fugahumana - Human Flight

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


  • 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…

24/7 Wall St.

The cracked wing problems which Airbus faces on its A 380 super-jumbo are just beginning. The manufacturer’s vice president Tom Williams told Spiegel that “The problem will keep us busy for years.” He estimates the total costs of repairs and special maintenance on the planes will be in the hundreds of millions of euros. Since it appears that the entire fleet of the planes has been affects, that estimate may be low. The comments are also a red flag about Boeing’s (NYSE: BA) problems with its 787 Dreamliner which has had structural issues as well. Some carriers have asked for compensation for the late delivery of the 787. Those same firms may seek more payment for repairs. Boeing’s issues with the 787 could be only at their beginning if they are at all similar to those of the A 380.

FRANKFURT (Reuters) – Airbus will need years to get past problems with wing cracks on its flagship A380 passenger jet, the executive vice president of programs at Airbus told a German magazine.

“This problem will keep us busy for years,” weekly Der Spiegel quoted Tom Williams as saying in an article published on Sunday.

European air safety regulators last month ordered checks for A380 wing cracks for the entire superjumbo fleet after safety engineers found cracks in almost all planes inspected. Read Full Article Here
