Rockets and People<br />

great difficulty. Not only did they manage <strong>to</strong> get their people out, but they also<br />

saved the work they had done on an experimental engine with a thrust of<br />

500 kilograms.”<br />

Lyulka theoretically designed a gas-turbine engine (GTD) in 1938 at the<br />

Kharkov Aviation Institute.The first RD-1 engine was developed in Leningrad at<br />

the Kirov Fac<strong>to</strong>ry’s SKB-1, which Lyulka directed. Bench tests were <strong>to</strong> have begun<br />

in 1941, but the war and subsequent blockade of Leningrad had dashed their plans.<br />

Long before the war, Bolkhovitinov was interested in work being done on various<br />

designs of air-breathing jets (VRD). 2 He unders<strong>to</strong>od that the engine propeller<br />

unit of pis<strong>to</strong>n engines fundamentally limited flight speed and altitude. As soon as<br />

the opportunity presented itself, Bolkhovitinov had turned <strong>to</strong> Shakhurin with the<br />

request <strong>to</strong> evacuate Lyulka from Leningrad. Shakhurin arranged this with the<br />

Leningrad authorities and Lyulka and his surviving personnel were saved.<br />

In Bilimbay we led a semi-starved existence. However, we heard from Lyulka’s<br />

rescued Leningraders what real hunger was.They ate the brown bilimbaikha down<br />

<strong>to</strong> the last drop of the broth that we found barely edible.They did not drop a single<br />

crumb of bread.<br />

Lyulka’s workforce included several au<strong>to</strong>matic control specialists. Bolkhovitinov<br />

suggested transferring them <strong>to</strong> me. Lyulka agreed under the condition that I would<br />

develop equipment <strong>to</strong> regulate and control the turbojet engine. I spent three days<br />

learning the principles of the turbojet engine. Lyulka personally explained <strong>to</strong> me<br />

the difference between the two classes of reactive engines—liquid-propellant<br />

rocket engines and turbojet engines. He did not disparage liquid-propellant rocket<br />

engines, which had <strong>to</strong> carry their own fuel and oxidizer. But with gentle humor,<br />

alternating Russian speech with melodious Ukrainian, of which he had a beautiful<br />

command,Arkhip Lyulka proved that everything had its place while telling me<br />

about the turbojet engine.<br />

The air-breathing turbojet engine uses the oxygen of the air that enters through<br />

the aircraft’s air intake from the atmosphere.The air is compressed by a compressor<br />

and then passes through combustion chambers where gasoline, or better still<br />

kerosene, is injected. The gas formed during combustion passes through the<br />

turbine, turning the compressor, and is ejected through the nozzle.This is not the<br />

dazzling bright flame of the liquid-propellant rocket engine, but hot gas that has<br />

already been depleted in the turbine and which is almost invisible in the daylight.<br />

Once I had become familiar with the principles of turbojet engines and the<br />

ideas for regulating them, I came <strong>to</strong> the conclusion that the immediate problems<br />

related <strong>to</strong> the au<strong>to</strong>matic regulation of the turbojet engine needed <strong>to</strong> be solved<br />

without any electrical devices, at least for the time being. I thought that we should<br />

instead use the capabilities of purely mechanical and pneumohydraulic au<strong>to</strong>mated<br />

2. VRD—Vozdushno-reaktivniy dvigatel (Air-Reactive Engine). In Western technical vernacular, these types<br />

of engines are known as ‘air-breathing jet engines’ or simply ‘jet engines.’<br />
