Earlier jet engines like the the Pratt & Whitney JT8D used on the B727, B737, DC-9, etc. produced thrust in the 12,000 to 18,000 pound range. (A pound of thrust is equal to a force needed to accelerate 1 pound 32 feet per second per second.) Newer jet engines like the Rolls Royce and GE engines used on the B787, A380, etc., are capable of producing thrust in the the 65,000 to 80,000 pound plus range.
What else can I help you with?
Why were jet engines better than propeller driven engines?
Jet powered aircraft have a number of advantages over conventional internal combustion propeller driven aircraft. To start with, jet engines can operate in a much wider range of conditions. Propellers lose their effectiveness at high altitudes and at high speeds while jet engines are capable of operating at much higher altitudes and a much much higher speeds with little or no loss of power. Jet engines have fewer moving parts than internal combustion engines which makes them easier and simpler to design, build, maintain and repair. Jet engines run on fuel that is very similar to diesel fuel, and is much safer to handle and store than gasoline. Jet engines can produce much more thrust power for their weight than conventional reciprocating engines do.
How much do jet engines cost?
It depends on the power of the jet engines. The normal cost would be atleast 1 million dollars for a reasonably good power engine. There are also engines less than that cost.
What is the term for powering airplane engines?
Jet engines produce thrust. All others produce horsepower.
How many countries can produce jet engine?
I would estimate 21- 25 countries can and do produce jet engines
What is the speed of a jet engine?
Jet engines can vary in speed depending on the type and size of the engine. Commercial jet engines typically operate at speeds between 9,000 and 25,000 rpm (revolutions per minute). Military jet engines can reach even higher speeds, often exceeding 30,000 rpm.
How loud are jet engines?
Jet engines produce a variety of incredibly loud sounds. These sounds can potentially make you go deaf if you are too close.
What is the engine power of jet engine?
Please redefine your question, what exactly do you want t know? Jet engines can produce power in a multitude of ways, either thrust delivered through exhaust gasses in Newtons per square Meter, of they can deliver power through the shaft in the jet engine which would deliver a torque power. (Most modern jet engines utilized in aircraft by the way produce both, thrust for the propulsion of the aircraft and torque to power all accessory devices such as fuel pumps, oil pumps and hydraulic pumps.
Type of engine used to power space flights?
rocket engines,compared to jet engines
How many horsepower does a jet engine on a have?
Jet engines are typically measured in thrust rather than horsepower, but if converted, they can produce a significant amount of power. For example, a commercial jet engine can generate between 20,000 to 100,000 pounds of thrust, which translates to roughly 26,000 to 130,000 horsepower. Military jet engines can produce even higher figures, with some engines exceeding 30,000 pounds of thrust, equivalent to over 40,000 horsepower. However, the exact horsepower varies depending on the specific engine model and its design.
What would jet engines be like without Chromium?
Pretty much the same. Most jet engines contain very little chromium
How many engines does a jumbo jet have?
A jumbo jet, also known as a 747, has four engines. These engines are all mounted on the wings of the plane and are needed to power the plane through height weight takeoffs.
What is Rolls Royce?
Rolls Royce is an engineering firm which produce products such as jet engines for boats and planes amongst other things.
