BA, LMT - The Jets Of The Future

Fri Apr 20, 2012 7:34 am

NASA asked the world’s top aircraft engineers to solve the hardest problem in commercial aviation: how to fly cleaner, quieter and using less fuel. The prototypes they imagined may set a new standard for the next two decades of flight.

The goal...Well...to save fuel, by 50% to today's engine fuel consumption. Within the studies for supersonic travel, Lockheed Martin (LMT) proposed two planes. And Boeing (BA) proposing one.

1. BOX WING JET, LOCKHEED MARTIN (Target Date: 2025)
2. SUPERSONIC GREEN MACHINE, LOCKHEED MARTIN (Target Date: 2030)
3. SUGAR VOLT, BOEING (Target Date: 2035)


1. The Box wing Jet

Features:
- ditched conventional turbofan engines
- Box Wing concept
- lightweight materials (Composites)

The studies show the Box wing concept shows 16% more efficient than regular wings today due to higher lift-to-drag ratio. Engines showing 22% more efficiency. Thoughts?

2. Supersonic Green Machine (I really like this concept)

Features:
- Concorde like replacement reaching proposed Mach 1.6.
- The plane’s variable-cycle engines would improve efficiency by switching to conventional turbofan mode during takeoff and landing.
- Combustors built into the engine would reduce nitrogen oxide pollution by 75 percent.
- inverted-V tail and underwing engine placement would nearly eliminate the sonic booms

This plane was designed in 2010.

3. Sugar Volt (Boeing)

Features:
- It's a hybrid plane! It would draw energy from both jet fuel and batteries during takeoff, but once at cruising altitude, pilots could switch to all-electric mode
- Longer, thinner wing...Hear me out...That folds UPWARDS. Boeing engineers thought “By making the wing thinner and the span greater, you can produce more lift with less drag"
- A 737 sized, 3,500 NMI ranged prop plane. 757 replacement? Sugar-Volt-900ER?  

Thoughts: It's interesting to see that Airline Manufacturers are thinking of the future. But do you guys think these planes could fly? One of Boeing's main purpose in canceling the sonic cruiser was because of oil prices.Do you think LMT could pull off another Concorde like plane? I'm excited, but I know I shouldn't be.I just can't imagine planes looking so different, but I think it would be awesome seeing a change, just like the Concorde.

I would have said they only asked some of the "world’s top aircraft engineers", a lot of them do not work for LM or BA, and a lot of them do not work in the USA.

NASA only asked top US plane makers. It would've been interesting seeing Airbus concept
