Rutherford is named after renowned New Zealand-born scientist Ernest Rutherford.It is a small liquid-propellant rocket engine designed to be simple and cheap to produce. It is used as both a first-stage and a second-stage engine, which simplifies logistics and improves economies of scale.
The design is similar to the older RTA96C engine, but with common rail technology (in place of traditional camshaft, chain gear, fuel pump and hydraulic actuator systems). This provides maximum performance at lower revolutions per minute (rpm), reduces fuel consumption and emits lower levels of harmful emissions.
Belliss and Morcom developed a two-cylinder engine of 20 bhp at 625 rpm that used a small separate oil pump to feed oil under pressure to the crank bearings, through long drilled holes in the crankshaft.
Generally, axial pumps tend to give much lower pressures than centrifugal pumps, and a few bars is not uncommon. Their advantage is a much higher volumetric flowrate. For this reason they are common for pumping liquid hydrogen in rocket engines, because of its much lower density than other propellants which usually use centrifugal pump designs.
Fuel primer pump - A manual pump to add a small amount of fuel at the cylinder intakes to assist in starting a cold engine. Fuel-injected engines do not have this control. For fuel-injected engines, a fuel boost pump is used to prime the engine prior to start. Fuel quantity gauge - Indicates the amount of fuel remaining in the identified tank ...
Here's how we compiled the list: We pored through 30-year average snowfall statistics of hundreds of locations in the U.S. from 1991 through 2020. We considered only those towns and cities with a ...
The Garrett TFE731 (now Honeywell TFE731) is a family of geared turbofan engines commonly used on business jet aircraft. Garrett AiResearch originally designed and built the engine, which due to mergers was later produced by AlliedSignal and now Honeywell Aerospace.
