Model of Unsteady Aerodynamic Coefficients of a Delta Wing Aircraft at High Angles of Attack

Several approaches for modelling the longitudinal aerodynamic coefficients of a fighter aircraft at high angles of attack, including the unsteady effects are presented. A traditional approach where the model of the coefficient arises in the form of the steady and unsteady effects, the unsteady effect being modelled by means of transfer functions. The second approach uses an internal variable de...

determination of olanzapine and thiourea using electrodes modified by dna and film of copper-cobalt hexacyanoferrate & investigation of electro-oxidation of some catechol derivatives in the presence of 4-phenylsemicarbazid

چکیده هدف از این کار بررسی الکترواکسیداسیون کتکول و مشتقات آن در حضور 4-فنیل سمی کاربامازید بوده است اکسیداسیون کتکولها ترکیبات نا پایدار کینونها را تولید می کنند که این ترکیبات می تواند در واکنش مایکل بعنوان پذیرنده نوکلئوفیل عمل نمایند. در ادامه اکسایش کتکولهای (a-c1) را درحضور 4-فنیل سمی کاربامازید در محلول آب/استونیتریل (90/10)بوسیله ولتامتری چرخه ای و کولن متری در پتانسیل ثابت مورد بررسی ...

A Practical Method for Investigation of Aerodynamic and Longitudinal Static Stability of Wing-in-Ground Effect

The purpose of this paper is to present a fast, economical and practical method for mathematical modeling of aerodynamic characteristics of rectangular wing-in-ground effect (WIG). Reynolds averaged Navier-Stokes (RANS) equations were converted to Bernoulli equation by reasonable assumptions. Also Helmbold's equation was developed for calculation of the slope of wing lift coefficient in ground ...
