New Aerodynamic Studies of an Adaptive Winglet Application on the Regional Jet CRJ700

open access: yesBiomimetics, 2021
This study aims to evaluates how an adaptive winglet during flight can improve aircraft aerodynamic characteristics of the CRJ700. The aircraft geometry was slightly modified to integrate a one-rotation axis adaptive winglet.

Aerodynamic characteristics of a quadcopter with propellers [PDF]

open access: yesAIP Conference Proceedings, 2021
The characteristics performance of the small quadcopter was measured in a wind tunnel. The effect of propellers on the lift and drag of the quadcopter frame has been found. The quadcopter descent stage was investigated numerically by the RANS approximation.

Calculation and analysis of aerodynamic characteristics for airfoils immersed in two-dimensional jet flow

open access: yesXibei Gongye Daxue Xuebao, 2022
In order to study the aerodynamic interaction of the airfoil and jet flow, the free streamline model and the panel method are combined to establish a calculation method for the aerodynamic characteristics of the airfoil in a two-dimensional inviscid jet ...

In Vivo Aerodynamic Characteristics of the Nijdam Voice Prosthesis [PDF]

open access: yesActa Oto-Laryngologica, 1997
The Nijdam voice prosthesis is an indwelling valveless voice prosthesis for postlaryngectomy voice rehabilitation. The in vitro aerodynamic characteristics are reported to be comparable to that of the low-resistance Groningen voice prosthesis. Owing to the design of the prosthesis the airflow resistance depends on the shaft length of the voice ...

Computational and experimental investigation into aerodynamic interference between slender bodies in supersonic flow [PDF]

open access: yes, 2011
Aerodynamic interference can occur between high-speed bodies when in close proximity. A complex flowfield develops where shock and expansion waves from a generator body impinge upon the adjacent receiver body and modify its aerodynamic characteristics.

An Improved Nonlinear Aerodynamic Derivative Model of Aircraft at High Angles of Attack

open access: yesInternational Journal of Aerospace Engineering, 2021
The classical aerodynamic derivative model is widely used in flight dynamics, but its application is extremely limited in cases with complicated nonlinear flows, especially at high angles of attack.
