What does the fuselage do on a plane?
Fuselage, central portion of the body of an airplane, designed to accommodate the crew, passengers, and cargo. It varies greatly in design and size according to the function of the aircraft.
What is on the horizontal stabilizer?
At the rear of the fuselage of most aircraft one finds a horizontal stabilizer and an elevator. The stabilizer is a fixed wing section whose job is to provide stability for the aircraft, to keep it flying straight. The horizontal stabilizer prevents up-and-down, or pitching, motion of the aircraft nose.
What kind of airplane has a trimmable stabilizer?
Trimmable horizontal stabilizers (THS) are found in majority of airliners and large transport aircraft (like C-17 globemaster III, for example). They are usually part of the trimming system of the aircraft, unlike the elevators, which are controlled by conventional pilot inputs (like yoke etc.).
When do you need a moveable stabilizer on an airplane?
But once the wing loading goes up to jet levels, and the wing is fitted with slotted fowler flaps, a moveable stabilizer is unavoidable. Trimmable horizontal stabilizers (THS) are found in majority of airliners and large transport aircraft (like C-17 globemaster III, for example).
How does a trimmable stabilizer work on an elevator?
The stabilizer trim is normally adjusted to compensate for centre of gravity position prior to takeoff to ensure optimum elevator effectiveness. In most cases, a trimmable stabilizer is either manually or electrically controlled and hydraulically actuated.
Why is a stabilator used in supersonic aircraft?
The stabilator or all moving tailplane is entirely different (with no elevators) and is mostly used in supersonic aircraft. It is used mainly to overcome the problem where elevator becomes unusable due to shockwaves produced by tailplane and the problem of Mach tuck.
