... lowering of the cost of the needed modifications regarding the tooling. Moreover, it also aims to estimate the performance that can be achieved through such modifications. Design/methodology/approach The concept of a master load envelope was applied to facilitate the definition of the airframe parts...

... side force similar to the secondary injection thrust vectoring control method. Numerical simulations were performed by solving Unsteady Reynolds Averaged Navier–Stokes equations with re-normalized group k–ϵ turbulence model. Cylindrical struts of various heights positioned at different locations...

...Yifang Sun; Chunxu Duan; Renfu Li; Chenghu Li Purpose The purpose of this paper is to study the combined effects of inlet airflow temperature and the expansion angle of the upper expansion surface (upper expansion angle) on the performance of the scramjet nozzle. Design/methodology/approach...

... are modelled based on the assumed flight scenario with the aid of a genuine code. And then performance analysis of the engine is performed for each flight path point with the aid of exergy. Findings At the end of the study, major exergy parameters of the engine are calculated during the complete flight...

... and introduced. Findings The proposed TWs model can control the time tolerance within less than 100 s along the passing CPs of a generic trajectory, which is in line with the expected future ATM time-performance requirements. Originality/value The main contribution of this work is the provision...

...Federico Barra; Matteo Scanavino; Giorgio Guglieri Purpose The primary purpose of this study is to analyse the performance of multirotor unmanned aircraft system platforms for passenger transport and compare them with an ordinary helicopter solution. This study aims to define a standard procedure...

... for two aerodynamic configurations of a small UAV. This allowed the investigation of the influence of winglets and classic vertical stabilizers on the platform stability, performance and therefore polar graphs of a small unmanned aircraft. Findings A methodology of flight tests for the assessment...

...Jae-Sang Park Purpose – This paper aims to correlate the flexible multibody analysis for the performance, blade airloads, rotor pitch control angles, and blade structural loads of a full-scale utility helicopter rotor in low-speed forward flight with wind tunnel test and flight test data...

...Abdolrahim Rezaeiha; Tony Schönherr Purpose The purpose of this paper is to comprehensively review most of the significant works ever done worldwide to study the effects of essential parameters on pulsed plasma thruster (PPT) performance and to analyze the effects of each parameter on PPT...
