ADTO # 80 - October 1, 1999
QuestChats require pre-registration. Unless otherwise noted, registration is at: http://quest.arc.nasa.gov/aero/chats/#chatting Join us for a special series of chats focusing on the HSCT! The passenger jet of the future is taking shape! NASA and a team of U.S. aerospace companies have developed a concept for a next-generation supersonic passenger jet -- the High Speed Civil Transport (HSCT). The HSCT would fly 300 passengers at more than 1,500 miles per hour - more than twice the speed of sound! Technology to make the HSCT possible is being developed as part of NASA's High-Speed Research (HSR) program, which began in 1990. The HSCT is expected to cross the Pacific or Atlantic in less than half the time of modern subsonic jets. The HSCT is expected to make its debut in 2015. More about the High Speed Civil Transport at http://quest.arc.nasa.gov/aero/events/hsct.html Tuesday, October 5, 1999, 10 AM Pacific Daylight Time: Linda Bangert, aerospace technologist Linda tests airplane models in wind tunnels and simulates jet engine exhaust using high pressure air. The results of these tests help her understand how propulsion may affect certain aircraft designs. In addition to supporting testing for military aircraft, Linda also tests designs for future supersonic passenger airlines during take off and landing speeds (about 180 miles per hour).

SMART FILTERS WANTED
NASA's Quest Project currently offers question-and-answer services in four areas: Mars and Martian exploration, aeronautics and aerodynamics, human spaceflight (space shuttle and space station), and Saturn/Cassini. These q&a services are made possible by two groups of people: NASA experts who answer questions and volunteer smart filters who process answers and make the system work. Our question-and-answer manager, Chris Tanski, is establishing a pool of people who wish to serve as volunteer smart filters for one of these projects. Currently, there is a minimal need for new folks to serve as smart filters however this need changes over time and new folks are added all the time. The smart filter's job is to take incoming questions from students and, using web-based software and lots of instructions, get answers using a variety of methods. There's lots of support along the way and the job is very satisfying. There are two minimum requirements for being a volunteer smart filter: 1-You need to be able to spend at least 30 minutes every other day processing questions (sometimes more, usually less). This is a very important requirement, so please don't reply unless you know you have the time. 2-You need to be able to read and follow detailed and picky instructions. If you are interested in being added to the waiting list and meet the above requirements, send email to Chris Tanski. If you have a specific area from the above four that you'd like to work for, indicate that otherwise he'll add you to the general waiting list. Folks on this list are usually called up to be an active smart filter within a month or two. Thanks for your support.
[Editor's Note: Linda Bangert is usually found on the Women of NASA website. Due to her involvement in the TCA5 test of the High Speed Civil Transport, she joined Aerospace Team in order to help cover this test. Read her profile at http://quest.arc.nasa.gov/women/bios/lsb.html ]
NASA CENTERS WORK TOGETHER
By Linda Bangert
August 19, 1999 I am the Level III Manager for the High Lift element of the High Speed Research (HSR) Program at NASA Langley Research Center in Virginia. Most of my involvement with this test has had to do with model procurement. As HSR winds down the budget gets cut, and the Boeing contract, which provides a lot of the test support, gets cut back so that the NASA people are having to fill in. That's why I am here at Ames. To procure a model the most important thing is to understand what it is you want. That seems straightforward, but you really have to think about it and put it into words it is not. To write a statement of work that you can understand and that the contractor can bid on with minimal chance of misinterpretation is not trivial. My high school English skills pay off here. It's very important for an engineer to speak and write clearly so that other people understand what he is trying to do. I almost never have all the information I need when I begin the procurement process. I have to take a best guess. If I know that more information is going to be forthcoming I have to write the statement of work so that it tells when the information will be available. If information comes up which changes the statement of work this will cost more money. Part of what makes this test interesting is that the model has pieces that were built by four different model shops. This makes life really complicated. We have four sets of drawings, some that interface with others and some that don't interface with others. Some of the parts that are being tested here have been tested before and other parts are new. We need to be careful that we have sorted through the parts to make sure that we have all the parts we need and have left behind or put away the parts we don't need so no one gets confused. This model is very modular. It was built that way on purpose, but because of that it has got a lot of pieces. Throughout this program the main fuselage and inboard wing have stayed the same, and we have added leading and trailing edge flaps, changed the tail, the canard, different outboard wing panels, and more. Mina Cappuccio is the main focal here at NASA Ames Research Center. Normally there is a whole cadre of Boeing support people that look at the data, compare it with other tests, compare it with Computational Fluid Dynamic predictions, and fine tooth comb it for accuracy to make sure all the corrections were applied accurately. Since they are not here I am trying to help. I am plotting up some of the data, and am working with some of the Boeing people who are still involved, but back at Seattle I've been phoning and emailing back and forth to make sure we understand the test plan. I have enjoyed my visit to California. People here think it's hot long before we start complaining back east. I've enjoyed the cool weather, and I did a little sightseeing. This is the end of my second week, and I am going home tomorrow. I was ready to go home sooner because my three-year-old girl said, "Mommy, how many days until you come home?" on the phone the other day.
