EFFECT OF VARIABLE CANT ANGLE ON SWEEPBACK WING [PDF]
Graduate Research in Engineering and Technology, 2022 Winglets are commonly used drag-reduction and fuel-saving technologies in today’s aviation. The primary purpose of the winglets is to reduce the lift-induced drag, therefore improving fuel efficiency and aircraft performance. Traditional winglets are designed as fixed devices attached at the tips of the wings.

Variable Cant Angle Winglets for Improvement of Aircraft Flight Performance [PDF]
Meccanica, 2019 Traditional winglets are designed as fixed devices attached at the tips of the wings. The primary purpose of the winglets is to reduce the lift-induced drag, therefore improving aircraft performance and fuel efficiency. However, because winglets are fixed surfaces, they cannot be used to control lift-induced drag reductions or to obtain the largest ...

Aircraft Control via Variable Cant-Angle Winglets [PDF]
Journal of Aircraft, 2008 This paper investigates a novel method for the control of “morphing” aircraft. The concept consists of a pair of winglets with adjustable cant angle, independently actuated and mounted at the tips of a baseline flying wing. The generalphilosophybehindtheconceptwasthatforspecific flightconditionssuchasacoordinatedturn,theuseoftwo control devices would ...

Aerodynamic Analysis of a Simple Folding Rectangular Wing at Different Cant Angles
Journal of the Institution of Engineers (India): Series CAbstract This paper investigates the aerodynamic effects of varying the cant angle of a simple folding rectangular wing with a NACA2412 cross section. Four different cant angles have been considered at four different Reynolds numbers for this study, taking three values for aspect ratio at three angles of attack. Lift, drag and rolling

Effects of Winglet Cant Angle on Wing Aerodynamics and Aeroacoustics: A Parametric Study
Abstract The use of winglet devices is an efficient technique for enhancing aerodynamic performance. This study investigates the effects of winglet cant angles on both the aerodynamics and aeroacoustics of a commercial wing, comparing them to other significant parameters using a data-driven approach.

A Novel Method to Measure Occlusal Cant Clinically
Journal of Indian Orthodontic Society, 2023 Traditionally occlusal cant angle is measured using a posteroanterior cephalogram. They can also be measured using photographic and 3-dimensional imaging methods. This clinical tip describes an easy method to measure occlusal cant clinically.

Measurements and inferences of raindrop canting angles
Electronics Letters, 2008 The canting angle distribution of raindrops derived separately from a 2-D video disdrometer and from an S-band advanced polarimetric radar are presented. In the former case, measurements were made in both natural and artificial rain. The canting angles showed a symmetric distribution about 0° with a standard deviation (σβ) of 7°–8° in low wind ...

Cumulative crosspolarisation and canting angle distributions
Electronics Letters, 1979 Using measured crosspolarisation against attenuation measurements at 11.6 GHz in three polarisation states over a three-year period and a theoretical rain model, long-term canting-angle statistics are derived. A Gaussian distribution in the normal propagation plane with mean 8.5° and standard deviation 43°, together with a rotation of this plane by an ...
