Feasibility and Spontaneity of Jetfans for Aircraft Fire Safety

Samanyu Raina, Vinayak Malhotra


Fires have been a serious threat yet to be comprehensively addressed in safe Air transportation. The fire occurrence in cabin is well etched by the unpredictable fire behavior transiting to larger high potential fires. The work investigates feasibility of automated ventilation jet-fan in the Aircraft to minimize fire spreading and enhance control action time thus reducing fire hazards. Present work proposes utilization of Jetfan as a potential fire safety system in aircrafts. Aircraft cabin is simulated as an enclosure with fire. Varying fire sizes are designed and placed at various location in the enclosure. The physical insight is drawn using heat feedback mechanism. Parametric simulations were carried out on the governing parameters like, HRRPUA (Heat release rate per unit area), volume flow, jet-fan size and location. The effectiveness of jet fan and optimum location for varying fires is thoroughly analyzed. The work is motivated by the need to have better fire safety for safer aviation programs.
