The company was originally incorporated on 28 January 1933, and as Vent-Axia Limited private company on 4 April 1936, to produce and sell ventilation equipment. [2] [3] During the Second World War, the company made fans for 10 Downing Street. [4] In 1946, the company acquired a new factory in Putney with 18,000 square feet (1,700 m 2) of floor ...
The Sentinel A4 is a complete redesign of the sensor that uses digital processing and solid-state antenna modules based on gallium nitride (GAN) transmitters. The scalable modular architecture is shared with the long-range AN/TPY-4 radar, which has 1000 individually controlled elements and uses GPU computing for signal processing.
Figure 1: Components of a centrifugal fan An external motor belt driven inline centrifugal fan discharging inline to the exterior of a building through a duct. Unlike non-inline/non-concentric impeller casing design with a cutoff blade above, the concentrically symetric cylinder casing and impeller geometry of inline type redirects the outflow around so that it is parallel to the inflow of gases.
The LGM-35 Sentinel, also known as the Ground Based Strategic Deterrent (GBSD), is a future American land-based intercontinental ballistic missile system (ICBM) currently in the early stages of development. [3] [4] It is slated to replace all 450 Minuteman III missiles from 2029 through 2075. The Minuteman missiles are currently stationed in ...
In mechanical engineering, a kinematic diagram or kinematic scheme (also called a joint map or skeleton diagram) illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as geometric objects, such as lines, triangles or squares, that support schematic ...
ATA 100 contains the reference to the ATA numbering system which is a common referencing standard for commercial aircraft documentation. This commonality permits greater ease of learning and understanding for pilots, aircraft maintenance technicians, and engineers alike.
The Lockheed Martin RQ-170 Sentinel, nicknamed Wraith, [2] is an American unmanned aerial vehicle (UAV) developed by Lockheed Martin and operated by the United States Air Force (USAF) for the Central Intelligence Agency (CIA).
The JPL mobile robot ATHLETE is a platform with six serial chain legs ending in wheels. The arms, fingers, and head of the JSC Robonaut are modeled as kinematic chains. The movement of the Boulton & Watt steam engine is studied as a system of rigid bodies connected by joints forming a kinematic chain.
