|1. Tech Center participates in 2006 Atlantic City Air Show
By Mike Greco and Janet Kinsell
On August 23, the Technical Center participated in the 2006 Atlantic City Air Show.
With an estimated attendance of more than 600,000 fans, the show opened with a rendition of the Star Spangled Banner sung by 13 year-old Galloway resident, Morgan Kirner. The beach crowd rose to their feet and boardwalk strollers stopped on a dime as Morgan’s impressive voice serenaded U.S. Army Corporal Josh Coleman, who parachuted in with the American Flag flowing from his back. “How could anyone NOT be proud to be an American,” exclaimed Marcus Forner from Philadelphia. After a thunderous applause, radio personality Pinky Kravitz announced additional U.S. Army sky jumpers and the first of several flyby aircraft, a USAF KC-135 and F-16 provided by our own Air National Guard 177th Fighter Wing.
The Tech Center’s Flight Program operated two aircraft at the airshow - the Boeing 727 and Bombardier Global 5000 large business jet. John Wiley, Managing Director of the Integrated Engineering Services Group, proudly took the microphone stating, “The Technical Center features a fleet of 7 test aircraft. These “flying laboratories” support the FAA’s research and development flight program. Today you are viewing the Boeing 727, which will soon be retired after over 35 years of service AND its replacement, the advanced Global 5000 large business jet, the “star” of the Center’s fleet. The pilots flying the Boeing 727 are John Geyser, Dan Dellmyer, and flight engineer John Tatham. Lorry Faber and Mark Ehrhart are flying the Global 5000.”
The Tech Center also had an information booth at the air show. Volunteers distributed extensive material about the Tech Center to viewers, who showed a lot of interest in the work of the FAA.
Blue Angels visit the Tech Center
Prior to the event, the Tech Center provided critical support to the world famous U.S. Navy Blue Angels precision flying team in the FAA aircraft hangar and in the ramp area. Center personnel from operations and the flight program provided ramp parking, ground control traffic, a pilot briefing room, communications and operational support for the Blue Angel team, as well as several other aircraft participating in the show.
The Blue Angels team involved consisted of 65 airmen, seven F-18 Hornet fighters and “Fat Albert,” a C-130 support and demonstration airplane. Center employees found the Blue Angels to be professional, courteous, and genuinely appreciative of the support provided. This effort remains a great example of cooperation and professionalism amongst government agencies while supporting an aviation promotional event for the public.
The Blue Angels showed appreciation to Center employees and contractors by handing out numerous posters, stickers and brochures to the many people who made their way over to wave to the team as they departed the FAA ramp. Several media flights also launched from our ramp, including TV’s Anne Marie Green (Channel 3) and Matt O'Donnell (Channel 6), plus actor James Franco, who stars in the upcoming aviation movie "Flyboy’s.” Each took flights in the Blue Angels #7 aircraft; a 2-person plane with built in audio and video equipment that provides 3 different views and an instant DVD of the flight to each passenger upon completion of their flight.
Congratulations to all who were involved in producing and supporting this wonderful event.
2. Fire Safety Aboard Aircraft
By Barbara Harris-Para
Editor’s Note: A little background on the Tech Center’s fire safety group: There are 24 people that do extensive testing, research and development in six devoted facilities and three fully operational aircraft (Boeing 747, 737 and 727). The group is the premier laboratory in the world for aircraft fire safety issues. They can respond quickly to practically any aircraft fire safety concern because of their expertise and in-house testing capabilities. As a unique example, Gus Sarkos spoke of a past situation that required immediate attention during the buildup of armaments and supplies during Desert Shield. Stripped of their seats, civilian airliners were being loaded with weapons and supplies atop plywood sheathing and flown to the Middle East. The Associate Administrator for Regulation and Certification contacted Gus for help after concerns were raised regarding the flammability of the plywood. On the same day as the request, when the staff went out for lunch they purchased treated and non-treated plywood sheets. A series of tests were conducted in the afternoon that demonstrated clearly that the use of treated plywood would provide the necessary safety protection. The results were communicated to AVR-1 who passed on the information to the appropriate authorities, allowing the buildup to continue unimpeded with the knowledge that the fire safety risks were minimal. In addition to a quick note to the Administrator complementing the responsiveness of the fire safety crew, those involved were given a special award for their “outstanding contribution to the FAA mission in support of Operation Desert Shield/Storm”.
Have you ever taken notice of how many rows there are between you and the emergency exits on an aircraft, or listened carefully to the flight attendants’ safety briefing? After speaking with Gus Sarkos, Manager of the William J. Hughes Technical Center’s Fire Safety Branch, and Engineer Steve Summer, I will be listening to them, as well as spreading the word about onboard aircraft fire safety.
Steve Summer has recently completed research here at the Center on the fire safety implications of pre-packaged self–heating meals (MREs) designed for military use. They have been marketed right here in NJ, saying they are safe for use in camping, homes, on the road and possibly in aircraft, but Steve sees a different scenario through tests performed in his laboratory.
Steve’s research began with the basic contents of the packaged meal. The food was fine, but what was the means to accelerate the heating process? Well, it was a combination of saltwater and a magnesium-iron mixture. The chemical reaction between the two generated heat that reached temperatures of up to 215 degrees Fahrenheit, as well as hydrogen gas as an unwelcome by-product. We all remember the Hindenburg, the hydrogen-filled German lighter-than-air ship that came to its demise in Lakehurst, NJ during a very charged atmosphere of thunderstorms with lightning. The known flammability hazards of hydrogen, punctuated by the Hindenburg tragedy, made Steve take notice.
First, he began with one meal and a continuous ignition source. Then he added a few more meals in their test tank. When they ignited there was at least 8 times the amount of hydrogen at that point then when he began.
Steve said that one of the factors he considered is that water accelerates the process. That rules out water for fighting a fire that involves these meals, and if the magnesium starts burning there may be very little that can be done to douse the flames. He pointed out that a major fire occurred on a pallet loaded with MREs, fortunately, before being loaded aboard a navy ship. It is suspected that the elevated hydrogen levels within the packages contributed to the fire intensity.
I asked both Steve and Gus how they determine what they are going to test. Their work is entirely driven by their customer, the Associate Administrator for Aviation Safety, whose organization is basically responsible for aircraft certification and operational safety. An involved prioritization process identifies those customer requirements that will be addressed within the available budget constraints, not just for fire safety, but also for the entire Aircraft Safety R&D program. Some of the R&D activities are cooperative ventures with aircraft manufacturers such as Boeing or Airbus, foreign airworthiness authorities, NASA, other government agencies, etc. Over the past 28 years, the Fire Safety Branch has also supported the National Transportation Safety Board (NTSB) investigation of large transport aircraft fires, which is coordinated by the FAA’s Office of Accident Investigation.
Gus mentioned that much of the premier testing information they produce can be found on their website, at www.fire.tc.faa.gov. The website contains the proceedings of two international working groups, chaired and administered by the Fire Safety Branch, each of which meet three times a year, to provide a forum for cooperation and coordination on fire safety R&D. Planning is also underway on a major triennial international conference on cabin safety, which usually draws 400-500 attendees, which will be held in Atlantic City in the fall of 2007.
Gus feels that the Tech Center has the world’s leading experts on aircraft fire safety. In addition, a well-known professor from the University of Maryland will be doing his sabbatical leave here early next year. He will collaborate with the fire safety folks to study the flammability of epoxy/graphite composites, of the type that will be used for the fuselage and wing structure in the new Boeing 787 aircraft. He will be working side-by-side with folks like Steve, Dick Hill, and Dr. Rich Lyon, just to name a few.
Another important study that was recently completed here at the Tech Center was examining methodologies to protect aircraft from accidental fuel tank explosions using inert gases. Steve was responsible for studying the flammability of fuel tanks and, in particular, determining the concentration of oxygen that would prevent an explosion. Gus mentioned that because Steve’s work had such a critical effect on the design of the inerting system developed here, a well-known professor from Cal Tech was tasked by Boeing with validating his findings. In the end, his work withstood the scrutiny of the professor. Boeing built their own inerting system essentially using the FAA design, and the first system was installed in a Boeing airplane last year.
Gus elaborated on future activities to improve aircraft fire safety. The Fire Safety Branch will continue to work on hidden in-flight fires by developing tougher flammability standards for all materials in hidden areas and by improving firefighting tactics. Work will also continue on structural composite flammability issues. Fire protection against shipment of hazardous materials is a growing concern. They have done work on lithium batteries, which were in the news recently with a nation-wide recall of lap tap batteries. The UPS fire in Philadelphia a few months ago had implications as to the severity of that problem. Next-generation batteries may be fuel cells posing another series of problems in air travel. Halon is the agent used today for fire suppression. It is not being manufactured any longer due to environmental issues, so they are testing replacement agents to make sure they are effective. Work will also continue on long range research on ultra-fire resistant materials. So, the folks who work in the Fire Safety Branch have their hands full with new and better approaches to both old and new problems facing aviation.
