Download E-books Why Don't Jumbo Jets Flap Their Wings?: Flying Animals, Flying Machines, and How They Are Different PDF

What do a bumble bee and a 747 jet have in universal? It’s no longer a trick query. as a matter of fact they've got quite a bit in universal. They either have wings. They either fly. And they’re either supreme to it. they simply do it differently.

Why Don’t Jumbo Jets Flap Their Wings? deals a desirable clarification of ways nature and human engineers every one arrived at powered flight. What emerges is a hugely readable account of 2 very various ways to fixing a similar primary difficulties of relocating in the course of the air, together with carry, thrust, turning, and touchdown. The publication strains the gradual and planned evolutionary strategy of animal flight—in birds, bats, and insects—over thousands of years and compares it to the directed efforts of people to create the airplane over the process a unmarried century.

Among the numerous questions the e-book answers:

  • Why are wings invaluable for flight?
  • How do assorted wings fly differently?
  • When did flight evolve in animals?
  • What imaginative and prescient, wisdom, and expertise used to be wanted ahead of people may perhaps learn how to fly?
  • Why are animals and aircrafts ideally suited to the type of flying they do?

David E. Alexander first describes the fundamental homes of wings ahead of launching into the varied demanding situations of flight and the suggestions of flight aerodynamics and keep watch over to give an built-in view that exhibits either why birds have traditionally had little impression on aeronautical engineering and interesting new parts of expertise the place engineers are effectively borrowing rules from animals.
