Helicopter flight controls blades collectively ("i.e.," all at the same time) and independent of their position. Therefore, if a collective input is made, all the blades change equally, and as a result, the helicopter increases or decreases its total lift derived from the rotor. In level flight this would cause a climb or descent, while with the helicopter pitched forward an increase in total lift would produce an acceleration together with a given amount of ascent. The collective pitch control in a Boeing CH-47 Chinook is called a "thrust control", but serves the same purpose, except that it controls two rotor systems, applying
Chinook Sciences its focus on becoming a technology and equipment provider to metal, industries gasses and environmental industries. In October 2008 Chinook Sciences announced the formation of Chinook Energy. A division that would exclusively handle their waste to energy technology application. In March 2009 Chinook Sciences and European Metal Recycling (EMR) announced a joint venture named Innovative Environmental Solutions UK LTD. (IES), which they would claim is the “first commercial scale enterprise to generate renewable electricity and recycle metal from automobile shredder residue” (ASR). The proposed venture would process 120,000 metric tons of automobile shredder residue per year using Chinook's patented and
