The Ya Hossein Tazarve (also Taz-arv ( Persian تذرو), German: Fasan) is a two-seat training aircraft made by the Iranian manufacturer OWJ in the early 1990s. The trainer is produced as part of the Ya Hossein program and has so far only been used by the Iranian Air Force (Islamic Republic of Iran Air Force, IRIAF). Due to the western embargo, the IRIAF is forced to carry out its own developments for the training component as well. The machine is produced in the company OWJ, founded in 1987 and controlled by the IRIAF, which is also known as the OWJ Industrial Complex.
history
The first public demonstration of the Tazarve took place from October 30th to November 3rd, 2002 on the occasion of the air show on the island of Kish . The Tazarve was developed by a design team based in the Ya-Hossein works on the west side of Tehran 's Mehrabad Airport . The first project work began in the early 1990s and by 2003 three proof of concept machines had been completed. The first example, called "Dorna", was completed around 1995. Problems with production and maintenance led to a major redesign of the second machine. This example, called "Tondar", flew for the first time around 1998. Further changes to the fuselage, wings and on-board systems were implemented in the third machine, which was finally named "Tazarve" and has been in production since 1998.
The IRIAF is said to have ordered five pre-series aircraft and 25 series aircraft.
construction
According to the development team, the Tazarve is the first jet aircraft made entirely from composite materials, primarily from glass fiber and carbon fiber reinforced plastics. The wings, fuselage and tail section are manufactured separately and then screwed together. The wings and tail unit are made of synthetic resin-bonded material. All load-bearing structural elements are made from carbon fiber materials.
A single-shaft jet engine of the type J85 -17 propels the aircraft; the same engine is also used in the Cessna T-37 in Iran and 20 of them are said to come from existing stocks of the IRIAF. The replacement of this technologically obsolete engine with the Honeywell TFE731 -2A turbofan is in the planning stage . Since it is not possible to procure this in the USA, it is planned to include China as a supplier, as the TFE731 is also used in the Chinese K-8 trainer.
The avionics consist partly of older US elements and some parts that are produced in Iran itself, such as UHF / VHF radio equipment. Two Martin Baker Mk. 15 ejection seats are installed, which were actually designed specifically for use in the Pilatus PC-7 / PC-9 family of training aircraft.
