The Lift of a Delta Wing at Supersonic Speeds*

solution of security constrained unit commitment problem by a new multi-objective optimization method

چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...

Oscillating Supersonic delta wing with Straight Leading Edges

A Supersonic similitude has been used to obtain stability derivatives in pitch and roll of a delta wing with straight leading edge for the attached shock case. Ghosh’s strip theory is been used in which strips at different span wise locations are independent of each other. This combines with the similitude to give a piston theory which gives the closed form of solution to stability derivatives ...

Measurements of Zero-Lift Drag at Supersonic Speeds for a Symmetrical Slender Wing Model with Different Roughness Bands

Thw paper gives the results of tests in the A.R.A. 30" x 27" SupersonIc !l!wnel on a slender ogee wing (p = 0'45) to determine the drag at zem lift for the model fitted with vsx~ous alternatwe mughness bands. Tests were made at Mach numbers from M = I.6 to M = 2.4 over a wide range of Reynolds number from about R = 2.5 x IO= to R = 7rlOs,based on the wmg root chord of 2 ft. The results show tha...
