Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology [1] [2] that improves a vehicle's stability by detecting and reducing loss of traction . [3]
The period is usually on the order of 3–15 seconds, but it can vary from a few seconds for light aircraft to a minute or more for airliners. Damping is increased by large directional stability and small dihedral and decreased by small directional stability and large dihedral.
Stability derivatives, and also control derivatives, are measures of how particular forces and moments on an aircraft change as other parameters related to stability change (parameters such as airspeed, altitude, angle of attack, etc.). For a defined "trim" flight condition, changes and oscillations occur in these parameters.
The Accord also won Car and Driver's 10Best trophy in 2008 and 2009, a total of 23 times in the nameplate's history, winning it more times than any other vehicle by far. US sales have been up 9.4%, as SUV buyers shift to the V6 Accord. [50] The 2008 - 2011 Honda Accord was awarded a best-in-class rating of 4 1/2 stars by the JB car pages. [51]
The longitudinal stability of an aircraft, also called pitch stability, [2] refers to the aircraft's stability in its plane of symmetry [2] about the lateral axis (the axis along the wingspan). [1] It is an important aspect of the handling qualities of the aircraft, and one of the main factors determining the ease with which the pilot is able ...
The three axes of rotation in an aircraft. Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw.
[2] [1] Equally, the system is commonly disengaged prior to landing, as it could inhibit the control authority to the pilot at the critical moment of touchdown. On several modern aircraft that are outfitted with a yaw damper, these systems become engaged automatically once the aircraft has surpassed a set altitude (e.g. 200 feet); older ...
Grumman F-14 Tomcat jet fighter during a takeoff, with stabilators deflected upwards. A stabilator is a fully movable aircraft horizontal stabilizer.It serves the usual functions of longitudinal stability, control and stick force requirements [1] otherwise performed by the separate parts of a conventional horizontal stabilizer (which is fixed) and elevator (which is adjustable).
