HESA Simourgh (Persian: هسا سیمرغ) is an Iranian light transport aircraft unveiled on 19 May 2022. The aircraft is a modified version of the Iranian IrAn-140 turboprop airliner (itself based on An-140) and is suitable for transporting goods or even troops.
Development
According to Iranian official sources, the airplane is a modified version of the IrAn-140, which addresses some deficiencies of that design. According to pictures of the prototype Simourgh, there have been some changes to the wings, tail and fuselage compared to the IrAn-140 (the most notable difference being the cargo ramp added to the back of the aircraft).{{Cite web |last=Meier |first=Ricardo |date=2022-05-20 |title=Iran unveils 'indigenous' Simorgh turboprop |url=https://www.airdatanews.com/iran-unveils-indigenous-simorgh-turboprop/ |access-date=2023-04-29 |website=Air Data News |language=en-US}}{{Cite web |url=https://www.irna.ir/news/84763332/%D8%A2%DB%8C%D8%A7-%D8%B3%DB%8C%D9%85%D8%B1%D8%BA-%D9%87%D9%85%D8%A7%D9%86-%D8%A7%DB%8C%D8%B1%D8%A7%D9%86-%DB%B1%DB%B4%DB%B0-%D8%A7%D8%B3%D8%AA-%D9%86%DA%AF%D8%A7%D9%87%DB%8C-%D8%A8%D9%87-%D9%88%DB%8C%DA%98%DA%AF%DB%8C-%D9%87%D8%A7%DB%8C-%D8%AC%D8%AF%DB%8C%D8%AF%D8%AA%D8%B1%DB%8C%D9%86-%D8%AF%D8%B3%D8%AA%D8%A7%D9%88%D8%B1%D8%AF|title= (i.e. Is the Simorgh the same as the Iran-140?/A look at the features of Iran's latest aviation achievement) آیا سیمرغ همان ایران-۱۴۰ است؟/ نگاهی به ویژگی‌های جدیدترین دستاورد هوایی ایران |access-date=2023-04-29 |website=www.irna.ir}}

Design
= General characteristics =
As said earlier this aircraft is based on the IrAn-140 and shares lots of characteristics with it. The aircraft is 23m long, 25m wide (with wings) and 8m tall. It can carry 6 tons of cargo, has a range of 3900 km and has a max speed of 533 km/h. Simourgh is suitable for transporting cargo (Including 463L standard pallets, light vehicles and aircraft engines), evacuation of injured people (Able to carry 24 stretchers) or carry paratroopers. The minimum runway length needed for takeoff is 1450m and for landing is 900m.
= Difference with IrAn-140 =
Despite IrAn-140 which has trapezius-shaped wings, this aircraft has rectangular wings to give it more lift. Also the horizontal stabilisers went from V-shaped to completely horizontal. the back part of fuselage has also been modified. But the most notable difference is the cargo ramp added to HESA Simourgh.
= Engine =
HESA Simourgh is powered by two TV3-117 turboprop engines (probably reverse-engineered and modified version).
