Match. Database: Organized collection of data on people, places, or things Database Management System (DBMS): Specific type of software for creating, storing, organizing, and … As mentioned in Chapter 2, Aircraft Structure, a stabilator is essentially a one-piece horizontal stabilizer that pivots from a central hinge point. [Figure 5-15] By pushing the left pedal, the rudder moves left. Antiservo tabs are incorporated on the trailing edge to decrease sensitivity. [Figure 5-19]. aqueous humor. Terms in this set (21) What is viscosity? Chapter 5 : Aerodynamics of Flight - Weight and Balance. Like all control surfaces at lower airspeeds, the vertical stabilizer/ rudder becomes less effective, and magnifies the control problems associated with adverse yaw. vitre/o. On larger aircraft, it is motor driven. As is true with trailing edge flaps, a small increment of leading edge flaps increases lift to a much greater extent than drag. lens (lentil) phot/o. The most common installation on small aircraft is a single trim tab attached to the trailing edge of the elevator. Movement of any of the three primary flight control surfaces (ailerons, elevator or stabilator, or rudder), changes the airflow and pressure distribution over and around the airfoil. It opposes or overcomes the force of drag. This type of leading edge device is frequently used in conjunction with trailing edge flaps and can reduce the nose-down pitching movement produced by the latter. The elevator then streamlines, and the nose of the aircraft pitches upward, possibly resulting in a stall. Royal University of Phnom Penh MIS-A2-Group6 Slide: 4-11 2012-2013 1 2. If the linkage between the balance tab and the fixed surface is adjustable from the flight deck, the tab acts as a combination trim and balance tab that can be adjusted to any desired deflection. phak/o. Flashcards. Designed to help minimize a pilot’s workload, trim systems aerodynamically assist movement and position of the flight control surface to which they are attached. 26. Log in Sign up. T-tail designs have become popular on many light and large aircraft, especially those with aft fuselage- mounted engines because the T-tail configuration removes the tail from the exhaust blast of the engines. [Figure 5-11]. The purpose of these design limits is to prevent the pilot from inadvertently overcontrolling and overstressing the aircraft during normal maneuvers. Gravity. Practical Knowledge: Traffic Pattern. The most popular flap on aircraft today is the slotted flap. What term is given to the capability to an aircraft to respond to pilot’s control, especially with, regard to flight path and attitude? The adverse yaw is a result of differential drag and the slight difference in the velocity of the left and right wings. The fixed end of the linkage is on the opposite side of the surface from the horn on the tab; when the trailing edge of the stabilator moves up, the linkage forces the trailing edge of the tab up. glassy-opia. Social Class. 2018. Writing, Storytelling, and Freedom. When the rudder is deflected into the airflow, a horizontal force is exerted in the opposite direction. Been reading Chapter 5 of the PHAK and making notes...but I have a question about stability in regards to CG vs. Center of Pressure. A) In the event engine-driven fuel pump fails. 240 x 5.25 = 1,091 x tangent of X 240 x 5.25 = tangent of X 1,091 1.1549 = tangent of X 49° = X Figure 4-50. The elevator trim tab balances the elevator down spring to position the elevator in a trimmed position. Chapter 6. The split flap is deflected from the lower surface of the airfoil and produces a slightly greater increase in lift than the plain flap.
