Examples of Using TAILPLANE in a Sentence

• A tailplane, also known as a horizontal stabilizer, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes.
• Miles' chief aerodynamicist, Dennis Bancroft, was interviewed many years later in 1997 on his reason for needing an all-moving tailplane in his 1944 design.
• Their stability is achieved by a combination of design and trim, - the relationship between centre of gravity, wing and tailplane incidence and rudder setting.
• The investigation led to the discovery of what became known as deep stall or superstall, a phenomenon caused by reduced airflow to the tailplane caused by the combined blanking effects of the wing and the aft-mounted engine nacelles at high angles of attack, which prevents recovery of normal (nose-down) flight.
• A T-tail is an empennage configuration in which the tailplane of an aircraft is mounted to the top of the fin.
• "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a downward angle from horizontal of the wings or tailplane of a fixed-wing aircraft.
• Early work on the project included tailless aircraft designs, which would have used wing-tip vertical surfaces instead; however as the proposal matured, a high-mounted, full tailplane was adopted instead.
• The 170B model also included a new tailplane, a revised tailwheel bracket, and other refinements over the 170 and 170A.
• In contrast, the tailplane, which was positioned forward of the fin, was braced from beneath via struts.
• During World War II, the company built DFS Habicht training gliders, as well as tailplane assemblies for the Messerschmitt Bf 109.
• While the winds and empennage control surfaces were also clad in fabric, metal plating covered the tailplane and fin.
• A quadrant-shaped rather than rectangular rear window, tailwheel replacing skid, revision of shape of empennage and removal of tailplane upper bracing.
• The ply covered tailplane is mounted on a small step above the fuselage; together with the fabric covered elevators the horizontal tail is trapezoidal in plan with rounded tips.
• On 28 June 1982, however, the tailplane detached from an Aeroflot Yak-42 in flight owing to a failure of the actuator screw jack, causing the aircraft to fatally crash near Mazyr.
• Other advanced features included control surface trim tabs, an autopilot and de-icing boots for the wings and tailplane.
• Both the wings and tailplane are swept, with the folding wings having a sweepback of about 45 degrees, while the aircraft is powered by a non-afterburning SNECMA Atar 8K-50 turbojet with a rating of 49 kN (11,025 lbf).
• For carrier stowage the wings folded back horizontally at the roots; the small vertical protrusions on the upper wingtips held hooks that attached to the tailplane.
• The Firefly was a low-wing cantilever monoplane, featuring an oval-section metal semi-monocoque fuselage and a conventional tail unit with forward-placed tailplane.
• The XP-87 was a large mid-wing aircraft with four engines paired in underwing pods, with a mid-mounted tailplane and tricycle undercarriage.
• The R-1300 models also used a single horizontal tailplane in place of the early inverted "V" style, and a new hydro-mechanical clutch gave smoother and more rapid rotor acceleration during clutch engagement and allowed the engine to be started and operated at any speed while disengaged from the transmission and rotors.
