 Abstract:
The HAL Light Combat Helicopter (LCH) is a multirole combat helicopter being developed in India by Hindustan Aeronautics Limited (HAL) for use by the Indian Air Force and the Indian Army. This project work aims to design and analysis of tow bar for light combat helicopter with the help of static analysis and buckling analysis. A tow hitch (or tow bar) is used for towing the helicopter from flight hanger to runway for ground testing and water testing. A device attached to the chassis of a vehicle for towing, or a tow bar to an aircraft nose gear. The main objective of this project is to design the tow-bar for LCH with better geometrical features to withstand the load and operating stresses built up during the operation, and to analyse the same for stress distribution during loaded condition Design and analysis for geometrical features of hitch type tow bar for wheeled version of light combat helicopter. Current version of the tow bar often encounters the problem of bending and breakage at various sections during towing, which has to be repaired or reworked frequently making it uneconomical to use. Hence the objective is to design the new tow-bar with better geometrical features to withstand the load during towing and to analyse the same for load bearing capacity and stress distribution in the equipment at various critical sections. Specifically the earlier version of tow-bar was designed using standards and manual calculations for stress analysis, the new version is designed and analysed using sophisticated software like UGNX8 and ANSYS 14.0 thereby increasing the quality of the equipment increasing worker safety and economical to use.
