Constant Lift Coefficient Turns

Journal of Aircraft, 2005
Lateral displacement in a U-turn may become a problem when aircraft position has to be accurately maintained, but the excess thrust is inadequate to sustain level turn of sufficiently small radius. It seems plausible that lateral displacement in a U-turn can be diminished at the expense of mechanical energy: This trade of energy is the subject matter ...

Predicting Maximum Lift Coefficient for Twisted Wings Using Lifting-Line Theory

45th AIAA Aerospace Sciences Meeting and Exhibit, 2007
A method is presented that allows one to predict the maximum lift coefficient for a wing from knowledge of wing geometry and maximum airfoil section lift coefficient. The method applies to wings of arbitrary planform and includes the effects of twist and sweep.

Congruences for fourier coefficients of lifted siegel modular forms I: Eisenstein lifts

Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg, 2005
The author asks the following question: Does a lifting of modular forms preserve congruences for Fourier coefficients? In this paper he gives an affirmative answer in case of the Eisenstein lift. Let \(S^r_k\) denote the space of cusp forms of even weight \(k> 0\) with respect to the modular group \(\Gamma_r\) of degree \(r\).

Drag and lift coefficients evolution of a Savonius rotor

Experiments in Fluids, 1989
The lift and drag coefficients of the rotating Savonius wind machine are determined from the pressure difference measured between the upper plane and the lower plane of a blade. Pressure measurements have been performed for two sets of experiments; the first one for U ∞ = 10 m/s and the second one for U ∞ = 12.5 m/s. In each case it is to be noted that

Congruences for Fourier coefficients of lifted Siegel modular forms II: The Ikeda lifts

Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg, 2007
In part I [Abh. Math. Semin. Univ. Hamb. 75, 97--120 (2005; Zbl 1088.11032)], the author studied whether a congruence for Fourier coefficients of Siegel modular forms is preserved under Eisenstein lifts. Now he proves criteria for the preservation of such congruences under two types of lifts [\textit{T. Ikeda}, Ann. Math. (2) 154, No. 3, 641--681 (2001;

Intelligence Evaluating System of Lift Balancing Coefficient

2015 International Conference on Intelligent Transportation, Big Data and Smart City, 2015
Based on designing the solving algorithm of balancing coefficient, the application system of lift balancing coefficient automatic drawing and printing was develop by using C#.net programming language. On this application system, the graphic chart can be output quickly and accurately by computer.

Lifting based integer wavelet transform with binary coefficients

2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003
A family of lifting based integer wavelet transform (IWT) that is parametrised in a simple manner by one free parameter is presented in this paper. The coefficients of the lifting filters in this family are binary numbers and therefore can be implemented efficiently without using any multipliers.

Lift coefficient of a stationary sphere in gradient flow

Journal of Hydraulic Research, 1994
This paper deals with the lift force on a stationary sphere close to and away from the boundary and supplements an earlier paper which dealt with the study of the drag force. The experimental setup, instrumentation, nature of boundaries, sizes of test sphere, ranges of Reynolds number and relative size of the sphere are all common to both the studies ...

Lift Coefficient Variation on a Cylinder Forced to Oscillate

4th International Symposium on Fluid-Structure Interactions, Aeroelasticity, Flow-Induced Vibration and Noise: Volume I, 1997
Abstract The instantaneous pressure distribution around the azimuth of a cylinder undergoing forced oscillations is measured using an array of 18 miniature microphones. The microphones were placed at the midspan of the cylinder with 20 degree increments between each sensor. The Reynolds number for the experiments was 13,800. The cylinder
