You take a nozzle and you create 10 random variations on the nozzle.

How do you design that nozzle?

And after 45 generations, you have this incredible nozzle.

You pump it at a high pressure through a nozzle.

And he will, or she will, calculate the optimal design of the nozzle.

A motor nozzle exit cone extension will increase the vacuum specific impulse of the motor.

Efforts began to transition Redesigned Solid Rocket Motor nozzle production from Utah to the former Advanced Solid Rocket Motor site in northeast Mississippi.

In order to supplement the thrust of the first stage, two SRBs with a thrust of 160 tonnes each are installed. Thrust direction control of the SRBs is performed through a movable nozzle.

Light water reactors (LWRs) like those at Fukushima, which use water as a primary coolant, produce most of the world s nuclear power. The huge quantities of local water that LWRs consume for their operations become hot water outflows, which are pumped back into rivers, lakes, and oceans.

SINGAPORE Japan s nuclear crisis is a nightmare, but it is not an anomaly. In fact, it is only the latest in a long line of nuclear accidents involving meltdowns, explosions, fires, and loss of coolant accidents that have occurred during both normal operation and emergency conditions, such as droughts and earthquakes.

One notable example right before the launch, SpaceX engineers found a few cracks in the second stage engine nozzle extension. Rather than haul the spacecraft back to the shop for repairs, they simply analyzed the flaw, trimmed off the affected section, and proceeded with the launch.

For the Fukushima nuclear power plant, a 1,000 year flood and ordinarily innocuous design defects combined to deprive the reactors of circulating water coolant and cause serious radiation leaks. In financial markets, an unexpected collapse in real estate securities and design defects in the derivatives and repo markets combined to damage core financial institutions ability make good on their payment obligations.
