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]
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.
Rocket mass heaters are developed from rocket stoves, a type of wood-burning stove, and masonry heaters. A primary design of a rocket mass heater consists of an insulated combustion chamber where fuel is burned with high efficiency at high temperature, and a large thermal mass in contact with the exhaust gases , which absorbs most of the ...
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 ...
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.
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 ...
In the full-flow rocket engine, the preburner exhaust is fed into a turbine and then into the main combustion chamber. Several variants of the staged combustion cycle exist. Preburners that burn a small portion of oxidizer with a full flow of fuel are called fuel-rich , while preburners that burn a small portion of fuel with a full flow of ...
A liquid apogee engine (LAE), or apogee engine, refers to a type of chemical rocket engine typically used as the main engine in a spacecraft. The name apogee engine derives from the type of manoeuvre for which the engine is typically used, i.e. an in-space delta-v change made at the apogee of an elliptical orbit in order to circularise it.
