What is the dome on top of airplane?
An astrodome is a hemispherical transparent dome that was installed in the cabin roof of an aircraft. Such a dome would allow a trained navigator to perform astronavigation and thereby guide the aircraft at night without the aid of land-based visual references.
What is aircraft dome?
A radome (a portmanteau of radar and dome) is a structural, weatherproof enclosure that protects a radar antenna. When found on fixed-wing aircraft with forward-looking radar, as are commonly used for object or weather detection, the nose cones often additionally serve as radomes.
What is the dome on top of 737?
As Mr Chai noted, the hump is a satellite antenna. The fin on the nacelle has nothing to do with cruise turbulence or fuel efficiency. During cruise flight it is at or near zero angle of attack and produces little, if any, aerodynamic effect other than skin friction drag.
What is the interior of a plane called?
The fuselage or body of the airplane, holds all the pieces together. The pilots sit in the cockpit at the front of the fuselage. Passengers and cargo are carried in the rear of the fuselage.
Why do airplane wings have bumps?
The “dynamic bumps” system proposes a grid of oscillating jets, some that suck air and some that expel air, to create a recirculation pattern with magnitude and frequency that acts to weaken the normal shock wave by creating an oblique wave that acts to reduce aerofoil drag.
What are those bumps on top of the Antonov 225?
According to the Airliners.net forum, they are fairings that cover hardpoints used for attaching outsize loads. Outsize loads that cannot fit into the capacious cabin (including Buran and Energiya components) are carried ‘piggyback’, the load supported on two main attachments above the center section.
What are radomes made out of?
Because they protect sensitive instruments while allowing electronic signals to pass through, nose cones – also known as radomes – must be made from specific materials. These materials often include fiberglass, quartz, honeycomb and foam cores; as well as various chemical resins.
What is an aircraft wing?
wing, in aeronautics, an airfoil that helps lift a heavier-than-air craft. When positioned above the fuselage (high wings), wings provide an unrestricted view below and good lateral stability.
What are plane doors called?
Only the doors where cabin crew enter and exit the aircraft are called aircraft service doors.
What are the things under an airplane wing?
Anti-shock body is the name given by Richard T. Whitcomb to a pod positioned on the upper surface of a wing. Its purpose is to reduce wave drag while travelling at transonic speeds (Mach 0.8–1.0), which includes the typical cruising range of conventional jet airliners.
What are pods under wings?
These ‘pods’ are flap track fairings, sometimes called trailing edge fairings, and their purpose is to cover and reduce drag over the heavy duty mechanisms that extend the flaps of an aircraft wing during high-lift operating regimes.
What is the size of the dome on a plane?
The dome is 30 feet (9.1 meters) in diameter, six feet (1.8 meters) thick, and is held 11 feet (3.33 meters) above the fuselage by two struts. It contains a radar subsystem that permits surveillance from the Earth’s surface up into the stratosphere, over land or water. The radar has a range of more than 250 miles (375.5 kilometers).
What is the name of the plane with the hump on top?
The identical planes, which are based at Offutt Air Force Base in Nebraska, have been in operation since 1980. The noticeable hump on top of the plane is called a “radome” and houses some of the nearly 67 different satellite dishes and antennas.
What is the dome on the E-4B?
The dome is one element in the E-4B’s communication portfolio that gives those aboard the ability to contact ships, submarines, aircraft and landlines anywhere in the world. An E-4B is refueled by a KC-10 tanker during a local mission June 12, 2017.
What is the E-4B Doomsday plane?
The E-4B, or “doomsday plane,” is a highly survivable flying fortress used to transport the secretary of Defense. Designed during the Cold War, the four planes are built to endure the immediate aftermath of a nuclear detonation. “The plane is basically a flying command center,” a Pentagon spokesman tells CNBC aboard the aircraft.
