This book was released on 1986 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: A basic consideration in designing an on-board inert gas generator system (OBIGGS) is to manage the evolution of dissolved oxygen in the fuel such that an inert ullage is maintained. Fuel scrubbing, in which an inert gas is bubbled through the fuel, is the common method of removing dissolved oxygen. Analytical modeling of the scrub gas requirements for fuel scrubbing required experimental data for validation. Tests were conducted to determine if a model based on the ideal gas law, published solubility coefficients, and partial pressure relationships was valid. The excellent agreement between calculated results and test data verified that such a model is valid. Keywords: Fuel scrubbing; Oxygen evolution; Fuel tank inerting; On-board inert gas generator systems; Dissolved gases; Engine fires; Fuel fires.

This book was released on 1986 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary performance of on-board inert gas generator systems (OBIGGS) in laboratory and simulated flight tests indicated these systems were suitable for aircraft implementation. Accordingly, preliminary design studies were made to determine the requirements for aircraft OBIGGS installations and to compare the OBIGGS with other fire protection systems. This report presents a technique for establishing the inert gas required for the design mission and discusses OBIGGS installations on a C-5B and an ATF airplane. Both permeable membrane (PM) and molecular sieve (MS) OBIGGS were considered for both airplanes. When all factors were considered the performance and penalties of the PM and MS OBIGGS on these airplanes was comparable. When compared with other fire protection systems, the OBIGGS had significant weight advantages over foam systems and significant cost and logistics advantage over Halon and liquid nitrogen systems.

Download or read book Analysis of On Board Oxygen and Nitrogen Generation Systems for Surface Vessels written by Zsolt Golenko and published by . This book was released on 1983 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most Navy surface vessels are equipped with cryogenic (LOX and LN) storage-evaporator gas supply systems to produce oxygen and nitrogen for life support, flight service, and other system applications. Increased mobility and independence of land-base logistic support requires new, on-board O2 and N2 generation systems, to be installed on existing and future Navy ships. This study summarizes existing industrial candidate systems, and overviews some new processes under development. Analysis was conducted on gaseous oxygen and nitrogen generation systems of the most likely candidates, and particular attention was focused on molecular sieve gas separators. Next, the report concentrates on engineering design guidelines for constructions of on-board gas generators of confined scales. Safety, maintenance, and standard (industrial and MIL) requirements are summarized to help construct, test, and evaluate a scaled prototype on-board O2/N2 generation system. The study identified two types of presently available industrial gas generation systems suitable for confined on-board applications. However, significant modifications and development are necessary to meet filtration, protection and stress-prevention requirements.

Book excerpt: There have been an increasing number of hypoxia-type incidents, especially in the F-22 Raptor aircraft, that may be related to on-board oxygen generating systems (OBOGS). This report details recommendations made by the USAF Scientific Advisory Board's Aircraft Oxygen Generation (AOG) Quicklook Study to help mitigate this safety problem. The AOG Study Panel received a large number of briefings and perspectives on various aircraft OBOGS standards and designs in general; the F-22 and F-22 OBOGS in particular, pilot physiological performance under various conditions, and many other related issues, from within and outside the United States Government. The Study Panel evaluated the current F-22 oxygen system, OBOGS and life support systems in general (including contaminants that could affect OBOGS operation), and human responses to high altitude rapid cabin altitude changes/rapid decompression environment with less than 90% oxygen. It also assisted with: F-22 return-to-fly criteria as requested, evaluation of Air Standards, review and validation of performance-based acquisition programs and associated risk analysis protocols, and with reviewing and revalidating aircrew flight equipment affiliated with OBOGS-equipped aircraft.

Available in PDF, EPUB and Kindle. Book excerpt: The information provided in SAE AIR825/6 applies to On Board Oxygen Generating Systems (OBOGS) - Molecular Sieve, that utilize the ability of molecular sieve materials by using Pressure Swing Adsorption Process (PSA) to separate and concentrate oxygen in the product gas from the surrounding air, respectively air provided by any compressor or by the aircraft engine (so called: Bleed Air), and to provide this oxygen enriched air or product gas as supplemental oxygen for breathing gas supply of crew and passengers onboard aircraft. The distribution system and the provided oxygen concentration have to fulfill the respective FAA/JAA regulations.Equipment using this technology to provide supplemental oxygen for breathing gas supply of crew and passengers onboard aircraft, the suitable breathing gas oxygen partial pressure or oxygen concentration requirements are specified in AIR825/2 and the oxygen purity requirements in AS8010.NOTE: OBOGS has never been certified for commercial aircraft. The FAR/JAR 25 as well as FAR 121/JAR-OPS need to be reviewed and if necessary amended prior to introduction of OBOGS. Alternatively, such certification will likely incorporate various special conditions that address differences in performance between OBOGS and conventional systems.These systems are intended for: athe on-line breathing gas supply to directly account for the normal oxygen usage of crew and passengers in terms of: 1supplemental oxygen for part or all of an emergency descent 2supplemental oxygen for first aid 3therapeutic oxygen bthe replenishment of the aircraft gaseous oxygen system storage cylinders to account for the normal oxygen usage of crew and passengers and system leakage ca combination of the above.The possible applicability and benefit of incorporation of OBOGS-Molecular Sieve into non-military aircraft is being considered by the representatives of Civil Aviation. The intended aim of AIR825/6 is to provide a fundamental description of the function of existing OBOGS-Molecular-Sieve systems with a related reference to the type of oxygen standards which would merit a review. AIR825/6 has been reaffirmed to comply with the SAE five-year review policy.
Download or read book The F 16 Onboard Oxygen Generating System Performance Evaluation and Man Rating written by and published by . This book was released on 1983 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: An onboard oxygen generating system (OBOGS) has been developed by Clifton Precision, according to U.S. Air Force School of Aerospace Medicine (USAFSAM) specifications, for a flight test demonstration in the F-16A aircraft. Prior to actual flight test, the system was certified at the USAFSAM as described in this report. Laboratory testing consisted of manned and unmanned tests at ground level, at altitude, during rapid decompressions, and during acceleration loading. System hardware consisted of a molecular sieve concentrator, breathing-gas regulator, selector valve, product gas composition controller, backup oxygen supply (BOS), and a breathing mask. These components replace current liquid oxygen (lox) components and eliminate the need to service lox converters, resulting in faster aircraft turnaround time, increased safety, and decreased cost. Laboratory test results indicated that the F-16A OBOGS was adequate for flight test and that the breathing-gas composition was physiologically capable of preventing hypoxia and reducing the occurrence of atelectasis. Furthermore, the OBOGS provided considerably less breathing resistance than current lox systems. The concentrator and BOS provided the ability and redundancy to protect the pilot throughout the operational envelope of the F-16A. (Author).
