Klansnik, The Boeing Co. </div> <div class="field-deck"> The 727, latest and smallest of the Boeing family of passenger jets, makes greater use of hydraulic power than the 707 and the 720. Reliability and maintainability studies revealed the areas on which system and component design development should be concentrated. The studies resulted in a greatly improved hydraulic system. </div> <div class="node-body article-body">This article, originally published in the July 1964 issue of Hydraulics & Pneumatics, describes the hydraulic features of the original Boeing 727 airliner.

Nowhere is this bum rap more evident than in motion bases for simulators. </div> <div class="node-body article-body"><p> Motion bases for aircraft and other types of&nbsp; simulators demand a combination of rapid acceleration and deceleration, tight positioning control, long life, and, of course high reliability. The larger the mass that needs to be moved, the more likely the motion base will use hydraulics. Manufacturers have been able to increase the capacity of electromechanical actuators, so they present them as preferable to electrohydraulic systems.</p></div> <p><a href="" target="_blank">read more</a></p> Aerospace Hydraulic Pumps & Motors Tue, 11 Dec 2012 21:01:00 +0000 18021 at Hydraulics handles the hassle of hauling helicopters <div class="field-deck"> Self-propelled hydraulic platform lets single operator move awkward aircraft. </div> <div class="node-body article-body">Because helicopters rise straight up when they take off, they don’t need a long runway to become airborne.
