cargo on board. The aircraft received AI-24 engines with 2 x 1 877 kW (2 x 2 550 HP). The aircraft was operated in Poland.
- An-24 RW - An-24 W aircraft with an additional RU-19-300 turbojet engine, as in the An-24 PT variant. The aircraft was developed in 1967.
- An-24 T - transport and landing. Developed in 1966. In the rear bottom of the fuselage, the cargo door is raised. The aircraft was equipped with an electric ceiling crane and floor conveyor. The loading hatch can be opened during flight and parachutists jump through it.
- An-24 RT - this version T is equipped with an additional turbojet engine.
- An-24 TW - it's practically a prototype of the An-26 aircraft. Developed in 1968.
- An-24 P - is a specialized version adapted to extinguish air fires.
- An-24 aircraft are still in use in the People's Republic of Korea (2014).
