Boeing Granted Patents On Quiet Technology

Are these patent diagrams a view into the future of aeroplane design? – Deskarati –

Boeing was recently granted patents on a number of ideas pointing to a focus on quiet airliners in the future. The main concept includes shielding the engines from the ground by placing them above the wing or fuselage. In its filings with the United States Patent Office, Boeing also mentions the capability of reducing the heat signature of an aircraft from the ground is also possible using the creative engine placement. The reason for shielding the heat is spelled out clearly in patent 7,900,865.

“Heat is undesirable particularly in both military and civil aircraft, which may be tracked by ground-based missiles that seek heat in the form of infrared radiation.”

Another noticeable feature of the design is the forward swept wings and the use of canards at the front of the aircraft. The idea of shielding engine noise from the ground has also been explored by Airbus in a concept unveiled last year.

In addition to the somewhat unconventional looking ideas above, Boeing was also granted patent 7,900,868 which also focuses on reducing the sound of an aircraft as heard from the ground. This patent also puts the engines on top of the wings. But instead of using an all new design, a more traditional design is simply altered with the engines mounted on an extended wing platform near the fuselage.

    Have a look at – or even make it a Deskarati subject – this is a really interesting development in aeronautics – the body contributes lift and look where the engines are – not dissimilar to Boeing’s patent.

    I WAS HORRIFIED. May be Steve can put me right. They are going to attach small French ducks to the wings? I knew a canard was also a story of dubious authenticity put about to discredit someone, like the idea that a certain Physics professor handed out spliffs to his interview panel before they appointed him to his chair. I did not know a canard was part of an airyplane. Is it anywhere near the fuselage or nacelle?
