Technical specifications: - axle load (traversable): 18 000 kg, - drive power: 2 x 11 kw, Test speed: 3 km / h, - roll length: 1 150 mm, - roll diameter: 265 mm, - roll axis distance: 475 mm, - security gg: 10 a, - power supply: 3 / n / pe, 400v, 50hz.
During the final phase of flight, the yoke was very difficult to input pitch changes, but was okay in the roll axis. After landing, troubleshooting duplicated the problem.
The goal of this test was to identify data deviation in the measurement of the sensor when the tilt of the roll axis was increasing compared to the values when it was decreasing.
The simplest is the roll axis. As you'd expect, an autopilot that only controls the roll axis can keep the wings level at the simplest, or can possibly be coupled to keep you headed where you want, but it can do so only by working the ailerons.
Setting assumptions for calculation: Lateral acceleration does not generate roll of the car, Rolling of front and rear axle is independent, The position of the centre of the vehicle and the centre of gravity lies in the longitudinal plane of the car, Unsupported masses are negligible, The front and rear axle track is the same, All norms to the roll axis are vertical.
The point O is the intersection of vertical line passing through the centroid of vehicle and roll axis. Based on the vehicle coordinate system with the origin at the point O, the centroid position vector with respect to the point O can be written as [6]-[9]:
The original coordinates are matched with the femoral bone, human roll axis, and the other axis following the right-hand rule, as is shown in Figure 8, where the left and right crus coordinates are L_CK and R_CK, respectively.
The largest miniature models for example, have dynamic load ratings in excess of 16,600 N (LWLG25) and moment load ratings over 320 N-m (MLFG42) in the roll axis. To ensure its miniature bearings keep running smoothly, IKO has integrated its C-Lube long-term lubrication system into many units, which offers a controlled release of lubricant over 20,000 km of operation.
Existing lens-based stablizers can only correct for vibrations on two axes of motions, the pitch axis and yaw axis, even though the most common type of unwanted shaking during photography actually takes place on the roll axis. SmartSensor solves this problem, allowing for image stabilization on three axes, pitch, yaw and the all-important roll.
Incorporating new technologies, Butler National designed, manufactured and obtained Federal Aviation Administration Supplemental Type Certificate (STC) approval of a replacement rate sensor for use by the autopilot on the roll axis and yaw axis of the applicable Learjet 31/35/35A/36/36A/C-21A and 55 Series airplanes, and on the yaw axis on the Learjet Model 24/25/28/29 Series airplanes.
Specifically, it modifies a foot angle about the roll axis and a foot-landing point along the lateral axis so that a swing foot contacts the ground horizontally.
The total torques over the body with respect to the roll axis are given by
