This book was released on 2017-10-30 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reproduces two important Air Force reports on the hypoxia problem which plagued the F-22 Raptor fighter plane. Process Roadmap: Determining the Cause of F-22 Unexplained Physiological Incidents - U.S. Air Force - The Air Force Scientific Advisory Board's (AFSAB) Quicklook Study on Aircraft Oxygen Generation Systems (OBOGS) has been completed and released. While this study did not determine the root cause(s) for a disproportionally larger rate of unexplained physiological incidents in the F-22 than other fighter type aircraft in the U.S. inventory, it provided processes and procedures to be used in determining the root cause(s) for those incidents. The AFSAB study was the first tier of four in the Air Forces' deliberate effort to find the cause(s) for the F-22's unexplained physiological incidents. The first tier was initiated in April of 2008 with the first reported F-22 physiological incident. Engineers from the F-22 System Program Office, the prime contractor for the F-22, Lockheed Martin, and its two primary subcontractors responsible for the F-22's Life Support System, Boeing and Honeywell, initiated the Root Cause and Correction Analysis process which worked in collaboration with the Air Force safety investigation process to determine the root cause(s) behind reported incidents. Ultimately, causes were determined for two of the 14 incidents reported between April of 2008 and May of 2011. The remaining twelve cases represented a rate of more than ten times the Air Force average for other aircraft systems. After the tragic loss of pilot Capt Jeff Haney and his F-22 in Alaska in November 2010, the initial mishap investigation suggested that hypoxia, a lack of oxygen available to the pilot, may have been causal to the accident. Ultimately, the Air Force's Accident Investigation Board concluded that Haney failed to recognize and initiate a timely dive recovery due to channelized attention. United States Air Force Scientific Advisory Board Report on Aircraft Oxygen Generation - Many aircraft make use of an on-board oxygen generation system to provide breathing oxygen for the aircrew. Compared to historical experience, there have been an increasing number of hypoxia-like incidents in the F-22 Raptor aircraft, that may be related to their on-board oxygen generating systems (OBOGS) or their installation. The United States Air Force (USAF) Scientific Advisory Board was tasked to conduct a Quicklook Study of system safety issues involving OBOGS to help ensure that the appropriate steps are being taken to enhance flight safety of these aircraft. These included, but were not limited to, evaluating the current F-22 oxygen system, evaluating OBOGS and life support systems in general, investigating contaminants that could have an effect on OBOGS operation, evaluating human responses to high altitude rapid cabin altitude changes/rapid decompression environment with less that 90% oxygen, assisting with F-22 return-to-fly criteria as requested, revalidating and clarifying Air Standards, reviewing and validating implementation of performance-based acquisition programs and associated risk analysis protocols, examining specific hypoxia-like incidents occurring in flight regimes not normally considered likely for hypoxia events, and reviewing and revalidating all aircrew flight equipment affiliated with OBOGS-equipped aircraft. Priority was given to F-22 aircraft; however, other OBOGS-equipped aircraft were also considered.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the development of a laboratory working model of a solid chemical oxygen generating system. A design study was conducted to aid in designing a system which would satisfy program specifications and provide operational flexibility and simplicity, minimal maintenance and safe operation. The system which evolved featured: remote and local control of the system, automatic and manual operation modes, six sodium chlorate candles contained in individual rechargable generators and delivered oxygen compatible with MIL-STD-E-83252 (USAF). Each of the sodium chlorate candles were 1.75 in. dia. by 11.75 in. long and contained 6% Fe fuel. The six generators contained in integral filter for contaminant removal. A regenerable dryer using molecular sieves (Linde 13X) was provided for moisture control. For each of the six generators a mass flowmeter was supplied for monitoring the oxygen generation rate. The generated oxygen was stored in a 500 cu. in. accumulator at less than 500 psig. An ignition control system using 28V DC power was developed which permitted the generator activation sequence to be programmed for automatic operation. An override was included for manual operation. Also, an automatic safety override was designed into the ignition control system which removed generator activation power and indicated when the system pressure exceeded 400 psig.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This report sets forth the findings of a test and evaluation (man rating) of the molecular sieve oxygen generation system developed for the 1B Long Range Combat Aircraft. A series of unmanned and manned tests, covering the range of aircraft operating conditions, were conducted on a duplicate of the aircraft breathing system which was assembled in an environmental chamber. The control variables were cabin and aircraft ambient pressure, inlet air temperature and pressure, cabin temperature, and demand flow; and the dependent variables were oxygen concentration, pressure swings in the mask, and time required for backup oxygen to reach the crew after rapid decompression (RD). Oxygen output met or exceeded specification requirements for all but two test points. Under nominal aircraft operating conditions and the maximum average demand flow of 160 liters per minute (1pm), oxygen concentration fell slightly below specification requirements at 25,000 and 28,000 ft cabin altitude. These discrepancies are not considered significant (i.e., will not compromise crew safety), because the probability is very slight that a demand flow rate as high as 160 1pm will ever occur (tests showed that 6 persons taking moderately heavy, rapid breaths generated 135 1pm average demand at ground level). Furthermore, the oxygen partial pressure, in the worst case, was equivalent to breathing air at only 4,000 ft pressure altitude.

This book was released on 2017-11-14 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the Wartime story of Leo Elwood Phillips (1920-2013), one of 11 brothers and sisters that grew up during the Great Depression on a small farm near the Village Of Palestine in Darke County, Ohio. Raised by his mother Bessie after the death of his father Matthew in 1932 from pneumonia, he worked the family farm until graduating from Palestine High School in 1938. He subsequently moved to 19 South Sixth Street in the small Ohio city of Miamisburg to live with his sister Beulah and work as a paper cutter. On 14 May 1942, Leo enlisted as a Private in the Army Air Corps at Patterson Field in Fairfield (Fairborn), Ohio, “ … For The Duration Of The War Or Other Emergency, Plus Six Months, Subject To The Discretion Of The President Or Otherwise According To The Law ...” On 6 June 1942, Leo started classroom training with 12 students at the Bertram School Of Gases, Independent Engineering Company of O’Fallon, Illinois. It is here he became an oxygen and acetylene plant operator - learning to pass air through a series of units that compressed it, removed carbon dioxide, moisture, oil content, and separated liquid air into nitrogen and oxygen. Then, moving liquid oxygen or nitrogen into expansion chambers and finally, compressing oxygen into high pressure cylinders for military aviation use. He completed formal classroom instruction in O’Fallon on the 10th of July and then performed on-the-job training in the Company’s factory until the 17th of September, 1942. From the 2nd to the 16th of November Leo traveled on the troopship SS Monterey from Staten Island, New York to Casablanca, French Morocco, as part of Operation Torch. Shortly after arrival his unit started generating oxygen and filling oxygen cylinders for use on Army Air Forces aircraft such as the B-17 Flying Fortress, B- 24 Liberator and P-38 Lightning. On 30 November 1942, Leo and a number of men he trained with at O’Fallon were transferred from Headquarters and Headquarters Detachment to the 41st Service Group, within the XII Air Force Service Command - a part of Twelfth (XII) Air Force. On 12 February 1943, Leo and his unit were transferred from Detachment XII Air Force Service Command (AFSC) to the 37th Air Depot Group (ADG). On 24 August they were again transferred, this time from Air Force General Depot #3 to Depot #5 within the 37th ADG, XII AFSC. On 26 September 1943, they were transferred (without travel) from the 37th ADG to Headquarters and Headquarters Squadron, 17th Air Depot Group, as part of their anticipated move to recently liberated southern Italy. By August of 1943, newly promoted Sergeant Phillips was generating and filling aviation oxygen in Tunisia and by December was doing the same in southern Italy. All but four of the next 22 months Leo was stationed in and around Bari and Foggia. By mid-1944, all oxygen plant operators in the Mediterranean Theatre of Operations were now attached to the 15th Air Force Service Command (AFSC) Oxygen Detachment, or one of the many Service Groups part of the 15th Air Force. Leo and his men were part of the Oxygen Detachment. From January through October of 1944, the 15th AFSC Oxygen Detachment and Service Groups stationed in Italy collectively filled 225,119 (standard 220 cubic foot) cylinders. The Oxygen Detachment alone was responsible for filling 109,804 – almost half of the total number of cylinders in the Theatre. On 19 November 1944, Leo was promoted to his highest rank, Staff Sergeant (Temporary), while attached to the 18th Air Depot Group. From December 1944 to March 1945, Phillips was sent stateside to Patterson Field near Dayton, Ohio. During this time Leo reported on the status of oxygen generation and use in the Mediterranean Theatre of Operations. While at the Field he also learned how to operate a moisture collector for testing oxygen. He had furloughs during this period from 22 to 29 December 1944 and 22 January to 5 February 1945. For much of this time Leo stayed on Oxford Avenue in Dayton, thus, was able to spend much of his free time with his mother, brothers and sisters now living nearby. Leaving for home permanently on 26 September 1945, Phillips traveled from Naples to New York on the refitted former Italian cruise liner Vulcania. This diesel-powered ship, on its maiden voyage as an allied troopship, was manned by Italian officers and crew. The ship carried 4,057 Americans, including 3,200 Army officers and enlisted men, 557 members of the WAC and 300 nurses. After arriving at Staten Island on 4 October, every soldier was transported to Camp Kilmer in New Brunswick, New Jersey - the largest processing center for troops heading overseas and returning home from World War II. Next, Leo left for Camp Atterbury, Indiana. After further processing to complete the transition from soldier to civilian, Staff Sergeant Phillips received an Honorable Discharge from the 41st Depot Replacement Squadron located at the Separation Center, on 10 October 1945. Soon after coming back home to Miamisburg Leo married Audrey Constance (Case) Phillips and had two children. Audrey was the sister of one of Leo’s closest friends during the War - Ronald A. Case. Leo worked for Burdett Oxygen Company and retired from the Dayton-headquartered bicycle manufacturer Huffy Corporation after 17 years of faithful service. Leo passed on 4 September 2013, after living a rich life which also included tenure as President of the Moose Lodge in Miamisburg, member of St. George's Episcopal Church, Centerville and the love of family, friends, golf, and traveling.
