Lift distribution in a rectangular jet [PDF]

open access: yes, 1971
Computer programs predict effect of slipstream-wing flow interaction on aerodynamic characteristics of deflected slipstream and tilt aircraft. One program calculates lift distribution, lift, and drag of wing in wide slipstream. Results permit development

A comparison of coaxial and conventional rotor performance [PDF]

open access: yes, 2009
The performance of a coaxial rotor in hover, in steady forward flight, and in level, coordinated turns is contrasted with that of an equivalent, conventional rotor with the same overall solidity, number of blades, and blade aerodynamic properties.

Aerodynamic Drag and Gyroscopic Stability

open access: yes, 2013
This paper describes the effects on aerodynamic drag of rifle bullets as the gyroscopic stability is lowered from 1.3 to 1.0. It is well known that a bullet can tumble for stability less than 1.0. The Sierra Loading Manuals (4th and 5th Editions) have previously reported that ballistic coefficient decreases significantly as gyroscopic stability, Sg, is

A method for the reduction of aerodynamic drag of road vehicles [PDF]

open access: yes
A method is proposed for the reduction of the aerodynamic drag of bluff bodies, particularly for application to road transport vehicles. This technique consists of installation of panels on the forward surface of the vehicle facing the airstream.

CME dynamics using STEREO & LASCO observations: the relative importance of Lorentz forces and solar wind drag

open access: yes, 2017
We seek to quantify the relative contributions of Lorentz forces and aerodynamic drag on the propagation of solar coronal mass ejections (CMEs). We use Graduated Cylindrical Shell (GCS) model fits to a representative set of 38 CMEs observed with the SOHO

Active Flow Control by Coanda Actuators for Aerodynamic Drag Reduction in a European-Type Truck

open access: yesActuators
Heavy vehicles present high aerodynamic drag. This results in significant fuel consumption and, consequently, high emissions of harmful substances. This study examines the variation in aerodynamic drag in a European-type truck with different trailer ...

Drag reductions obtained by modifying a box-shaped ground vehicle [PDF]

open access: yes
A box-shaped ground vehicle was used to simulate the aerodynamic drag of high volume transports, that is, delivery vans, trucks, or motor homes. The coast-down technique was used to define the drag of the original vehicle, having all square corners, and ...
