ARP builds on electronic stability control and its three chassis control systems already on the vehicle – anti-lock braking system, traction control and yaw control. ARP adds another function: detection of an impending rollover. Excessive lateral force, generated by excessive speed in a turn, may result in a rollover.
To increase or decrease overall lift requires that the controls alter the angle of attack for all blades collectively by equal amounts at the same time, resulting in ascent, descent, acceleration and deceleration. A typical helicopter has three flight control inputs: the cyclic stick, the collective lever, and the anti-torque pedals. [2]
In the study of roll stability of vehicles, the static rollover threshold is a key measure. It is expressed as a lateral acceleration in gravitational units. In reality, rollovers are dynamic events; however, there is a strong relationship between roll stability and occurrences of rollover in accidents. [6]
A rollover can also occur as a vehicle crosses a ditch or slope. Slopes steeper than 33% (one vertical unit rise or fall per three horizontal units) are called "critical slopes" because they can cause most vehicles to overturn. [5] A vehicle may roll over when hitting a large obstacle with one of its wheels or when maneuvering over uneven terrain.
The focus on effectiveness over simply showing up, changing workplace cultures that emphasize work-life balance, and technology that enables asynchronous work, also feed into this trend, Fisher noted.
Flight dynamics in aviation and spacecraft, is the study of the performance, stability, and control of vehicles flying through the air or in outer space. [1] It is concerned with how forces acting on the vehicle determine its velocity and attitude with respect to time.
Longer lives. Lifespans have increased by around a decade since the 1960s, putting even more pressure on people to save. The number of Americans 65 and older is projected to increase from 58 ...
A control system includes control surfaces which, when deflected, generate a moment (or couple from ailerons) about the cg which rotates the aircraft in pitch, roll, and yaw. For example, a pitching moment comes from a force applied at a distance forward or aft of the cg, causing the aircraft to pitch up or down.
