The Tayyar MTH-3 "Ra'ad" (رعد, Thunder) is a unique Riysian triple-spool low-bypass turbofan engine, designed by Tayyar to power the TaH-26B deep modernization of the TaH-26 Saika interceptor. It was first flown on a TaH-26A testbed in 1978, and entered full scale production in 1984.
History
Development of the Ra'ad started in 1975, shortly after the TaH-26A, with its older Tayyar MTH-Kh turbojet engines, had entered service. The MTH-Kh provided superb high-altitude and high-speed performance, allowing the TaH-26 to exceed Mach 3 in ideal conditions, but was overly optimized for that role, leading to extremely poor low-level efficiency and power.
