How are empennage airfoils chosen? - Aviation Stack Exchange 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
Why don’t gliders use swallow tails? - Aviation Stack Exchange 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 are the dimensions of the empennage determined for jetliners? 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
empennage - Does the tailplane see a higher or lower airspeed than the . . . Usually it has to be about 5° higher as the the Wing so the critical Machnumber is higher for the Empennage You dont wanna lose efficiency due to shock waves on the tails (tails have always to work) There are also rules for the thickness and other parameters of the Empennage You can find some more of them here
Does empennage height above the main wing matter [closed] 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
safety - How are further structural failures prevented if an aft . . . Unless there's an explosion or some catastrophic failure of the pressure vessel, escaping cabin pressure by itself cannot pressurize the open empennage Pressurized aircraft also have a safety valve to protect the pressure vessel from structural damage in the event of outflow valve failure
