The bending loads are the same..but when placed at the top of the tail the vertical structure must be capable of transmitting those loads and could require additional material (stiffening). In an aircraft with wing mounted engines you get a pitch up moment when you apply thrust (but most of the time if you have to increase thrust its because you are on speed and below profil or on speed but below profil). I suppose it is possible to disrupt the flow enough to where the controls are ineffective but not enough that it can still hold the nose pitched up to a stall although it seems like long shot and/or a poor design. Human Error in Aviation and Legal Process, Stabilised Approach Awareness Toolkit for ATC, Flight Deck Procedures (A Guide for Controllers). A conventional tail tends to drag the stabilizer through the grass on landing, hooking tips and causing massive bending loads on the tailboom. The airplane lands in typical crosswind with no issues. This is because the conventional-tail aircraft has the downwash from the propeller pushing down on the tail to assist in raising the nose. On light airplanes, the primary reason that T-tails were used was aesthetics. Either way it makes more sense to have a pitch up tendency when appying more thrust. Most aircraft feature empennage incorporating vertical and horizontal stabilizing surfaces which stabilize the flight dynamics of pitch and yaw as well as housing control surfaces. 10. The most noticeable difference is that V tail aircraft are much more sensitive to being loaded tail-heavy. My thoughts on 159 hours in rented T-tail Turbo Arrows One nice feature on my Sky Arrow is that the position of the CG means that if you lower the tail to the ground it stays there: I think the OP was asking about 'real' planes. BillTIZ, Oct 4, 2015 #4 frfly172 Touchdown! T-tails may be used to increase clearance at the rear of a cargo aircraft such as the Boeing C-17 Globemaster, to provide extra clearance when loading the aircraft. Disadvantages: Very messy loading and structural design. I guess I'd like to know what makes a T-tail advantageous as opposed to a conventional tail. conventional tailswing verses zero tailswing | Lawn Care Forum With heavy attachments or loads the zero swing is likely to pitch more than a conventional machine. Used Aircraft Guide: Piper Arrow - AVweb This is one reason you'll find T-tail aircraft equipped with elevator down-springs or stick pushers for stall recovery. In comparison with conventional-tail aircraft, the elevator on a T-tail aircraft must be moved a greater distance to raise the nose a given amount when traveling at slow speeds. T-tails pros / cons | Pilots of America The tail of an airplane won't drag behind it if the airplane uses tricycle landing gear. Press J to jump to the feed. T-tails keep the stabilizers out of the engine wake, and give better pitch control. The main hazard with this design is the possibility of entering aDeep Stall. The Boeing 737 was initially planned with rear-mounted engines, like the Sud-Aviation Caravelle, which it was meant to replace. Why would a stretch variant need a larger horizontal stabilizer? Let me repeat that, just in case you missed it . The horizontal stabilizer acts like a winglet, reducing induced drag of the rudder. This is because there is generally less surface area needed for a V-Tail (you have two surfaces cutting through the air, not three). The t-tail is a popular design in aircraft with aft fuselage mounted engines (e.g. Why do trijets (3 rear engines) usually have a T-tail instead of a normal tail? However, the downwash induced by the main wing on the flow is taken into account (for the cruise conditions) in the design of the tail in order to reduce some negative aspects of the interaction between the main wing and the tail. There can also be some slight negatives in terms of efficiently generating pure pitch or yaw moments without also generating unwanted roll moments. Easy to recover from spin: It is easy to recover from a spin with this type of design because the elevator is located above the rudder. Thanks for the photo of the model. With the rudder, a right rudder input in the V-tail will lower the right ruddervator and raise the left one. When the vertical tail is swept, the horizontal tail can be made smaller because it is further rearwards and therefore has a greater lever arm. Every type from fighters to helicopters from air forces around the globe, Classic Airliners 2.2.3: Empennage - Engineering LibreTexts The cruciform tail, in which the horizontal stabilizers are placed midway up the vertical stabilizer, giving the appearance of a cross when viewed from the front. I would be keeping that in mind if I ever had an emergency in the plane. In fact, I was under the impression that a major disadvantage of a T-tail was that the wash during a stall could envelope the tail and remove the authority needed to correct the situation. My code is GPL licensed, can I issue a license to have my code be distributed in a specific MIT licensed project? Tell us in the comments below. Cruise speeds range from 130 (180-HP) to 143 knots (normally aspirated 200-HP T-tail) and as high as 170 knots for a turbocharged version flown in the teens. Get Boldmethod flying tips and videos direct to your inbox. Why do big modern airplanes not use a T-tail configuration for the horizontal stabilizer? Advantages Of A T-tail Vs. A Conventional Tail, RE: Advantages Of A T-tail Vs. A Conventional Tail. If "all flying rudders" for LSA aircraft need up to 40% less area, what about "all flying elevators (stabilators)"? Are there specific advantages to a T-Tail vs. a conventional tail? This is because the conventional-tail aircraft has the downwash from the propeller pushing down on the tail to assist in raising the nose. A T-tail produces a strong nose-down pitching moment in sideslip. There are several things to consider in a T-tail design. some extra effort in hinging and hooking up. 5. Pros: 1. This is because the V tail has projected area in both directions. [citation needed], The T-tail configuration can also cause maintenance problems.

Kingdom Chromista (= Stramenopila or Heterokonta): - Hyphochytriomycota, the "tinsel-tailed water moulds" They regulate aquatic populations of freshwater planktonic algae, chytrids and oomycetes. T-tails have a good glide ratio, and are more efficient on low speed aircraft. Tailplane more difficult to clear snow off and access for maintenance and checking. somewhat susceptible to damage in rough field landings. BeechTalk.com BT - V-Tail versus Conventional Tail When I sell my Archer, I'm buying a lance. This gives them greater authority and consistency over a wider flight regime, but unfortunately also means you will have the authority to worsen a developing stall. Quiz: Can You Answer These 7 IFR Checkride Questions? I too love the look of a V tail, and soon enough ill be trying my first V tail home build! The disadvantages ot the T-tail concept are the mentioned deep stalls, maybe a elevator stall during flare, unfavourable C.G. The T-tail lifts the horizontal tail clear of the wing wake (downwash) and propwash, which make it more efficient and hence allow reducing its size and also allows high performance aerodynamics and excellent glide ratio as the horizontal tail empennage is less affected by wing slipstream. Piper Arrow - Aviation Consumer But, they handle turbulence much better and are very smooth fliers. If OT and PD cost me 25 dollars and hour more than standard time, I have to do 50% more devices at trim out per hour to break even. A T-tail is a form of empennage where the horizontal stabilizer is mounted to the top of the fin. T-tails also have a larger cross section. Everything from the Goodyear blimp to the Zeppelin, Night Photos The duct is integrated into the tail boom and is usually made of a fiberglass skin. ). This arrangement is different from the normal design where the tailplane is mounted on the fuselage at the base of the fin.
