Feb 20, 2018 · Static longitudinal stability criteria determine the area of the empennage - upon a disturbance in Angle of Attack, the total aircraft must generate a moment that counteracts the disturbance. Usually, wings and fuselage contribute negative stability, and the tailplane must be sized such that the stabilising moment compensates for this in all ...

Aug 1, 2015 · The empennage height is the distance from the ground to the top of the tailfin. It determines the minimum clearance the aircraft needs to taxi under an obstruction. Share

Oct 2, 2023 · The V-tail was a trend in glider design between the late Fifties and the early Sixties. High-performance gliders like the HKS-1, the Arlington Sisu 1A $^*$, the SB-5, the Standard Austria or the Schempp-Hirth SHK had them, as well as the aerobatic H-101 Salto.

How is the ATR 42/72 empennage considered? Is it a T-Tail or a cruciform tail? From the image the elevators are placed quite high on the tail that they can be considered as a T-Tail but is it so?

Dec 25, 2017 · How is the height of the vertical and span of the horizontal stabilizers determined for different turbofan aircraft like the Airbus A380 and the Boeing 747-8? What are the maximum forces (in kilog...

Jun 28, 2019 · The critical aspect for Vertical stab height is its rolling torque and how it affects the balance of total side slip forces on the aircraft, including wing, fuselage, landing gear, engine mounts.

The recent Oct 2021 YouTube video (The Insane Engineering of the 787 by Real Engineering) in the related question remarks: [...] tiny doors whose purpose are a mystery to me with little to no

Mar 16, 2017 · $\begingroup$ Looking at the picture, I see that the forward portion of the empennage fairing does not line up with what appears to be a joint in the skin structure. However, the joint may be off-center compared to the rivet placement. Looking at the empennage in person may reveal it to be off centerline, but this is not clear to me from the ...

Jul 20, 2021 · I'm specifically interested in these models: A319, B737-700, A220, E195-E2. You could call these conventional airliners, so I suppose the question is if these "conventional" planes have o...

May 9, 2016 · The S-70 Black Hawk has some kind of movable surfaces on its tail, look: Source: Airliners.net They look like "elevators" on airplanes. Does anybody know what are these things for?
