A Study for Optimum Condition of Gyrodyne Type Rotary Wing

Rotary-Wing Flight Mechanics

A helicopter is not possessed of an ability to fly fast compared with fixed-wing counterparts. This is a result of considerations with the main rotor. The main rotor moves in a direction very close to its plane of rotation which naturally divides it into two halves which operate under different aerodynamic conditions. One side (called the advancing side) has the rotation and translation velocit...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

Refrigerant Dependent Optimum Clearance For Rotary Compressors

The clearance between the cylinder wall and the rotating piston is critical to the efficiency of a rotary compressor. A large clearance causes internal gas leaks and capacity and efficiency losses. A tight tolerance increases the manufacturing cost. For a given clearance between the cylinder and the rolling piston one can determine a radial and angular offset of the cylinder with respect to the...

a cauchy-schwarz type inequality for fuzzy integrals

نامساوی کوشی-شوارتز در حالت کلاسیک در فضای اندازه فازی برقرار نمی باشد اما با اعمال شرط هایی در مسئله مانند یکنوا بودن توابع و قرار گرفتن در بازه صفر ویک می توان دو نوع نامساوی کوشی-شوارتز را در فضای اندازه فازی اثبات نمود.
