The HESA Yasin is another in a long list of growing indigenous Iranian military-minded developments - this entry intended for training and light attack.
Despite sanctions imposed by the West for its nuclear ambitious, the Islamic Republic of Iran has managed to lay the ground work on a burgeoning military-industrial complex. This has led to a growing stable of homegrown products for its various military services as well as for interested foreign customers locked out of purchasing more complex, expensive Western technology. One recent product to emerge from the Iran Aircraft Manufacturing Industries Corporation (HESA) is the HESA "Yasin" - an all-modern Advanced Jet Trainer (AJT) offering with a secondary light-attack role planned.
The aircraft was first unveiled in October of 2019. Design work is attributed to the Iran Aviation Industries Organization (IAIO) with input from the Islamic Republic of Iran Air Force (IRIAF).
At its core, the aircraft is largely conventional in both form and function, consistent with other AJT offerings seen across the globe. This basic approach sees a tandem-seat cockpit with large-area clear-view canopy set behind a sharp nosecone assembly offering excellent vision. The fuselage is slab-sided and terminates with a short empennage capped by a single vertical tailfin and low-set horizontal planes. At the sides of the fuselage are mount the turbojet engines, aspirated outside the cockpit wall by a rounded intake and exhausted at the rear of the wingroot structure by way of circular port. The mainplanes originated from these wingroot structures and are low-mounted members with clipped tips and sweepback featured along the leading edge. For ground-running, a conventional tricycle (wheeled, retractable) undercarriage is featured.
Internally, the crew of two is given all-modern instrument panels as well as redundant controls. Both positions are set to feature ejection seats.
Dimensions of the aircraft include a running length of 40.1 feet, a wingspan of 34 feet, and a height of 13 feet. Empty weight is 8,600lb against an MTOW of 14,550lb.
Power is from 2 x Owj non-afterburning turbojet engines delivering 3,600lb of thrust each. This propels the aircraft to speeds of 620 miles-per-hour out to ranges of 560 miles and a service ceiling of 36,000 feet. Ferry range is 750 miles.
A light-attack role is planned for the development of this aircraft which will result in several hardpoints being featured under the aircraft. It is assumed this will comprise at least a single ventral fuselage centerline mounting as well as a pair of hardpoints under each wing mainplane member (for a total of five external hardpoints). Such aircraft typically carry an array of Close-Air Support (CAS) solutions such as gun pods, rocket pods, missiles, fuel tanks and the like.
