21. At the rear of the rocket is an elongated exhaust nozzle , attached to which are eight forward folding fins. 22. Some is used for cooling the rear exhaust nozzle , known as the 3-bearing swivel duct nozzle ( 3BSD ). 23. The unit sent the wrong signals to the rocket's movable exhaust nozzles , changing their angles and tilting the rocket's trajectory. 24. Besides the ducted rocket, four rockets were positioned at the exhaust nozzle , along with the 19XB turbojet produced by Westinghouse. 25. The YJ93 was a single-shaft axial-flow turbojet with a variable-stator compressor and a fully variable convergent / divergent exhaust nozzle . 26. Similar devices are being used to give fighter planes greater maneuverability by changing the direction of their engine exhaust nozzles . 27. In order to achieve the required Mach 2 performance at high altitudes, the exhaust nozzles and air intake ramps were variable. 28. Essentially, they pulsed several beams of laser light across the exhaust nozzle of a model engine for nine-billionths of a second. 29. Furthermore, he tackled the problem of air flow through the introduction pipe and exhaustion of combustion gases through a jet exhaust nozzle . 30. The first prototype "'004A "', which was constructed to run on diesel fuel, was first tested in October 1940, though without an exhaust nozzle .
