If planes are already made, then howcome scientist can not just use the same technology to make a car fly?

Answer 1

The requirements are too different. An airplane needs to have a considerable wingspan to fly efficiently; on the road, this would be a major nuisance. The power train on a car (transmission, drive wheels, etc.) is quite heavy, and weight on an airplane is bad news. Light airplanes have no transmission at all -- the engine is connected directly to the propeller, and it's hard to get much lighter than that. A fellow named Moller has been working on an air car for decades, but his physics is bad, and his vehicles do not have sufficient wingspan to fly efficiently -- they rely on fans, of no great size, which are horribly inefficient.

Answer 2

I think the reason that a flying car is not produced yet is, the airodynamic principle that make a plane fly need a high speed motion of the plane (given the shape of the wing, the nose and tale of the plane which are all intended to create an air pressure that support the plane from below and reduce the pressure from the top while the plane is moving at a higher speed) while these things are difficult to be implemented with cars which are mostly for relativly short distance tripes. otherwise you can call those very small planes cars.

Answer 3

There have been several cars that can also fly.. See Popular Mechanics magazine......

One reason that the idea never took hold is ...among other things....the expense.

Another reason is the fact that the wings create a storage problem when not in use and they have to stay with the car or the whole idea flops.

It would be better if engineers could make a car that would last a long time, run on inexpensive fuel other than gasoline and have some really good built in safety features.

Answer 4

A plane flies by creating lift, where the pressure above the plane is much less than that below it, causing it to fly. This is done by the wings, where they are designed to create an air flow to reduce the pressure above them. The airflow is created by moving the plane moving forward.

For a car to fly you would need a surface area to create the lift, plus a power source that can pusch the car forward to create the airflow. Hence once it took off the wheels could not be the driving force as they would not be in contact.

Answer 5

You need wings, a rocket engiine, or rotors to fly. Wings on cars would cause major accidents with the current roadway systems. A rocket engine on cars will result in a lot of burning incidents, and you'd still need wings to control the car's flight. Rotors on a car would result in alot of down tree limbs and power lines, and even accidental beheadings. So, conceptionally it wouldn't be hard to mass produce a flying car. Realistically, there's no place in the developed world for that technology yet.

Answer 6

Cars are small and short compared to planes. It's possible to build a flying car, but think about it. Do you really want some guy cutting you off at 30000 feet? Also if you run out of gas, you aren't just inconvenienced, you're dead. Here's an article on HowStuffWorks about flying cars:

Answer 7

They already have, I've seen them in Popular Mechanics magazines, some were made decades ago. But then you run into new problems such as air traffic control, to prevent mid-air collisions, power lines, the constant up keep of the vehicle because when your car breaks down, you just pull over. Quite costly all this is.

Answer 8

If they used the same technology, then your average car would need about a 5,000 foot runway to get airborn. Anyways, why do you want to lift a car into the air, say a few thousand feet, and burn ll that fuel lifting it to get a gallon of milk 2 miles away ?

Answer 9

They can, however, it is still not cheap to mass produce planes. They can cost around $200,000 and up, and all the maintenance costs. Then, there's the infrastructure needed to support lots of planes - runways, fueling stations, air traffic control, etc., not to mention licensing. For most people, it's too much trouble.

Answer 10

They can do this to make a car fly. The problem is that it is much cheaper to go to the grocery store with four wheels instead of two wings and two propellers.
