fugahumana - Human Flight

FugaHumana has moved! Please visit the Aerospace Engineering Blog.

Part 1 of this blog series outlined the different sensing mechanisms that aquatic animals possess to create spatial images of the flow fields around them. In summary fish were found to possess a network of mechanosensors distributed over their bodies called the lateral line. The lateral line consists of two separate sensory subsystems:

  • a system of velocity-sensitive superficial neuromasts that responds to slow, uniform motions and that integrates large scale stimuli at the periphery such as constant currents

and

  • a system of acceleration- or pressure-gradient-sensitive canal neuromasts that responds to rapidly changing motions and gives the fish the opportunity to orient towards sources such as prey or optimize swimming speed or tail-flapping frequency.

In this post I will give a brief overview of general hydrodynamic theory and specifically the flow patterns that swimming fish are expected to sense with…

NASA Makes Breakthrough in Sonic Boom Reduction

Image

It has been publicly known that NASA has been testing methods to reduce the sonic boom signature of jets. Tests have been underway with Boeing and Lockheed Martin to achieve this goal and it was just released that their has been a “breakthrough” in testing!

Quoted from a NASA representative:

“This is a breakthrough. It’s the first time we have taken a design representative of a small supersonic airliner and shown we can change the configuration in a way that is compatible with high efficiency and have a sonic signature than is not a boom,”

2025 could be the reemergence of Concorde-travel. I’d love to feel this “new boom,” because when I was at Edwards Air Force base last month, the boom I experience definitely wasn’t subtle and wouldn’t gain nationwide acceptance.

Either way, great job America!

Could this possibly be related to the “small earthquakes in Wisconsin?” The boom in the video definitely sounds like the sonic boom I heard at Edwards. Check out the video and tell me what you think.

Virgin Galactic April Fools: Virgin Volcanic

Image

Richard Branson launched his new project yesterday: Virgin Volcanic. The information came out yesterday so I was definitely not thinking about april fools just yet. It took me a minute to figure out what was going on and I got a great laugh out of it. Check out the official announcement on the Virgin Galactic website.
