A slipstream is a region behind a moving object in which a wake of fluid (typically air or water) is moving at velocities comparable to that of the moving object, relative to the ambient fluid through which the object is moving. [1] The term slipstream also applies to the similar region adjacent to an object with a fluid moving around it.
Drafting or slipstreaming is an aerodynamic technique where two moving objects are aligning in a close group to exploit the lead object's slipstream and thus reduce the overall effect of drag. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline 's average energy expenditure ...
A slipstream processor is an architecture designed to reduce the length of a running program by removing the non-essential instructions. It is a form of speculative computing . Non-essential instructions include such things as results that are not written to memory, or compare operations that will always return true.
The nature of slipstreaming means that it involves an initial outlay of time and work, but can save a lot of time (and, by extension, money) in the long term. This is ...
Diagram showing yaw string deflection on a multi-engine airplane flown incorrectly with wings level after an engine failure. The yaw string, also known as a slip string, is a simple device for indicating a slip or skid in an aircraft in flight.
Increasing the number of blades also decreases the amount of work each blade is required to perform, limiting the local Mach number – a significant performance limit on propellers. The performance of a propeller suffers when transonic flow first appears on the tips of the blades. As the relative air speed at any section of a propeller is a ...
Rote work, anything where the job requires you to stay in a lane—probably a no-go. That’s why I’d wager that oldest children probably don’t want to go into accounting—unless you’re on ...
Deflected slipstream is an approach to creating an aircraft that can take off and land vertically (), or at least with a very short runway ().The basic principle is to deflect the slipstream from one or more propellers approximately 90 degrees, to create an upward thrust for vertical takeoff and a downward air cushion for landing.
