Can commercial planes break the sound barrier?
In 2029, United Airlines flights will break the sound barrier—and a 26-year hiatus of commercial supersonic flight. The company has bought 15 jets from a startup called Boom Supersonic, whose airplanes break the sound barrier and fly as fast as Mach 1.7. In his video series The Science of Flight, Dr.
Can a piston engine plane break the sound barrier?
In dry conditions, an aircraft needs to be moving at about 767 mph to hit the barrier. Only a few aircraft at the time were even capable of approaching these speeds, and for many years, it was believed that the effects of this barrier would make supersonic travel impossible.
Can a propeller aircraft break the sound barrier?
Propeller planes can probably not break the sound barrier since the propeller, for the airplane to go faster than the speed of sound, must go even faster. This will inevitably cause shock waves powerful enough to even break the propeller.
Why do jet engines have ducted fans instead of propellers?
While I am nor expert on propellers or jet engines I will attempt to answer the question. The reason why ducted fans are used is the turbine in jet engine has an excess power because of the compressor doesn’t need as much power due to dynamic pressure in inlet of the compressor when the airplane flies at high speed.
Are ducted fans better than prop fans?
Ducted fans look cool and they make props look and sound like jets, so people WANT it to be true, but it doesn’t make it so. Ducted fans have about 50-60\% less static thrust than the same size prop if designed badly. If designed absolutely perfectly, they might have 90\% of the efficiency of a prop. But that’s in a static setting.
When did the un-ducted fan go into production?
The un-ducted fan concept never went in production, but it provided a good knowledge base for development of the GE-90 fan blade that went into commercial production in 1995.
Where are the ducted fans located on a plane?
The ducted fans are underneath the circular domes on the wings and another under the shuttered area on the nose for pitch control. Source: http://www.aero-web.org/specs/ryan/xv-5a.htm)
