Book excerpt: The purpose of this technology assessment is to define a multiphase research study program investigating Onboard Inert Gas Generation Systems (OBIGGS) and Onboard Oxygen Generation Systems (OBOGS) that would identify current airplane systems design and certification requirements (Subtask 1); explore state-of-the-art technology (Subtask 2); develop systems specifications (Subtask 3); and develop an initial system design (Subtask 4). If feasible, consideration may be given to the development of a prototype laboratory test system that could potentially be used in commercial transport aircraft (Subtask 5). These systems should be capable of providing inert nitrogen gas for improved fire cargo compartment fire suppression and fuel tank inerting and emergency oxygen for crew and passenger use. Subtask I of this research study, presented herein, defines current production aircraft certification requirements and design objectives necessary to meet mandatory FAA certification requirements and Boeing design and performance specifications. These requirements will be utilized for baseline comparisons for subsequent OBIGGS/OBOGS application evaluations and assessments.

Available in PDF, EPUB and Kindle. Book excerpt: The information provided in 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 airworthiness regulations.Equipment using this technology is 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 14 CFR/CS 25 as well as 14 CFR 121/Commission Regulation (EU) N° 965/2012, amended 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. The revision of this SAE Aerospace Information Report, which is intended to provide comprehensive reference and background information pertaining to molecular sieve on-board oxygen generating systems as part of an overall document set to address oxygen equipment for aircraft, some of the background and safety and reliability and physical effects will be reviewed and adapted to the latest knowledge and applications.

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).

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.

Available in PDF, EPUB and Kindle. Book excerpt: The molecular sieve method of generating an enriched-oxygen breathing gas is one of three candidate on-board oxygen generation (OBOG) systems under joint Navy-Air Force development for application in tactical aircraft. As part of this program, the performance of a nominal 2-man-capacity molecular sieve oxygen generation system (MSOG) was characterized under simulated flight conditions. Data were given on the composition (oxygen, nitrogen, carbon dioxide, and argon) of the MSOG-generated breathing gas as a function of inlet air pressure, altitude, and gas flow rate. The maximum oxygen concentration observed was 95% with the balance argon. Under certain conditions of pressure, altitude, and flow, the argon enrichment factor exceeded that of oxygen giving a maximum argon concentration of 6.4% with the balance oxygen. The performance of the MSOG was discussed in the context of aircraft operating envelopes using both diluter-demand and 100% delivery subsystems.
