Aerodynamic drag is the resistance of a vehicle body to motion through the air. A smooth surface has less drag than a rough one. It may be broken down into three main components: skin friction: this is drag due to the surface texture and area. profile drag: this is drag from the three-dimensional shape of … Read more
When we’re mounting an engine either on isolating mounts or solid into a structure it is really important to consider the design of the brackets. If these brackets have any low frequency stiffness concerns then these are likely to be excited by the engine at some point through it’s speed range. There are ten fundamental … Read more
