There was once a glorious time in vehicular history when seemingly everyone was obsessed with gas turbines. These smooth ...

Paris Airshow observers might be wondering where the new, exciting jetliners are. There’s been a drought of announcements.

Two of the more commonly used engines are turbofan and turbojet engines. They have a lot of similarities, such as their function of sucking in cool air through the front and pushing that air out ...

Neck fans, which look somewhat like headphones but with fans instead of audio equipment in their ends, promise to be the solution to my (and much of America’s) misery. One listing claims it will ...

The U.S. Federal Aviation Administration issued an air-worthiness directive requiring commercial operators of Pratt & Whitney PW1100G-JM and PW1400G-JM geared turbofan engines to conduct ultrasound ...

Abstract: Airfoil shape generation and optimization are the important aspects of aircaft design. One of the important parameter that defines the efficiency of airfoil design is the lift vs drag ratio.

In this study, the effect of different blade shapes on the aerodynamic performance of NACA series airfoils under a wide variety of working conditions at Reynolds number Re = 700,000 was explored. The ...
