“…When the aircraft reaches a certain altitude in the air, the inerting system begins to release nitrogen into the center fuel tank. Many scholars at home and abroad have carried out different types of research on the performance of fuel tank inerting systems [7][8][9][10][11].…”

This paper introduces the composition and function of civil aircraft fuel tank ventilation and inerting systems. The ventilation and inerting systems are closely related to the fuel tank, so there is a cross-link between the two. Given the fuel spillage phenomenon of the surge tank, which occurs during the climb of the aircraft due to the imperfect design of the fuel tank vent system, the mechanism of the fuel spillage and the role of the inerting system in the fuel spillage process are analyzed. Meanwhile, the optimization measures of the fuel tank vent system are introduced, which can provide experience reference for the cross-linking design of the fuel tank system and inerting system of other aircraft.

“…The fuel tank with a large amount of fuel in the aircraft is prone to involving fire and explosion hazards during operation, parking, and maintenance, resulting in disastrous consequences [1,2]. The upper space of the fuel tank gathers a large amount of combustible oil and gas mixture, which is a potential safety hazard that requires measures to prevent an explosion.…”

RP-3 aviation kerosene is widely used in China, and the critical explosible oxygen concentration (COC) and lower explosion limit (LEL) are important parameters concerned about aviation safety. The COC and LEL characteristics of RP-3 aviation kerosene vapor/O2/N2 mixtures at different initial temperatures and pressure were investigated experimentally. The LEL for RP-3 vapor/O2/N2 mixtures ranges from 0.5 vol% to 0.6 vol%, with the ambient pressure ranging from 40 kPa to 100 kPa, temperature from 60°C to 150°C, which is almost unchanged. The COC decreases as the temperature and pressure increase, and the COC of RP-3 vapor/O2/N2 mixtures is 9.7 vol% under the pressure of 100 kPa and 150°C. The suppression performance of N2 on the RP-3 vapor/O2/N2 mixtures was discussed, and the suppression performance model was defined in this paper, the suppression performance on COC condition is about 77%.

“…After several years of development, the Hollow Fiber Membrane On-Board Inert Gas Generation System (HFM-OBIGGS) has become the most commonly used inerting technology. For instance, the F-22, F-35, Boeing 737, Boeing 747, and Airbus A320 all employ this technology [7,8]. However, practical application has revealed several issues with this technology.…”

Oxygen-consuming inerting technology is expected to be the primary method for suppressing aircraft fuel tank fires and explosions in the next generation, with the catalytic reactor serving as its core component. However, the catalytic properties of the developed catalyst have yet to be thoroughly studied, and a primary reaction kinetic equation is needed to support further investigation of the reactor. Thus, this study focuses on the performance of the developed catalyst for RP-3 fuel vapor, with a test bench built to analyze its reaction kinetic characteristics. Initially, we tested the steady-state variation in the fuel vapor concentration (FVC) with fuel temperature and fitted an empirical equation, providing fundamental data for subsequent experiments. Subsequently, we studied the impact of critical parameters, such as the FVC, oxygen concentration (OC), CO2 concentration, and reaction temperature, on the reaction performance. The results demonstrate that the reaction rate is positively correlated with the FVC, OC, and reaction temperature, while CO2 has no impact on the catalytic reaction characteristics. Finally, a kinetic equation for the developed catalyst is summarized based on the experimental data, providing a fundamental equation for simulating research on the catalytic reactor and the oxygen-consuming inerting system.
