T-tail VS Boom Tail

[CyanidE]

السلام عليكم و رحمة الله
اخواني الله لا هانكم بغيت منكم تفيدوني بمعلومات عن T-tail VS Boom Tail
لانه عندي بروجكت و قاعد اجمع معلومات عن هالموضوع
و السموحه ..
ادري انه اول موضوع لي و الله كتب انه يكون طلب .. بس السموحه و ان شاء الله يكون لنا دور فعال اكبر من هذا في المستقبل ..
مع السلامه

The tail plane surfaces are kept well out of the airflow behind the wing, giving smoother flow, more predictable design characteristics, and better pitch control. This is especially important for planes operating at low speed, where clean airflow is required for control. deHavilland Canada's line of larger STOL aircraft all use this arrangement for this reason.

The effective distance between wing and tailplane can be increased without a significant increase in the weight of the aircraft. The distance between the two planes gives the "leverage" by which the tailplane can control the aircraft's pitch attitude - with a greater distance, smaller, lighter tailplanes and elevators can be used.

The tail surfaces are mounted well out of the way of the rear fuselage, permitting this site to be used for the aircraft's engines. This is why the T-tail arrangement is also commonly found on airliners with rear-mounted engines. The Douglas DC-9, Boeing 727, Vickers VC-10, Hawker Siddeley Trident, BAC 1-11, Tu-134, Tu-154, Il-62 all used the T-tail for this reason.

The horizontal stabilizer is kept farther away from the ground, which helps reduce damage to it by objects on the ground when taking off or landing. This is not normally a large concern for full scale ('real') planes, but for model airplanes it can be, especially if the plane has no landing gear. This benefit is also shared by V-tails and cruciform tails

Twin-boom aircraft have their tail planes (http://en.wikipedia.org/wiki/Tailplane) and vertical stabilizers (http://en.wikipedia.org/wiki/Vertical_stabilizer) mounted on the tail of either two fuselages (http://en.wikipedia.org/wiki/Fuselage) or on two booms fixed to either both sides of the single fuselage, the wings (http://en.wikipedia.org/wiki/Wing) or the engine (http://en.wikipedia.org/wiki/Engine)nacelles (http://en.wikipedia.org/wiki/Nacelle).
The reason for this design choice may be:
To be able to place a cargo door in the back of the aircraft (examples include the C-82 Packet (http://en.wikipedia.org/wiki/C-82_Packet) and C-119 Flying Boxcar (http://en.wikipedia.org/wiki/C-119_Flying_Boxcar))
To construct propeller (http://en.wikipedia.org/wiki/Propeller) aircraft in pusher configuration (http://en.wikipedia.org/wiki/Pusher_configuration) or jet aircraft (http://en.wikipedia.org/wiki/Jet_aircraft) with the engine mounted directly to the aft of the fuselage (Bell XP-52 (http://en.wikipedia.org/wiki/Bell_XP-52), De Havilland Vampire (http://en.wikipedia.org/wiki/De_Havilland_Vampire))
For unobstructed field of view or field of fire to the rear (Focke-Wulf Fw 189 (http://en.wikipedia.org/wiki/Focke-Wulf_Fw_189))
Twin aircraft, constructed by putting two copies of an existing traditional aircraft side-by-side, (P-82 Twin Mustang (http://en.wikipedia.org/wiki/P-82_Twin_Mustang), Messerschmitt Me 609 (http://en.wikipedia.org/wiki/Messerschmitt_Me_609))
To accommodate early inline engines and their lengthy turbochargers in the most aerodynamically efficient/practical planform (P-38 Lightning (http://en.wikipedia.org/wiki/P-38_Lightning)) & (P-61 Black Widow (http://en.wikipedia.org/wiki/P-61_Black_Widow))
To increase an aircraft structure's rigidity, strength, and internal volume (Rutan Voyager (http://en.wikipedia.org/wiki/Rutan_Voyager), Scaled Composites (http://en.wikipedia.org/wiki/Scaled_Composites) Grizzly, Virgin Atlantic GlobalFlyer (http://en.wikipedia.org/wiki/Virgin_Atlantic_GlobalFlyer), Transavia PL-12 Airtruk (http://en.wikipedia.org/wiki/Transavia_PL-12_Airtruk))
To provide for room to carry external cargo, such as Scaled Composites WhiteKnightTwo (http://en.wikipedia.org/wiki/Scaled_Composites_WhiteKnightTwo). Burt Rutan refers to this design concept as "open architecture".
