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 300 million pound deal in principle ( subject to acceptable EPC) with the environmental and waste management company Bee'ah to build a thermal energy-from-waste facility in Sharjah, UAE. If the project proceeds, the deal is expected to create around 200 British jobs and secure another 650. On November 18, 2015, Chinook Sciences was honoured to win the Power/Energy category at the Institute of Engineering and Technology Awards in London. Chinook Sciences Chinook Sciences is a US and UK based technology company that specializes in waste to energy and metal recovery.
