TAKEOFF RUN: During the takeoff run the plane accelerating from 0 km/h to VP with CONSTANT acceleration. During takeoff the reaction at nose gear B, will decrease due to this acceleration. The more acceleration, the less reaction at B. If the acceleration is high enough the nose gear may prematurely leave the ground which is not acceptable before reaching to the take-off speed. Calculate the minimum length of the runway of this part of run, to make the reaction at the nose wheel (B) to be zero, Fb = 0 N. Neglect all the aerodynamic forces (No lift, no drag). mT = 196000 kg mL = 158000 x0=18 m x2=2.4 m y0=2.9 m y2=1.6 m VP=56 km/h VS=180 km/s
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
TAKEOFF RUN: During the takeoff run the plane accelerating from 0
km/h to VP with CONSTANT acceleration. During takeoff the reaction at
nose gear B, will decrease due to this acceleration. The more
acceleration, the less reaction at B. If the acceleration is high enough the
nose gear may prematurely leave the ground which is not acceptable
before reaching to the take-off speed. Calculate the minimum length of
the runway of this part of run, to make the reaction at the nose wheel
(B) to be zero, Fb = 0 N. Neglect all the aerodynamic forces (No lift, no
drag).
