Flying Cars !! How Will it Work ?

Sitting amidst a sea of cars in bumper-to-bumper traffic on an endless expressway, have you ever daydreamed about your car taking off and flying over the road? Imagine if you could just flip a switch and unshackle yourself from the asphalt!

Traffic jams are the bane of any commuter. Many of us spend an hour or so stuck in traffic every week. The growing population is partly to blame for our congested roads, but the main problem is that we are not expanding our transportation systems fast enough to meet ever increasing demands.

One solution is to create a new type of transportation that doesn't rely on roads, which could one day make traffic jams a 20th century relic. To do this, we must look to the sky.

EARLY EXPERIMENTS

Glenn Curtiss, the Wrights' chief rival, was the first to design a flying car. The first flying car to actually fly was built by Waterman. Waterman became associated with Curtiss while Curtiss was pioneering naval aviation at North Island on San Diego Bay in the 1910s. However, it wasn't until March 21, 1937 that Waterman's Aerobile first took to the air.

The Aerobile was a development of Waterman's tailless aircraft, the Whatsit. It had a wingspan of 38 feet (11 m) and a length of 20 feet 6 inches (6.25 m). On the ground and in the air it was powered by a Studebaker engine. It could fly at 112 mph (180 km/h) and drive at 56 mph (90 km/h).

In 1926, Henry Ford displayed an experimental single-seat aeroplane that he called the "sky flivver". The project was abandoned two years later when a test flight crashed, killing the pilot.

There are nearly 80 patents on file at the United States Patent and Trademark Office for various kinds of flying cars. Some of these have actually flown. Most have not. And all have come up short of reaching the goal of the mass-produced flying car.

MODERN FLYING CARS

There is no lack of engineers taking on the challenge to design a new breed of flying cars. While sleeker, more advanced cars have been developed in the last decade, no one has come close to opening up a flying car dealership. Here are a few of the individuals attempting to deliver a flying car:

Paul Moller has spent 40 years and millions of dollars developing his Skycar. He is now very close to developing the first mass-marketed flying car. In 1965, he demonstrated his first attempt, the XM-2, which hovered off the ground but didn't go anywhere. In 1989, Moller unveiled the M200X, which has now flown 200 flights and can go as high as 50 feet (15.24 meters).

MACRO Industries in Huntsville, Ala., is developing a flying car that it's calling the SkyRider X2R. This aero car will be able to take off and land vertically. SkyRider incorporates the interior design of a 2-seat sports car with the mobility of a helicopter or airplane. The company said it is also developing 5 and 7-seat models of the SkyRider, and it should fit in most two-car garages. The navigation system will be controlled almost entirely by GPS satellites and cellular services.

In Israel, Dr. Rafi Yoeli of Urban Aeronautics is testing the CityHawk, a prototype of a fly-by-wire car. He's also working on a project centered around the X-Hawk, a rotorless Verticle-Take-Off and Landing vehicle (VTOL). Visit this Web site for more information.

In 1990, Kenneth Wernicke formed Sky Technologies to develop a small-winged flying car. His Aircar has flown at 200 to 400 mph (322 to 644 kph) and driven at 65 mph (105 kph). It's also small enough to fit into an average parking space.

Recently, Branko Sarh, a senior engineer at McDonnell Douglas Aerospace, has attempted to develop a flying car, called the Sokol A400, or Advanced Flying Automobile. Sarh designed a 4-passenger vehicle that would pop out telescoping wings at the push of a button.

SKYCAR

Moller's latest design, the Skycar M400, is designed to take off and land vertically, like a Harrier Jet, in small spaces. It can reach speeds of 400 mph (644 kph), but will cruise at around 350 mph (563 kph), and it has a range of 900 miles (1449 km).





Gasoline, diesel, alcohol, kerosene and propane can be used to fuel the Skycar, and its fuel mileage will be comparable to that of a medium-sized car, getting 20 miles (32.2 km) to the gallon. The initial cost of a Skycar will be about $1 million, but once it begins to be mass produced that price could come down to as low as $60,000.

The four-seat Skycar is powered by eight rotary engines that are housed inside four metal housings, called nacelles, on the side of the vehicle. There are two engines in each nacelle so that if one of the engines in one of the nacelle fails, the other engine can sustain flight. The engines lift the craft with 720 horsepower, and then thrust the craft forward.

SUMMARY

The mass availability of flying cars could be very exciting or very scary, depending on how you look at it. If proper safeguards are put in place, they could be the answer to our ever-worsening traffic jams. Flying cars that can travel at hundreds of miles per hour would not only cut that rush hour commute to a few minutes, but it would allow us to live hundreds of miles farther from work and still make it to the office faster than by road-bound cars today.
