Book excerpt: This report presents the results of a study, funded by the Federal Aviation Administration (FAA), of helicopter Crash-Resistant Fuel Systems (CRFS). It covers the historical efforts that led to the current state of the art in military helicopter fuel systems and the more recent modifications to civil certification standards in Title 14 Code of Federal Regulations (CFR) Part 27 (Normal Category Rotorcraft) and Part 29 (Transport Category Rotorcraft). It describes the basic research, testing, field investigations, and production efforts that have led to the highly successful CRFS, that have saved many lives and have reduced the costs of accidents. While the hardware and fabrics are available today to create the CRFS, the adequacy of the integration of these items into existing and new civil fuel system designs cannot be assessed because of the lack of cuiTent field investigation data on civil helicopter crashes. This report reviews this problem, including the forms used for reporting and the current level of available data, which is essentially nonexistent. Training of field investigators in specific crashworthiness technology is of great importance, as well as the need for trained engineers in the design and certification process. A discussion of the civil and military crash environments is provided to give a background for the discussion of the need for reevaluation of the rationale used in establishing the current civil regulatory standards. The value of full-scale crash testing during the early development of the military CRFS is reviewed. The lack of any planned tests for the CRFS in current civil helicopters is an area of concern. A section of the study discusses the individual components of a CRFS, with guidance on the application of each item to the overall system design. This report provides guidance to designers looking for information about CRFS design problems and analytical tools for use in product improvements.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a study, funded by the Federal Aviation Administration (FAA), of transport airplane crash-resistant fuel system (CRFS). The report covers the historical studies related to aircraft crash fires and fuel containment concepts undertaken by the FAA, NASA, and the U.S. Army, which ultimately led to the current state of the art in CRFS technology. It describes the basic research, testing, field investigations and production efforts which have led to the highly successful military CRFS, which has saved many lives and reduced costs of accidents. Current CRFS technology used in transport category airplanes is defined and compared to the available state-of-the-art technology. The report provides information to the FAA and other government organizations which can help them plan their efforts to improve the state of crash fire protection in the transport airplane fleet. The report provides guidance to designers looking for information about CRFS design problems, analysis tools to use for product improvement, and a summary of current and proposed regulations for transport category airplane fuel systems.

This book was released on 1971 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of the program was to obtain empirical data to evaluate the effectiveness of the UH-1D/H helicopter crash-resistant fuel system when subjected to a severe but survivable crash environment. These data would reveal any specific weaknesses which still remain in the system that would cause a serious fire hazard. Since the performance of the various system components is the key to the effectiveness of the system, the evaluation of these components was the secondary objective of the program.

This book was released on 1969 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A crash test of a UH-1A helicopter was conducted to determine the effectiveness of a complete crash-resistant fuel, oil, and electrical system under severe accident conditions. The system included: special crash-resistant fuel and oil tanks, flexible fuel and oil lines that replaced many rigid lines, and self-sealing breakaway valves and fluid-line disconnects at strategic locations. The aircraft was flown by remote control during the crash test, in which all fuel tanks were filled with empulsified JP-4 and the engine was operating on emulsified JP-4. (Author).

This book was released on 1997-09-18 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reduction of the fire hazard of fuel is critical to improving survivability in impact-survivable aircraft accidents. Despite current fire prevention and mitigation approaches, fuel flammability can overwhelm post-crash fire scenarios. The Workshop on Aviation Fuels with Improved Fire Safety was held November 19-20, 1996 to review the current state of development, technological needs, and promising technology for the future development of aviation fuels that are most resistant to ignition during a crash. This book contains a summary of workshop discussions and 11 presented papers in the areas of fuel and additive technologies, aircraft fuel system requirements, and the characterization of fuel fires.

This book was released on 1965 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: A crash-resistant fuel system, utilizing high-strength bladder fuel cells, breakaway fittings, crash-load-actuated shut-off valves, and fiber glass protective liners, was designed and installed in the center section of a DC-7 aircraft wing. The wing was mounted on a wheeled dolly. A jet-propelled car was used to accelerate the wing and dolly to predetermined velocities prior to engaging a decelerator. The decelerator, especially designed for this project, imposed controlled decelerations on the wing ranging from 2 g's to 21 g's (28-g fuel equivalent). There were no failures in either standard or crash-resistant fuel (CRF) system fuel cells and no inadvertent valve closures in the CRF system during the tests. Hydraulic loads were nominal and were not additive from one cell to another through interconnections. A final destructive test was conducted wherein the wing, at a velocity of 77 knots, engaged two stationary vertical poles, positioned to shear the wing panels at the outboard nacelles. It was demonstrated that, with a more positive means of triggering shut-off valves, the CRF system has a potential for greater chances of fuel containment, with consequent less fire hazard, in case of survivable crashes. The CRF system, as installed in a DC-7, imposes a penalty of 6.97% fuel volume loss for a range loss of 7.6%, although it results in a weight decrease of about 1200 pounds. (Author).
