Project Summary

Aircraft, like any other machine are prone to malfunction. Despite the intensive maintenance and checks before each flight, an error can occur midflight and pilot may have to proceed for an emergency landing. In such a case, the aircraft may not be able to come to a halt on its own. Runway overshoot with a high speed may be quite devastating. Aircraft arresting systems are then employed to absorb the excess amount of kinetic energy and bring the aircraft to a halt. The aircraft arresting systems are of different types to deal with different types of Aircraft. While designing or suggesting an aircraft arresting system, structural damage is to be mitigated for aircraft as well as aircraft arresting system. This demands a keen analysis of the operating conditions and efficiency parameters such as deceleration rate. A detailed analysis must be carried out to ensure minimal damage to the aircraft in case of such an emergency. optimal barrier configuration is to be proposed to mitigate the damage especially to canopy, canards and such structures.

Project Objectives

Available barrier arresting system BAK-12 compatibility needs to be analyzed for aircraft with canards. For this purpose, initially barrier engagement analysis of JF-17 aircraft will be performed and compare with existing data to check the efficacy of the developed model. The same method will be then used to evaluate the structural damage of aircraft with canards in case of barrier engagement. The outcome of project will be finalization of the optimal barrier configuration which results in minimal structural damage.

Project Implementation Method

The analysis includes impact analysis under the multi body explicit dynamic analysis. For this purpose, complete aircraft with the barrier will be modelled in ANSYS. The energy absorbers will not be modelled but used to obtain boundary conditions for the tapes connecting the barrier. The aircraft will be modelled as solid geometry. The barrier and tapes are loaded in tension so bar elements will be used to discretize the barrier. The results obtained would include the force and stress contours for the aircraft and the barrier to propose the optimal barrier configuration.

Benefits of the Project

1. The safety culture will be promoted.
2. In case of any emergency, the damage resulting from aircraft arresting will be mitigated.

Technical Details of Final Deliverable

The force and stress contours resulting from barrier engagement will be presented. This will allow easier and faster repair works.
