Aerodynamic Heating and Deceleration During E... 
Dr. Chapman's lecture examines the physics behind spacecraft entry into planetary atmospheres. He explains how scientists determine if a planet has an atmosphere and how scientists can compute deceleration when the atmospheric conditions are unknown. Symbols and equations used for calculations for aerodynamic heating and deceleration are provided. He also explains heat transfer in bodies approaching an atmosphere, deceleration, and the use of ablation in protecting spacecraft from high temperatures during atmospheric entry.

3.5 miles in 10 seconds 
Born in Berkeley, California, Crossfield grew up in California and Washington. He served with the U.S. Navy as a flight instructor and fighter pilot during World War II. From 1946-1950, he worked in the University of Washington's Kirsten Wind Tunnel while earning his bachelor's(1949) and master's degrees(1950) in aeronautical engineering. In 1950, he joined the National Advisory Committee for Aeronautics' High-Speed Flight Station (now the NASA Dryden Flight Research Center) at Edwards Air Force Base, California, as an aeronautical research pilot. In those early days, it was called Muroc Field, reverse spelling of the wealthy California Corum family who donated the land to the Army Air Corps. Crossfield joined the Navy because he could enter flight training two weeks earlier than a date offered by the Army Air Corps.

Crossfield demonstrated his flight test skills on his very first student solo. His instructor was not available on the designated early morning, so Crossfield, on his own, took off and went through maneuvers he had practiced with his instructor, to include spin entry and spin recovery. During the first spin, Crossfield experienced vibrations, banging, and noise in the aircraft that he had never encountere...

Boeing 747-400 
The Boeing 747-400 is the latest version of the Boeing 747 in service. The -400 series is the best selling and the most advanced model of the 747 family. The 747-400 is being replaced by the Boeing 747-8, expected to enter service in 2009.

The 747-400 was announced by Boeing Commercial Airplanes in October 1985. Compared to the 747-300 the 747-400 has 6 ft (1.83 m) wing tip extensions and 6 ft (2 m) winglets, an all-new glass cockpit which dispensed with the need for a flight engineer, tail fuel tanks, revised engines, an all-new interior, revised fuselage/wing fairings and newer in-flight entertainment to the basic design of the -300 series. Like the 747-300, the passenger version of the 747-400 included the stretched upper deck (SUD) as a standard feature. The SUD was almost twice as long as the standard upper deck. It had previously been offered as a retrofit and first appeared on two Japanese 747-100 SR models.[1] While the wingspan was increased, the overall weight of the wings was decreased due to the use of composites and aluminum alloys.

It was rolled out in January 1988 and first flew on April 29, 1988. Certification was received on January 10, 1989 with PW4000 engines, May 18, 1989 with CF6-...

Kettering EE Capstone 
Kettering University Capstone Project

Kettering University (formerly the "General Motors Institute") is a university in Flint, Michigan, offering degrees in engineering, the applied sciences, and management. The campus is located along the scenic Flint River on property that used to be the main manufacturing location for General Motors. It is named after inventor Charles Kettering[1].

The university boasts that the majority of its' seniors are employed or accepted to graduate schools before graduation and that one out of 15 alumni either own their own business or are high-level managers in leading companies (see Notable Alumni). Although the school's undergraduate class is small with approximately 2,400 students[2], it graduates one of the largest mechanical engineering graduating classes in the United States annually and is consistently ranked by US News and World Report as one of the best schools in the country for an undergraduate engineering education without PhD programs.

The history of Kettering University is deeply tied to the development of the American automotive industry. The school was originally founded as The School of Automotive Trades in 1919 by A...

11th International Autonomous Underwater Vehi... 

AUVSI and ONR's 11th International Autonomous Underwater Vehicle Competition, July 29 - August 3, 2008, Space and Naval Warfare Systems Center TRANSDEC Facility, San Diego, California, USA. Co-sponsored by the Office of Naval Research (ONR), the goal of this competition is to advance the development of autonomous underwater vehicles (AUVs) by challenging a new generation of engineers to perform realistic missions in an underwater environment. This event also serves to foster ties between young engineers and the organizations developing AUV technologies.

The Association for Unmanned Vehicle Systems International (AUVSI...
