Ihsrc - Iran Helicopter Support and Renewal Company
In 1969, following the purchase of considerable number of helicopters from Italian company “Agusta” initial step to establish a helicopter support and maintenance unit, under the name of “ Iran Helicopter Company Joint Stock” was taken.
By purchasing a substantial number of helicopters from American “ Bell Textron “ in 1973, extensive planning to support new fleet was made and 3 main sections namely: (NMP), (HDMC) and (NICP) were defined for it.
Accomplishing this “Iran Helicopter support and renewal company” (IHSRC) became the largest helicopter maintenance center in the Middle East. Following the victorious Islamic Revolution in 1979, severance of ties with the USA and the imposed war inflicted to the new regime, loyal experts of “IHSRC” with the aim of supporting Islamic combatant in the battle fronts were able to reach self-sufficiency in maintenance and renewal of Iran helicopters fleet.
In the wake of these achievements,the responsibility to repair and support of 10 different models of military and civil helicopters,totally to 16 types of helicopters belonging to domestic companies,such as;”Iran Red Crescent Organization ”Iran Telecommunication Organizatio”,”Tavanir”and National Iranian Oil Company (NIOC), was given to “IHSRC”.
In 2002 “IHSRC” obtained necessary licences issued by “Civil Aviation Organization” to perform basic repairs and overhaul of civil helicopter models of 205, 212, 214 and 412.
Based on the repair schedules and for renewal and repair activities helicopters are placed in the proper jigs & fixtures.
All power transmission systems of helicopters such as Clutches, Main 42 and 90 degree Gearboxes are overhauled and tested at this workshop by sophisticated test equipments and are prepared for installation on helicopters.
Defective blades are paint stripped and dispatched to the blade shop for necessary repairs, painting and static balancing.
Producing all types of polymeric and composite aircraft fuel cell by research and development in Iran.
Design and manufacturing of jig & fixtures are part of main activity to build or rebuild cabin and tail booms for different structures. Experienced designers can assist in these cases to make subassembly and final assembly fixture for different needs.
After removal of cabin from fixture and transferring to the final assembly area, all parts and repaired components are reinstalled on helicopter according to the repair procedures and necessary adjustments and calibrations are carefully implemented to ensure the conformity of the performed repairs with aviation standards.
To assess the possibility of manufacturing process for metal and nonmetallic parts, preparation of production process, determination of required technology, selection of standard materials, preparation of workshop drawings and finally assembly plan for newly fabricated parts is part of expert engineers tasks in which by computer aides are responsible for such activities.
