Boeing 787 dream aircraft environmental protection design concept

Boeing's pursuit of environmental performance of products has run through the entire jet era. From the use of fuel, aircraft emissions to community noise, Boeing has made steady progress in a number of environmental factors. With the advent of the 787 Dreamliner, the latest technology introduced by Boeing has brought the environmental performance of civil aircraft to a new level

Boeing has been committed to improving the environmental performance of its products (see Figure 1), because it believes that the cause of environmental damage is the right one. This is especially true for aircraft manufacturers, because one of the reasons people choose to fly is that they can see the colorful natural landscapes on the earth

reduce fuel consumption

with the help of four key technologies, 787 dream 1 First, pull out or turn off the power leads of the hydraulic source of the hydraulic universal testing machine - Industrial Computer - Computer - display - printer, etc. in sequence; I want to save up to 20% fuel than today's aircraft of the same size. These four technologies are: new engines, more use of lightweight composites, more efficient systems and advanced aerodynamic performance. Together, they improve the overall performance of the 787

reduce emissions

carbon dioxide (CO2) is the product of fuel consumption. This means that with the reduction of fuel consumption, carbon dioxide emissions will be reduced by 20%

another key indicator of civil aircraft emissions is nitrogen oxide. Using a complex formula based on the thrust rating of aircraft engines, relevant departments have formulated specific regulations for future aircraft. The designers of the 787 hope that its performance is not only much better than today's requirements and today's requirements, so if the experimental aircraft itself does not have a high-strength aircraft, but also better than the requirements of the future. The Aviation Environmental Protection Committee (CAEP) is formulating stricter regulations for future aircraft

quieter take-off and landing

residents around the airport know that the noise of aircraft taking off and landing is another important indicator of environmental performance Boeing not only makes unremitting efforts to reduce fuel consumption and emissions, but also has been trying to reduce the noise footprint, that is, to reduce the direct impact of disturbing noise

787 Dreamliner adopts a series of new technologies - the most important of which are the engine inlet and sawtooth nacelle with acoustic treatment, that is, the characteristic sawtooth edge at the rear of the engine, efficient aerodynamic shape and other special treatment - to ensure that all 85 dB noise (equivalent to the noisy traffic heard on the roadside) will not exceed the airport boundary. In fact, the noise footprint of the 787 is more than 60% smaller than that of existing aircraft of similar size

realize point-to-point travel

the environmental protection advantage of 787 Dreamliner also comes from its excellent range capability, so airlines can provide more direct flights connecting medium-sized cities. The existing large wide body aircraft has such range capability, but due to its large size, the overall economy is poor when flying routes between medium-sized cities. The medium-sized 787 aircraft can operate efficiently between medium-sized cities, opening up more efficient direct flights without unnecessary takeoff and landing

transporting people more directly to the destination is beneficial to the environment. Direct flights require less fuel and time, which means lower fuel consumption and emissions. Similarly, reducing the number of take-off and landing can reduce the whole noise footprint. And for passengers who need to arrive at the hub airport, reducing transit passenger flow will alleviate the congestion of the airport and route. Research shows that at the hub airport, 30% to 50% of passengers only transit, causing congestion in a city that is neither their departure nor destination, and other negative impacts on the environment

The design intention of

787 is to transport passengers and goods from the place of departure to the final destination in the most environmentally friendly way

new production procedures reduce waste

787 is mainly made of carbon fiber composites. Because this material can be cut like cloth, the leftover materials and waste materials produced by the new production process are reduced. Existing aircraft are mainly made of aluminum. Large or large pieces of materials must be crushed before and after the cement is dried, and then used to manufacture aircraft structures. Generally, 90% of the raw materials used to manufacture aircraft parts become leftover materials in the production process. Although these materials can be recycled, it is undoubtedly a better way to avoid waste as much as possible. The 787 composite solution solves this efficiency problem

in addition, the design team is reducing or no longer using materials that affect the environmental performance of aircraft and are harmful to workers' health as required

finally, new and more environmentally friendly production and maintenance procedures will reduce waste and the use of harmful chemicals and preparations

recycling after decommissioning

Boeing signed a series of agreements and joined the industry cooperation organization established by 19 companies to improve the asset management of old fleet and encourage the recycling of aviation materials and the use of safety and environmental protection. This network, known as the aircraft fleet Recycling Association, provides aircraft owners with a complete set of tools to deal with retired equipment now and in the future

in order to recycle the 787 after its retirement, Boeing is working with other members through the association. Although it is still 30 to 40 years away from the retirement of the first 787, it is necessary to start this work today in order to meet this day

life cycle approach

when designing new models with low noise and stable operation during the most experimental process, Boeing has not forgotten its long-standing commitment to improving the environmental performance of aircraft and its unique life cycle approach. It is because of these factors that Boeing built this ultra efficient civil aircraft. The 787 can become the most successful aircraft model in the history of civil aviation, and its excellent environmental performance is indispensable. Airlines around the world choose 787 because they pursue environmental protection like Boeing. For passengers, they will be able to choose this more comfortable and environmentally friendly model from 2008. (end)
