A single airplane with 250 people on board STILL creates less air pollution than 250 people each driving their own cars for the same distance. Yes, an airplane DOES burn a lot of fuel, but MOST of that is within the first 20-30 minutes of the flight during takeoff and climb. Once they reach cruising altitude, they reduce power (AND fuel consumption) and pretty much coast for the rest of the flight, while a car continues to burn the same amount of fuel for every mile you drive it. All you fools who are worried about overseas flights haven't considered that there are many more DOMESTIC flights than those going overseas. |
| Question: What are the strengths and weaknesses of biplane vs monoplane design? Posted: 23 Sep 2016 08:45 PM PDT As an aircraft scales up, its weight goes up as the cube of the scale, while the wing area goes up only as the square. Double an airplane size in all dimensions and it will be 8 times the mass but only will have 4 times the wing area (and accordingly 4 times the lift at a given speed). Early planes did not fly fast, and since they are quite large compared with birds, would need proportionally longer wings that a scaled bird has. Structurally, a very long and thin wing (like those on sailplane) are heavy and fragile. So it made sense to cut the wing in two chunks and stack those on top of one another: the wings became stubbier and thus easier to build, cross- bracing would ensure rigidity, while the shorter span would improve maneuverability. As planes started flying faster, the need of very large wing reduced (on the other hand, it required longer takeoff and landing runs, as those would be done at a higher speed) and flaps were added to increase the area for the take off and landing phases. Material were changed (wood and fabric were replaced with metallic alloys and more recently composites) allowing a wing to be made larger without too much weight, and the need for a biplane configuration went away. For the record, the first aircraft to fly across the English channel in 1909 (Louis Bleriot) was a monoplane. Deperdussin was also producing monoplane aircraft before the first world war, so it was not all the planes of that time that were biplanes. |
