The German aeroplane engine trials were held a year later, and sixty-six engines entered the competition, fourteen of these being made with air-cooled cylinders. All of the ten engines that were chosen for the final trials were of the water-cooled type, and the first place was won by a Benz four-cylinder vertical engine which developed 102 brake horse-power at 1,288 revolutions per minute.
There were also two large propellers, one in front and the other at the rear. These were carefully made, of different layers of wood "built up" as they are called, to make them stronger. They were eight feet in diameter, and driven by a twenty-cylinder, air-cooled, motor, whirled around at the rate of fifteen hundred revolutions a minute.
Even in that air-cooled room their generally unwashed condition was noticeable. Hanlon knew instinctively he would make no friends among them. "I only hope I make no enemies. Why was I, so drastically different from them, chosen as a guard? What's that leader got in his devious mind, anyway?" There were four mining engineers, and these men were keen, alert fellows.
Swift had improved very much in the past few days, and though Dr. Gladby said he was far from being well, the physician declared there was no reason why he should not do some inventive work. He and Tom were deep in an argument of gasoline motors, discussing the best manner of attaching the fins to the cylinders to make them air-cooled, when a voice sounded outside, the voice of Eradicate: "Heah!
Though some expert had recommended the French motor, Ned had preferred to use one made in America, not only because he had been able to get it quicker but because he believed it as good as the foreign make. The engine had eight air-cooled cylinders, in two sets of four, placed at an angle of ninety degrees to each other.
The original machine was air-cooled or to be more accurate, the motor simply was not cooled at all. I found that on a run of an hour or more the motor heated up, and so I very shortly put a water jacket around the cylinders and piped it to a tank in the rear of the car over the cylinders. Nearly all of these various features had been planned in advance. That is the way I have always worked.
For the moment Lea had forgotten herself in taking care of him. He put some of the antiseptic on her scalp bruise and she squeaked, pulling back. They both swallowed the pills. "That sun is hot already," Lea said, peeling off her heavy clothing. "Let's find a nice cool cave or an air-cooled saloon to crawl into for the day." "I don't think there are any here. Just sand. We have to walk "
We crossed the Pauma Creek, and some distance beyond it we left the river to our right, turned sharply to the left, and ran up to the base of Smith's, or Palomar Mountain. Then came the grade up the mountain. If you are not stout-hearted, and haven't a powerful machine, avoid this beautiful drive. If you are not driving an air-cooled car, carry extra water with you.
The motor in his cross-Channel monoplane was an experimental one of low power, air-cooled, and prone to over-heat and lose power after only a short period of running. To cross the Channel, even under the most favourable circumstances, he knew this engine must run without breakdown for thirty-five or forty minutes. This it had not done at any rate in the air before.
His cross-Channel monoplane was a single-seated craft fitted with an air-cooled motor of about 25 h.p. The machine I agreed to buy at Rheims, and which was known as Bleriot No. XII., would carry two people, pilot and passenger, while it had an 8-cylinder water-cooled motor developing 60 h.p. an exceptional power in those days.
