Effect of Yaw Angle Error in an Aircraft’s Aerial Triangulation

Applied Mechanics and Materials, 2011
Yaw angle Error was excluded in normal ground Triangulation. But in aerial triangulation, Yaw angle error of Direction-Finding (DF) platform is one of important factors which affect location precision. The theoretical GDOP of aerial triangulation is introduced out which included the yaw angle error of DF platform, the general GDOP distributions of ...

Windfarm Power Optimization Using Yaw Angle Control

IEEE Transactions on Sustainable Energy, 2017
In this paper, we extend the Park and Jensen wake model to include the effects of yaw angle rotation and wake deflection of wind turbines. We first perform a numerical study to find the optimal values of induction factor and yaw angle of wind turbines in a single column of a windfarm for achieving the maximum total power with wake effects.

On the yaw-angle characteristics of hot-wire anemometers

Flow Measurement and Instrumentation, 1995
Abstract The directional sensitivity of hot-wire probes depends basically on the velocity and degree of turbulence of the flow as well as on the type of probe used. A velocity/yaw-angle calibration for different types of hot-wire probes is presented. The yaw-angle calibration was performed for a wide range of calibration velocities.

A proposal of AHRS yaw angle correction with the use of roll angle

Aircraft Engineering and Aerospace Technology, 2023
Purpose Attitude and heading are very important measurements on board aircraft. In modern solutions they are measured by the attitude and heading reference system (AHRS). In some small unmanned systems, the GPS track angle is used for heading corrections instead of the magnetometer; then, the system measures the track angle instead of heading.

Estimating Road Angles With the Knowledge of the Vehicle Yaw Angle

Journal of Dynamic Systems, Measurement, and Control, 2010
This paper presents a method of estimating road angles using state observers and three types of sensors (lateral acceleration sensors, longitudinal velocity sensors, and suspension displacement sensors). The proposed method differs from those in most existing literature in three aspects. First, a “full-state” vehicle model is used to describe nonlinear

Lateral Force and Yaw Moment on a Slender Body in Forward Motion at a Yaw Angle

Journal of Offshore Mechanics and Arctic Engineering, 2013
This paper presents a solution method for obtaining the lateral hydrodynamic forces and moments on a submerged body translating at a yaw angle. The method is based on the infinite-fluid formulation of the free-surface random-vortex method (FSRVM), which is reformulated to include the use of slender-body theory.

Effects of Yaw Angle on Aerodynamic Response in Locusts

50th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2012
Aerodynamic forces and moments produced by locusts (Schistocerca americana) were investigated in a low-speed wind tunnel. The experimental setup included locusts mounted on a sensitive six-component microbalance using a sting. Tests were conducted at tunnel speeds of 0, 2, 3, 3.5 and 4 m/s at two body angles of attack and five positive yaw angles at ...

Estimation of the climbing angle in the presence of yawing motion

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2014
The slope angle is one of the most influential factors which limit the control performance and the energy efficiency of not only internal-combustion engine vehicles but also electrified vehicles such as hybrid vehicles and plug-in hybrid electric vehicles.

Yaw Angle Effects on Optimized Riblets

2001
The drag reducing effect of riblets, has been demonstrated previously both experimentally and theoretically. Several aspects of the application of riblet film on an long range aircraft are considered. The aim of the present investigation is to check experimentally the effects of an angle of yaw on the performance of riblets.

Bridge buffeting due to wind with yaw angles

Journal of Wind Engineering and Industrial Aerodynamics, 1992
Abstract The bridge response under turbulent wind with yaw angle, i.e. under a wind not coming from normal to the bridge axis, was studied. Cantilever flat plate models showed a peculiar response which became larger than expected under the wind coming from the free end direction.
