Turbomeca and Hindustan Aeronautics Limited (HAL) will soon be flight testing their codeveloped 1,200-shp Ardiden 1H (or Shakti, under its Indian designation) turboshaft engine, the French partner announced last month. Certification is pegged for this fall, with deliveries to begin shortly thereafter. Initial applications will be upgraded military versions of the twin-turbine HAL Dhruv. The engine made its first ground run in October 2005.
