Hindustan Aeronautics Limited (HAL), which has been tasked with designing and developing the Indian Multi Role Helicopter (IMRH), a medium-lift helicopter for the Indian Armed Forces, is eager to begin work on India’s tiltrotor aircraft programme in the mid-next decade, as tiltrotor technology is rapidly maturing and will soon be as affordable as current helicopters.

Tiltrotor technology as name suggests can tilt and direct the thrust they generate towards the ground to allow it to take off and land vertically, and then adjust their positions to send that thrust backwards in forward flight, much like traditional aircraft propellers is biggest revolution in helicopter technology in last 40 years but the technology is still niche and expensive for which HAL’s The Rotary Wing Research & Design Centre (RWR&DC) and Aircraft Research & Design Centre (ARDC) are working together to create multiple flexibility studies.

HAL believes that the tiltrotor engine will be the most difficult to overcome, but as more OEMs invest in the research and development of such engines for both military and civilian space applications, availability of such engines will increase by the end of this decade.

Tiltrotor technology allows any aircraft to land and take off like a helicopter and then flies like an airplane. No Helicopter can compete with a tiltrotor when it comes to speed and range.
