Dude, Where’s My Jetpack?

Tuesday, March 10th, 2009

The public ate it up. This was the future they had been waiting for. Ever since Daedalus made those wax-and-feather wings we’ve been dreaming of something that would allow us to soar like birds.

The age old dream seemed one step closer to reality when Wendell Moore of Bell Aerosystems introduced a twin-jet hydrogen peroxide propulsion system mounted to a backpacks in the 1950s.

The Small Rocket Lift Device was a nifty piece of engineering. The U.S. Army showed interest in developing jetpacks (also known as rocket belts) to move infantry over difficult obstacles like mines and fly assault troops from ship to shore in amphibious operations.

That is until the Army soon discovered rocket belts were difficult to maneuver, ear-splittingly loud, and had a maximum of thirty seconds in flight. Funding dried up.

To this day, a number of jetpack enthusiasts are still working out the kinks. Here’s a good article on recent efforts that appeared in the Wall Street Journal. They point out, somewhat surprisingly, that less people have flown in untethered jetpacks than have walked on the Moon. A neat bit of trivia.

Also, check out this excellent YouTube video, ripped from the History Channel, with a thumbnail history of jetpacks.

Flying Cars

Friday, February 6th, 2009

Right after 9/11, I was interviewed by Fox News for a new story on flying cars. “Perish the thought of bin Laden in a Skycar,” I was quoted as saying (I do not remember saying this). My opinion on flying cars is not popular with devotees but I stand by the basic argument–is there any persuasive reason these two forms of transportation need to be merged when each technology works perfectly well on its own?

The latest flying car to get some media buzz is the Terrafugia Transition. It looks absolutely whiz-bang but I noticed it is being promoted as a sports aviation vehicle, a far cry from the futuristic fantasies of the past. Perhaps we’ve downsized our flying car dreams.

Here’s the original Retrofuture article I wrote back in 1999:

flyingcarLike so many other stories profiled in the Retro Future, the ConvAIRCAR flying car was a noble but doomed attempt to push the boundaries of what is possible.

On paper, the ConvAIRCAR was truly the stuff of commuters’ fantasies. It had “all the advantages of a Cadillac” according to its manufacturer. So what happened? The same thing that happens to all flying cars–the dream crashed and burned before it could take off…this time literally.

The ConvAIRCAR was not the first flying car to make it to the drawing board. That honor goes to the Curtiss Autoplane of 1917. But public interest in a car-plane hybrid didn’t take hold until after World War II. Airplane manufacturers, after the war, were shifting away from military aircraft to consumer production lines.convai4The Consolidated Vultee Aircraft Company of San Diego, California was one of those companies looking for a new outlet to sell their aircraft. Sensing the time was right for a flying car, they poured hundreds of thousands of dollars into developing a prototype built by aerodynamic engineer Theodore P. Hall.

Also lending a hand was Henry Dreyfuss, one of the outstanding industrial designers of the 20th century. Dreyfuss designed telephones for Bell, tractors for John Deere, thermostats for Honeywell, and cameras for Polaroid. But a flying car? What motivated the famously no-nonsense Dreyfuss–a devotee of Louis Sullivan’s dictum that “form follows function”–to lend his talents to such a far-fetched endeavor? The cynic would say money; but, in truth, a flying car didn’t seem that far-fetched at the time.

“The market for this flying automobile will be far greater than a conventional light plane,” Consolidated Vultee promised, “because the purchasers can obtain daily use from the car to get more out of his investment.” The estimated cost: $1,500. Flight attachments were an additional cost.
convai4bThese attachments were integral to the ConvAIRCAR’s design. After driving to the airport, an owner had to connect a flight unit (which included a propeller) to take off. At the next airport they simply removed the detachable wings and drove away in what was an otherwise ordinary car.

Well, not exactly ordinary. Thanks to a “plastic-impregnated” fiberglass body that weighed only 725 pounds, the ConvAIRCAR achieved an astounding 45 miles per gallon. And it looked great–the aerodynamic envelope of “the only automobile that flies” was a remarkable achievement, truly years ahead of its time.

On November 17, 1947, the New York Times announced the news: a prototype of the ConvAIRCAR had circled San Diego for one hour and 18 minutes. These trials confirmed the best hopes of Consolidate Vultee. But success was short-lived. A few days after the test flight, a pilot crash-landed the ConvAIRCAR in the desert (it was later discovered a gas gauge had accidentally been shut off) and the only prototype in existence was demolished beyond repair.

convai2Eventually another model of the ConvAIRCAR was built but the damage was done. The high cost of production and the limited market potential–not to mention the negative publicity–spelled doom (sadly no examples of the ConvAIRCAR survive; the second prototype perished in a fire at the San Diego Air & Space Museum).

The failure of the ConvAIRCAR was not unique. Dozens of inventors and aerodynamic engineers have tried to create similar vehicles in the last fifty years–none has successfully marketed a flying car. According to a 1989 article in Smithsonian, over 30 patents for flying cars have been filed this century in the United States alone; usually boasting fanciful names like Aerocar, Autoplane, Airphibian, and Skycar.

To this day several obstacles stand in the path of launching a successful flying car. First, the FAA is not likely to grant airspace to these vehicles–congestion in the air is bad enough. Secondly, flying cars, traditionally, have suffered from an engineering problem: as cars they are overpowered, as planes they are underpowered. And, last, the insurance is certain to be prohibitively expensive.

No, sadly, you will not be able to jump into a flying car for a quick trip flyingcar4to the 7-11 in the year 2000. But as long as “The Jetsons” is still running on the Cartoon Network, these dream machines will undoubtedly live on.

A Flying Car Is Announced (Again)

Friday, January 23rd, 2009

Nothing says Retrofuture more than the age-old dream of launching a flying car. The latest project to create a media buzz is being developed by former NASA engineers based in  Massachusetts.

The Terrafugia Transition (a mouthful of a name it is) uses a tank of everyday unleaded fuel and, thanks to its fold-up wings, fits neatly into a typical suburban garage.

To combine an airplane and a car has been the dream of engineers for almost a century. These Jetson-like fantasy vehicles present engineering issues as well as FAA airspace obstacles.  But if you’re a believer and you’re ready to buy into the dream this nifty looking  “roadable light sport aircraft” is yours for the nice round sum of $200,000.

Terrafugia claims that twenty have been pre-ordered already.  They hope to have the Transition out in 2010.

The Car of the Future Is Announced (Again)

Friday, January 23rd, 2009

Wow, a three-wheel all-electric car that gets 200 miles per gallon. Very Retrofuture-esque looking. According to Wired it has the inside track on winning the $10 million dollar Automotive X Prize.

I have uploaded my old Firebird III dream car piece from 1999 which features the work of the great designer Harley Earl. The so-called “Dream Car” has a long and hallowed place in our collective imagination. It looks like we’re getting closer to an environmental “Dream Car.” If the 2e (pictured above) is any indication it will look less like a flying Batmobile and more like the Ansari X Prize winner SpaceShipOne.
