Journal ArticleDOI
TL;DR: In this paper, the authors present the major approaches and results obtained in recent years and to point out existing deficiencies and possibilities for improvements for the prediction of dynamic stall in aerodynamic bodies such as airfoils and wings.

Journal ArticleDOI
TL;DR: An overview of developments in the field of supersonic jet screech can be found in this article, including a historical background, summary of recent developments, and a critical assessment of the current understanding of screech.

Journal ArticleDOI
TL;DR: Small-crack theory has unified “fatigue” and “fracture mechanics” concepts; and has bridged the gap between safe-life and durability/damage-tolerance design concepts, so that fatigue damage can now be characterized by “crack size”.

Journal ArticleDOI
TL;DR: In this paper, a review of experimental and computational methods used for simulation of ice accretion on aircraft flying through icing conditions is presented, along with some of the physical phenomena known to be important in glaze icing.

Journal ArticleDOI
TL;DR: In this paper, a zonal, upwind, implicit, factored algorithm is used to solve both the mean flow equations and the turbulence model equations for three-dimensional, compressible turbulent flow.

Journal ArticleDOI
TL;DR: In this article, a preliminary design procedure is presented for an SFRJ-assisted gun launched projectile of pseudo-vacuum trajectory, where two different types of regression rate mechanism are discussed: one controlled by the heat transfer processes downstream of the reattachment region and the other by that in the region itself.

Journal ArticleDOI
TL;DR: In this paper, the state of the art on prediction methods and control techniques available for the propagation of impulse noise from sources such as blasting, high speed train in a tunnel, sonic boom, muzzle blast and engine exhaust are described.

35 citations


Journal ArticleDOI
TL;DR: In this article, a numerical simulation of low Reynolds number turbulent flow over streamwise aligned micro-grooved striations or riblets and the application of a near-wall viscous model to the flow over more complicated riblet shapes (V and U groove, thin element, compound and spanwise non-continuous V-groove) are assessed.

Journal ArticleDOI
TL;DR: A review of the various vortical-flowfield studies with which the author has been involved, first with attached and separated-vortical flows, is given in this article, along with an estimate from computational fluid dynamics, and experimental results from wind tunnel and flight are presented.

Journal ArticleDOI
TL;DR: In this article, a numerical method is described to demonstrate the main features of the technology in a form suitable for routine use in the wind tunnel and the main parts of this technology are: (1) the second-order monotone method developed in Russia; (2) patches technology for surface creation; (3) multiblock irregular grid generator; (4) color post-processor.

Journal ArticleDOI
TL;DR: A survey of the present state of knowledge in the field can be found in this paper, where various theories derived for the prediction of base pressure in steady base flow are discussed, including some old and several new contributions developed in the 1990s of this century.

Journal ArticleDOI
L.C. Squire1
TL;DR: This paper reviewed the contribution made to aeronautical research by workers using the high-speed blowdown tunnels in the Engineering Department at Cambridge and concluded that workers using small high speed tunnels still have a significant role to play in aerospace research in spite of recent developments in tunnel design which have lead to a new generation of efficient large tunnels in which model tests on aircraft at near flight Reynolds numbers are possible.

Journal ArticleDOI
TL;DR: In this paper, the development of fighters integrated with their stores is reviewed, with the main aerodynamic effects of stores being higher drag (store much reducing operational area), store trajectory disturbed at release (missing target or even colliding with aircraft), and reduced performance and agility of loaded aircraft.
