Diagram of a MMRTG. The multi-mission radioisotope thermoelectric generator (MMRTG) is a type of radioisotope thermoelectric generator (RTG) developed for NASA space missions [1] such as the Mars Science Laboratory (MSL), under the jurisdiction of the United States Department of Energy's Office of Space and Defense Power Systems within the Office of Nuclear Energy.
A small manufactured rocket cooking stove A rocket stove Rocket stove illustration. A rocket stove is an efficient and hot burning stove using small-diameter wood fuel. [1] Fuel is burned in a simple combustion chamber containing an insulated vertical chimney, which ensures almost complete combustion prior to the flames reaching the cooking surface.
The rocket mass heater has two very important features the rocket stove does not have. One is the drum, which provides a downdraft that increases the power of the draft and makes it possible to run the remainder of the flue horizontally. The other is a horizontal flue system that captures the heat of the stove in a thermal mass.
Ernie and Erica Wisner are a couple from Tonasket, Washington, United States, best known for their innovative rocket mass heater designs. They are often referred to as the worldwide leaders and trainers in rocket stove technology. They have made over 700 rocket stoves all over the world. [1]
If you want to live there as humans, you will have to grow your own crops at the site," said study co-author Wieger Wamelink, a plant ecologist at Wageningen and CEO of a company called B.A.S.E ...
After being run through a turbine to power the pumps, the gas is injected into the combustion chamber and burned with the remaining oxidizer. The staged combustion cycle (sometimes known as topping cycle , preburner cycle , or closed cycle ) is a power cycle of a bipropellant rocket engine .
The pulse rocket motor allows the motor to be burned in segments (or pulses) that burn until completion of that segment. The next segment can be ignited on command by either an onboard algorithm or in a pre-planned sequence. All of the segments are contained in a single rocket motor case, as opposed to staged rocket motors. [1]
The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...
