Volume 16, Issue 1 , June 2023, , Pages 146-158

Abstract
  The compressor blade is responsible for increasing the flow pressure. By adding a blade behind the main blade, the compressor performance can be improved by increasing the pressure ratio and reducing the weight. The tandem improves the performance and increases the compressor absorption coefficient by ...  Read More

Rotor Sizing of Helicopters Using Statistical Approach

فرید شاهمیری

Volume 10, Issue 1 , March 2013

Abstract
  This paper is concerned with the statistical model development issues, necessary for rapid estimation of the rotor sizing for single main rotor helicopters at the preliminary design stage. However, Central Composite Design (CCD) method, simulation-based data collection, linear regression analysis, mathematical ...  Read More
