Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen fuel tank inerting has been shown to be an effective means of providing aircraft explosion prevention by reducing the O2 concentration below the lower limit for fuel vapor ignition. A program for the feasibility study and laboratory demonstration of fuel tank inerting by nitrogen generation was conducted. Typical system requirements have been defined using the McDonnell Douglas DC-10 as a transport aircraft representative of potential applications. The study concluded that both the catalytic combustion of air with turbine engine fuels and air separation by hollow fiber permeable membranes are viable candidates. A preliminary design for a DC-10 system based on hollow fiber permeable membranes has been established. Data from laboratory testing demonstrate system operation as an inert gas generator and good compliance with performance predictions.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An airplane fuel tank inerting system provides an inert atmosphere in a fuel tank to minimize explosive ignition of fuel vapor.This SAE Aerospace Information Report (AIR) deals with the three methods of fuel tank inerting systems currently used in operational aircraft: (1) on-board inert gas generation systems (OBIGGS), (2) liquid/gaseous nitrogen systems, and (3) halon systems. The OBIGGS and nitrogen systems generally are designed to provide full-time fuel tank fire protection; the halon systems generally are designed to provide only on-demand or combat-specific protection.This document also addresses other design considerations that affect fuel tank flammability such as fuel tank pressure and other methods for reducing fuel tank flammability.This AIR does not treat the subject of explosion suppression foam (ESF) that has been used for fuel tank explosion protection on some military aircraft. ESF is also available for retrofit for commercial airplanes. The primary disadvantages of foam are weight, reduction of usable fuel, and the added maintenance complexity when the foam must be removed for tank maintenance or inspection. AIR4170 is an excellent reference for the use of ESF for fuel tank explosion protection.Note that across the military and commercial aviation industry, different terminology has been used regarding fuel tank inerting. In military applications, the system is referred to as on-board inert gas generation system (OBIGGS). Regulatory agencies use the term flammability reduction means (FRM). OEMs in commercial applications use several terms: fuel tank inerting system (FTIS), flammability reduction system (FRS), inert gas system (IGS) and nitrogen generation system (NGS). The document is being revised to update the document and to prevent duplication with ARP6078. The document updates include changing the title, the scope, and the rationale of the document.

ESF is a totally passive, full-time protection system with multiple and simultaneous hit capability up to 23 mm. The primary disadvantages of foam are weight, reduction of usable fuel, and the added maintenance complexity when the foam must be removed for tank maintenance or inspection. AIR4170A is an excellent reference for the use of ESF for fuel tank explosion protection [1]. Aerospace Information Report (AIR) 1903 provides technical information and references for developing an airplane fuel tank inerting system.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Aerospace Recommended Practices of this document are intended for nitrogen-based Flammability Reduction Means (FRM) implemented on transport category, turbine powered airplanes. The recommended practices herein, therefore, relate only to the transport category aircraft, and focus specifically on contemporary inerting systems equipment. Such systems are referred to a Fuel Tank Inerting Systems (FTIS) in this document. This document does not cover the following: Military aircraft applications Air separation technologies other than hollow fiber membrane (HFM) and pressure swing adsorption (PSA) Inerting of conventional unheated wing tanks or aircraft dry bays Expected future technology solutions for the generation of inert gas.The advice contained in this document is aimed towards providing aircraft manufacturers with guidance on the key issues associated with contemporary aircraft fuel tank inerting systems to supplement the guidance in FAA Advisory Circular AC 25.981-2. This document also provides system and component designers and manufacturers with advice on what aspects must be evaluated and addressed when designing a safe, low risk solution for transport aircraft fuel tank Flammability Reduction Means. As such, the information herein is intended as a guide for some system design aspects, but primarily identifies the issues which must be addressed in designing an inerting system for fuel tank flammability reduction. This document provides recommended practices for developing a non-aircraft specific commercially certifiable nitrogen based Flammability Reduction Means (FRM) including the applicable design considerations supporting Title 14 Code of Federal Regulations part 25, Appendix M, for Transport Category Airplanes" (Reference 14 CFR 25.981).

Book excerpt: The program successfully demonstrated the feasibility of using permeable-membrane, hollow fibers to generate an inert gas to protect the aircraft fuel system against fire and explosion induced by natural sources or combat. The initial contract requirements included a flight demonstration of an onboard inert gas generator system (OBIGGS) using an Air Force KC-135A aircraft. The design of an inert gas generator (IGG) is highly dependent on the flight profile, engine characteristics, and fuel system designs. Mission analysis translated these parameters into an 8 lb/min inert gas generator that produced less than 9-percent oxygen. A life-cycle cost (LCC) analysis compared the state- of-the-art liquid nitrogen (LN2) system utilized on the C-5A aircraft against the IGG system designed for the KC-135A. Results showed the IGG system reduced LCC by 60 percent. Further, the IGG system eliminates the logistic constraints imposed by the use of LN2, thus allowing unrestricted deployment of the aircraft. A second LCC analysis was conducted in which the permeable-membrane system was compared against the blue foam design used on the C-130 aircraft. The LCC analysis shows great advantage for OBIGGS over blue foam. The externally pressurized polymethylene hollow fiber bundles are expected to exceed the 20- year life expectancy of the aircraft.
