19-397: The runway was originally 10,006 ft × 150 ft (3,050 m × 46 m) but was shortened to 5,899 ft × 150 ft (1,798 m × 46 m); in 2012 it was re-extended to 10,006 ft × 150 ft (3,050 m × 46 m) and is maintained year-round. It has a pavement overlay (from 1998), new approach lights and a new taxiway. The airport is

38-506: A new engine based on the General Electric J85-GE-21B named "OWJ" and presented it at a defense exhibition on 22 August 2016. The Owj engine has been used in several Iranian products like Kowsar , Saeghe and Azarakhsh fighter jets or Yasin training jet. Data from Related development Comparable engines Related lists HESA Kowsar The HESA Kowsar ( Persian : کوثر , also spelt Kosar )

57-538: A range of 93 km (57 miles) that can engage two targets simultaneously. There were reports of a crash by an Iranian-operated F-5 days after the Kowsar's existence was announced. On November 26, 2018, Brigadier General Abdolkarim Banitarafi, head of Iran Aviation Industries Organization (IAIO), announced that Iran was ready to export the HESA Kowsar jet and had agreements with Russia, China and Indonesia. The Kowsar, like

76-519: A rear-mounted fan for improved fuel economy . The J85 was originally designed to power a large decoy missile, the McDonnell ADM-20 Quail . The Quail was designed to be released from a B-52 Stratofortress in-flight and fly for long distances in formation with the launch aircraft, multiplying the number of targets facing the SA-2 surface-to-air missile operators on the ground. This mission demanded

95-602: A small engine that could nevertheless provide enough power to keep up with the jet bomber. Like the similar Armstrong Siddeley Viper being built in the UK, the engine on a Quail drone had no need to last for extended periods of time, so therefore could be built of low-quality materials. The fit was a success on the Quail, but again like the Viper it was later built with normal grade materials and subsequently used to power small jet aircraft, including

114-645: Is a very old American war plane (it was manufactured in the ‘50s). It is from the F-5 class of jets which has not been in use for decades". However, according to Northrop Grumman , "approximately two-thirds of the original production F-5s remain operational in 26 countries, including the United States." According to Douglas Barrie, military aerospace senior fellow at the IISS , the Iranians have possibly made upgrades and changes to

133-569: Is an Iranian fighter jet based on the American Northrop F-5 . The aircraft is equipped with new fourth generation avionics in combination with an advanced fire control system . Western analysts have described the plane to be inefficient as a weapon, but having potential for training a new generation of Iranian fighter pilots. According to the Iranian state-media, this fighter jet has "advanced avionics" and multipurpose radar, and it

152-409: Is capable of generating up to 2,100 lb f (9.3 kN) of dry thrust, or more with an afterburner. At full throttle at sea level, this engine, without afterburner, consumes approximately 400 US gallons (1,500 L) of fuel per hour. At cruise altitude and power, it consumes approximately 100 US gal (380 L) per hour. Several variants were produced. The most advanced variant in

171-545: Is one of GE's most successful and longest in service military jet engines, with the civilian versions having logged over 16.5 million hours of operation. The United States Air Force plans to continue using the J85 in aircraft through 2040. Civilian models, known as the CJ610 , are similar but supplied without an afterburner and are identical to non-afterburning J85 variants, while the CF700 adds

190-746: The Northrop T-38 Talon , Northrop F-5 , Canadair CT-114 Tutor , and Cessna A-37 Dragonfly light attack aircraft. More recently, J85s have powered the Scaled Composites White Knight aircraft, the carrier for the Scaled Composites SpaceShipOne spacecraft, and the Me 262 Project . The basic engine design is quite small, about 17.7 inches (45 cm) in diameter, and 45.4 inches (115 cm) long. It features an eight-stage axial-flow compressor powered by two turbine stages, and

209-822: The Saegheh and the Azarakhsh , was made based on the frame of the American F-5 . The Kowsar is produced in single and two-seater variants. On 25 June 2020, the Iranian Ministry of Defence and Armed Forces Logistics announced that three new Kowsar aircraft had been delivered to the Islamic Republic of Iran Air Force , in a ceremony in Esfahan . The images published showed the aircraft painted in non-combat colours. Israel 's defense minister Avigdor Liberman told press that it

228-507: The J85 series is the J85-21 model designed specifically for the F-5E/F during its development process. The J85-21 design replaces AM 355 chromium nickel molybdenum stainless steel alloy, used by previous J85 models for compressor rotors and blades, with a titanium alloy. Its inlet diameter was increased from 17.7 in (45 cm) to 20.8 in (53 cm), and it included an added stage ahead of

247-596: The Kowsar in the Defense Industry Day event celebration in Isfahan . HESA Kowsar has 7 hardpoints with a total capacity of 3200 kg (7054 lbs) of armaments and also has a 20 mm cannon. It can carry up to 4 air to air Fatir missiles, a reverse engineering of Sidewinder missiles, or twelve 250 kg (550 lbs) bombs or five 450 kg (1000 lbs) bombs or two 900 kg (2000 lbs) bombs. Kowsar has an Italian Grifo radar (a Chinese model or its domestic production has been used) with

266-487: The airport which is still used for local glider operations. The two southern runways (04/22 and 15/33) were truncated by the southern boundary fence parallel to the main runway and one (15/33) was used as a drag strip and the other (04/22) is an industrial area but the current status is unknown. The top of 04/22 is now taxiway 'B' which was where the ready hangars for the McDonnell CF-101 Voodoos were, leading to

285-446: The base 8-stage compressor for a total of 9 stages. Its multiple disk rotors were replaced with a single-spool rotor, thus improving dry thrust to 3,600 lb f (16 kN) and wet thrust to 5,000 lb f (22 kN) while reducing mechanical complexity along with the weight gain of the J85-21 model. More than 12,000 J85 engines had been built by the time production ended in 1988. The Iranian Ministry of Defense constructed

304-477: The home base of the Department of Natural Resources and Energy Air Tanker Operations, and Forest Protection Limited, who own and operate the air tanker fleet. In addition, a General Electric J85 engine test facility is located at the airport. The airport is the former site of CFB Chatham , a military air base, which closed in 1996, after military units were moved to other bases. There is one abandoned runway within

323-632: The threshold of runway 27. Since the closure of the airbase, the airport only has one runway operational for aircraft and one closed runway for glider use only. The three former runways were paved and marked to indicate their closure or non-use. General Electric J85 The General Electric J85 is a small single-shaft turbojet engine. Military versions produce up to 3,500  lb f (16  kN ) of thrust dry; afterburning variants can reach up to 5,000 lb f (22 kN). The engine, depending upon additional equipment and specific model, weighs from 300 to 500 pounds (140 to 230 kg). It

342-512: Was "100-percent indigenously made". It also uses digital data networks, a glass cockpit , heads-up display (HUD), ballistic computers and smart mobile mapping systems. On November 3, 2018, there was a ceremony that inaugurated the launch of the Kowsar assembly line at the Iran Aircraft Manufacturing Industries Company (HESA) with at least seven being made. President Hassan Rouhani was present as he inspected

361-493: Was a "natural reaction to an economic crisis", adding "[t]he Iranians are feeling very pressured by the continued US sanctions and in reaction they are coming out with these things, but we also shouldn’t dismiss it". Ofir Gendelman , spokesperson of the prime minister's office tweeted "The Iranian regime unveils the Kowsar plane and claims that it is ‘the first 100% locally-manufactured Iranian fighter jet'. It boasts about its offensive capabilities. But I immediately noticed that this
