Biplane to break the sound barrier

biplane 3456

Cheaper, quieter and fuel-efficient biplanes could put supersonic travel on the horizon.

For 27 years, the Concorde provided its passengers with a rare luxury: time saved. For a pricey fare, the sleek supersonic jet ferried its ticketholders from New York to Paris in a mere three-and-a-half hours — just enough time for a nap and an aperitif. Over the years, expensive tickets, high fuel costs, limited seating and noise disruption from the jet’s sonic boom slowed interest and ticket sales. On Nov. 26, 2003, the Concorde — and commercial supersonic travel — retired from service…

NASA’s Supersonic Green Machine – Futuristic Jet Designed to Minimize Sonic Boom

green machine jet

The jet is designed to be far more fuel-efficient than Concorde with a greatly reduced sonic boom.

It looks like a plane designed for a superhero or an invading alien force. But this sleek, green aircraft could one day be the supersonic jet of the future.

Where Russian Supersonic Jets Go To Die

Some parts of the plane still work!

Tu-144 which first flew on 31 December 1968 (two months before Concorde) is the fastest supersonic commercial airliner ever made. Despite the similarity of the Tu-144 to Concorde, there were significant differences in the control, navigation and engine systems. The Tu-144 was in some ways a more technologically advanced aircraft, but in areas such as range, aerodynamic sophistication, braking and engine control, it lagged behind Concorde.  A total of 16 airworthy Tu-144s were built, Aeroflot had only made 55 scheduled passenger flights with their Tu-144s before they put them out of service.  (PICS)

Virgin Galactic Will Fly You To Space And Monitor The Climate

Virgin Galactic Will Fly You To Space And Monitor The Climate 

 Virgin Galactic’s WhiteKnight

Virgin Galactic’s WhiteKnightTwo and SpaceShipTwo aircraft will be doing the world a favor when they start flying paying passengers into space: they’ll be carrying sensors aboard to monitor greenhouse gases at a little-monitored altitude. The National Oceanic and Atmospheric Administration has just signed a deal with Virgin to let it install sensors on the two vehicles, since it turns out that they will be one of the few aircraft that fly at around 50,000 feet. Most aircraft, with the exception of the sadly gone Concorde, fly below this altitude, and scientists would like to get their hands on air data from this height to help with environmental monitoring.
