SP Guide Publications puts forth a well compiled articulation of issues, pursuits and accomplishments of the Indian Army, over the years
I am confident that SP Guide Publications would continue to inform, inspire and influence.
My compliments to SP Guide Publications for informative and credible reportage on contemporary aerospace issues over the past six decades.
Defence Metallurgical Research Laboratory of the Defence Research and Development Organisation (DRDO) has developed Single Crystal Blades Technology and supplied 60 of these blades to Hindustan Aeronautics Limited (HAL) to support their indigenous helicopter development programme. It is part of a programme to develop five sets (300 in number) of Single Crystal High Pressure Turbine blades using a nickel-based super alloy. The supply of remaining four sets will be completed in due course. Military helicopters fly in very tough conditions and hence need compact and powerful aeroengines for reliable operation under extreme conditions. To achieve this, state-of-the-art Single Crystal Blades having complex shape and geometry, manufactured out of Nickel-based super alloys capable of withstanding high temperatures, are used. Very few countries in the world such as the United States (US), the United Kingdom (UK), France and Russia have the capability to design and manufacture such Single Crystal components. Defence Minister Rajnath Singh has congratulated the team.
