Boeing 747-8 Performs, Think before you’re allowed to drive at the maximum speed on a highway and you have to suddenly stop the car.
It’s basically what to do Boeing test pilot Captain Kirk Vining recently had with the new 747-8 Freighter airplane during one of the most dramatic certification tests. But instead of a 4,000-pound (1815 kg) car weighed in the 747-8 at close to £ 1,000,000.
The Boeing 747-8 Intercontinental and 747-8 Freighter are the new, high-capacity 747, the lowest operating costs and best economics of operating large passenger or freighter airplane. Both are to do on the way to their first deliveries later this year after certification.
Boeing 747-8 Performs Ultimate Rejected Takeoff
Capt. Vining rolled the plane out of the beginning of the runway and began the take-off as usual by all four engines at maximum thrust.
In April, a fully-loaded 747-8 Freighter with worn-out brakes attempted an aborted takeoff on a California runway. The rejected takeoff or maximum brake energy test is one of the most dramatic for a new airplane Boeing 747-8.
Just as the Boeing 747-8 plane was about 200 miles per hour (320 kilometers per hour) to go, Capt. Vining hit the brakes. To channel maximum power, the carbon brakes, it was not allowed to use the thrust reversers.
The brakes made by Goodrich, did exactly as they were. In fact, the 747-8 was used as the team had hoped against the target by more than 700 feet (200 meters).
The kinetic energy of a moving airplane was transferred to the brakes in the form of enormous heat, estimated at more than 2,500 degrees Fahrenheit or 1,400 degrees Celsius. As expected, the brakes glowed a bright orange cast as smoke.
Firefighters arrived and were in an emergency act, but called for the aircraft certification requirements, can set up for five minutes alone.
