Studies on Controllable Aircraft Rescue System for Passenger Aircrafts Using Multi Parachutes and Parafoils

Loss of lives due to fatal air accidents is an alarming problem faced by the aviation industry. There have been 88 fatal air accidents in the years 2010-2014 according to the IATA safety report. This clearly exhibits the fact that the present safety systems in aircraft are inadequate to save lives during mid-air emergencies. This paper presents a feasible solution to this problem with the use of controllable aircraft rescue system CARS involving the use of parachutes and parafoils. Parachutes are placed at the center, nose and tail sections of the aircraft which when deployed during a mid-air emergency to decrease the sink rate, provides stability and much-needed lift to the aircraft. Parafoils are attached to the wings of the aircraft through the fuselage which when deployed provides the much-needed control and enables safe navigation of the aircraft. Floats are provided at the bottom of the fuselage to reduce the force at impact in case of touchdown and also increase the time for which the aircraft can stay afloat in case of water landing. An analysis is performed to determine the size and diameter of parachutes required for aircraft of varying weights. The time of descent of the aircraft with parachutes from various altitudes is also determined. These results are summarized to exhibit the feasibility of the system.
