The Wonderful Machine Age – The Autogyro

Technology has been one of the hallmarks setting humans apart from other life forms on this planet. From the primitive flint hand axe to the satellites we don’t even think about that make modern worldwide communication possible, humans have used technology to make up for our physical limitations and to improve where we live and how we live.

Ever since we saw a bird fly, we’ve wanted to do likewise. We dreamed of flight and put it in our myths. We flew in stories long before any human achieved liftoff. Kites and balloons were our baby steps. Then the airship ruled our imaginations. On the eve of World War II fixed-wing, heavier-than-air passenger aircraft crossed the Atlantic. Even if the Hindenburg had not burned, the airship had been rendered obsolete by the Boeing 314 Clipper flying boat in 1939.

The Second World War saw the perfection of the helicopter, the building of the long-range heavy bomber, and the invention of the jet, as well as the invention of the long-range ballistic missile. Suddenly, in 1945, such things as balloons, blimps, and rigid airships seemed nothing more than relics of the past.

The balloon has been relegated to hot-air sightseeing excursions, for the most part. The blimp has been reduced to a novel sightseeing experience or eye-catching advertising. There continues to be talk of lighter-than-air heavy lifters for long-distance cargo hauling, but they continue to remain the stuff of dreams.

However, one of the dinosaurs is making a true comeback. Namely, the autogyro. An autogyro? What’s that? At the risk of oversimplifying, it’s an airplane that uses an unpowered rotor instead of wings to achieve lift.

Juan de la Cierva wanted an airplane that could fly safely at low speed. To accomplish his desire, he invented the autogyro. The first successful flight was on 9 January 1923 in Madrid. Below is a picture of the first Cierva autogyro.

Cierva got his wish. Sustained, lazy low speed flight is what the autogyro excels at. It can’t hover like a helicopter because the rotor is not powered. The rotor relies on the forward movement of the plane to make it spin and provide lift. Despite its inability to hover, the autogyro has a distinct advantage over the helicopter: cost. They are cheaper to buy and cheaper to operate. They also have a big advantage over airplanes in that they need very little runway to take off and virtually none to land. An autogyro can be in the air using no more than 30 to 200 feet of runway. An autogyro can’t stall, like a plane, and doesn’t end up in a tailspin. Cierva was certainly on to something.

Below is a later Cierva autogyro:

So why didn’t the autogyro take off? A couple reasons. Cierva was the main proponent of the autogyro. After all it was his baby. His death in a plane crash in 1936 was a major blow to those promoting the autogyro. The second reason was the helicopter. The principle of the helicopter (which the autogyro also uses) goes back to 400 BC and the Chinese toys that probably most of us played with as kids.

The first successful helicopter, the Bréguet-Dorand Gyroplane Laboratoire, built in 1933, took its first successful flight in 1935. In 1936 and 1937, the Focke-Wulf Fw61 was setting world record after world record and the world forgot Cierva and his autogyro.

Below are pictures of early British autogyros, which were soon eclipsed by the helicopter.

A good idea tends to stick around and the autogyro is a very good idea. The late ‘70s and early ‘80s saw the birth of the ultralight aviation movement. People wanted more than just hang-gliding. They wanted to fly and they wanted their desire to be affordable. Enter the autogyro, or the gyrocopter as it is often called today. Aside from personal use, many cash-strapped law enforcement departments are turning to the autogyro because it is a cheaper alternative than the helicopter. The autogyro’s ability to stay in the air at very low speed makes it a viable alternative to the helicopter for crowd control, traffic control, and city surveillance. And because today’s autogyro is small, it can easily go where planes and helicopters can’t. Versatility is always a plus.

Here are some modern autogyros. Aren’t they beautiful?

Once again an old idea, which some thought obsolete and dead, has made a comeback — thanks to modern technology, brought about by the wonderful machine age.

These autogyros are so cool, I think I’m going to get me one. They have to be better than bucking traffic on a clogged freeway. And weren’t we supposed to have flying cars by now anyway?

The Wonderful Machine Age – His Master’s Voice

Who isn’t familiar with the picture of the dog focused on the phonograph horn listening to the voice of his deceased master? Such is the power of sound, especially familiar sounds.

While typing this post, I was listening to the incredibly beautiful work of music by Ralph Vaughan Williams, entitled “The Solent”. Prior to 1877 such would not have been possible. For in that year, Thomas Edison invented the phonograph and within decades home entertainment was revolutionized. The piano in the parlor began to collect dust and piano lessons began to become a thing of the past.

Edison’s machine used a needle to record little hills and valleys in a wax cylinder, which when played back produced sound. In 1887, Emile Berliner patented the gramophone which used a flat disc. The needle followed a track with moved side to side instead of up and down.

Below is Edison’s phonograph from 1899.

Eventually Berliner’s gramophone won the commercial battle because the process of producing records instead of cylinders was cheaper. A record cost 20¢, whereas a cylinder cost 50¢. For the cost of 2 cylinders, I could buy 5 records. Pretty simple math and the cylinder became a footnote in history. Ironically enough, Edison had already contemplated the disc but favored the cylinder because it was scientifically more perfect. I guess even geniuses make mistakes. And that’s why many of us grew up collecting records instead of cylinders.

Edison’s phonograph was the first machine to both record and playback sound. However, an earlier machine, the phonautograph, invented in 1857, made a visual image of the voice for study by doctors and scientists. The image could not be played back. At least not until 2008 when, with the help of optical scanning and computers, the pictures were turned into digital audio files and listened to for the first time. The oldest recordings of the human voice.

Just as Bell had competition for the telephone, so did Edison with the phonograph. That competition came in the form of Charles Cros’ paleophone. Cros, who was a poet and amateur inventor, came up with the idea to use photoengraving to transfer the phonautograph image to a disc or cylinder for playback. He wrote a letter describing his idea and deposited it with the French Academy of Science on 30 April 1877. Cros’ idea became public on 10 October 1877, however by then he had improved upon his original concept by inventing a way to capture and record sound using an acid-etch method.

Learning of Edison’s machine, Cros had his April letter opened and claimed scientific priority over Edison.

Cros’ method became standard procedure to produce the metal masters from which the flat records could be pressed. Unfortunately, he died in 1888 and could not enjoy his triumph over Edison. Today, no one’s even acquainted with the name of Charles Cros.

The phonograph, or gramophone, is perhaps one of the most iconic inventions of The Machine Age. Rivaled only by the telephone and the automobile. It appeared at the age’s beginning and was going strong when the age faded away. Today, the phonograph has morphed into the ubiquitous iPod.

There was a gramophone on board the Graf Zeppelin on its round the world flight in August 1929. Brought on board by millionaire Bill Leeds, Commander Hugo Eckener had it promptly removed. Leeds retrieved the machine and told Eckener if weight was the problem he’d leave behind his luggage.

Bram Stoker, in his novel Dracula, had Doctor Seward record his diary on a phonograph. Seward, however, was worried the count might be able to melt the wax cylinders with his mysterious powers and destroy Seward’s recordings of the vampire’s machinations. That is perhaps the first literary example of the dictaphone, which has also gone digital.

Of equal lineage with the phonograph is the tape recorder. We don’t really use them anymore but we do use digital versions to record our voices.

The tape recorder was invented in 1886 by Alexander Graham Bell’s Volta Laboratory. The machine used a strip of paper coated with beeswax. Magnetic recording was first conceived of in 1877 and demonstrated in 1898, first using wire and later tape.

Below is an early magnetic wire recorder from 1898.

The record player and tape recorder were everywhere in the 20th century — even more widespread than the TV. I think retro-futurist writers with a little imagination can easily come up with something true to form and yet truly fantastic. Bram Stoker did so simply by including a phonograph in his novel. Now what if that record player or tape recorder could fit inside a small brown box about the size of a deck of cards?
