Effect of Solidity and Camber Angle on Performance in Contra-rotating Open Rotor Design [PDF]

open access: yesJournal of Applied Fluid Mechanics
In this paper, an aerodynamic design method for a contra-rotating open rotor based on lifting line theory is presented. By changing the number of blades, the solidity and camber angle are changed, and several different aerodynamic designs are completed ...

Solidity of viscous liquids. IV. Density fluctuations [PDF]

open access: yes, 2006
This paper is the fourth in a series exploring the physical consequences of the solidity of highly viscous liquids. It is argued that the two basic characteristics of a flow event (a jump between two energy minima in configuration space) are the local ...

Seed Geometry in Species of the Nepetoideae (Lamiaceae)

open access: yesHorticulturae
The Nepetoideae are a subfamily of the Lamiaceae with 124 genera in three tribes: Elsholtzieae, Mentheae and Ocimeae. Their seeds have variable shapes, described in the literature by using adjectives derived from geometry, such as ellipsoid or elliptic ...

Mars Science Helicopter Conceptual Design [PDF]

open access: yes, 2020
Robotic planetary aerial vehicles increase the range of terrain that can be examined, compared to traditional landers and rovers, and have more near-surface capability than orbiters. Aerial mobility is a promising possibility for planetary exploration as
