Working principle of rocket engine?
A rocket engine, or simply "rocket," is a jet engine[1] that uses only propellant mass for forming its high speed propulsive jet. Rocket engines are reaction engines and obtain thrust in accordance with Newton's third law. Since they need no external material to form their jet, rocket engines can be used for spacecraft propulsion as well as terrestrial uses, such as missiles. Most rocket engines are internal combustion engines, although non combusting forms also exist.Rocket engines as a group, have the highest exhaust velocities, are by far the lightest, and are the most energy efficient (at least at very high speed) of all types of jet engines. However, for the thrust they give, due to the high exhaust velocity and relatively low specific energy of rocket propellant, they consume propellant very rapidly.
What is jp7?
'JP-7', where JP stands for 'Jet Propellant' is a jet fuel for the use in supersonic aircraft because of its high flash and thermal stability. For example in SR-71,because of the high temp. environment in which the engine operates, it uses low volatile JP 7 jet fuel which requires a chemical ignition system.
What is hunting in steam turbines?
When the steam turbine can not maintain its selected or designed speed.Type your answer here... Speed fluctuating from low to high speed continously.
What does a turboprop do?
Answer:The combination of the words turbine and propeller in techno jargon will give you the word "turboprop". A turboprop engine is a turbojet (gas turbine) engine, which powers the propeller/s. A conventional jet engine produces its thrust in large part due to the heated gasses escaping out the rear of the engine. While this is very useful for aircraft which fly at high speeds and high altitudes, it is less desirable for aircraft which are designed to fly at slower speeds and take off from smaller runways.A turboprop engine is a jet engine which converts the bulk of its thrust into rotational energy for powering a propeller. This allows jet engines, which are a high-rpm low-torque engine to be used in situations where low-rpm and high-torque are needed instead.The higher reliability and efficiency of a jet or turboprop engine as compared to an internal combustion engine makes them very desirable for aircraft designs which, in the past, would have utilized internal combustion engines.Answer 2A turboprop is a jet engine with a propellor attached - a jet engine is a turbine (fan) that compresses a large volume of air for combustion in a chamber as a opposed to a piston - a turbo charger on steroids - the propellor is attached to the central shaft of the fan blades - the two exhaust tubes on either side of the front of the turboprop are for the jet exhaust and it actually can add to the speed of the aircraft - the jet engine is usually backwards on a turboprop, the air intake under the engine is sent to the back which is really the front of the jet turbine, compressed by the fan blades (which drive the propellor) then sent to the combustion chamber where it is mixed with fuel and ignited - then exits through the exhaust tubes which bend to point backwards adding to the total thrust of the engine Often the word turboprop is confused with turbo charged which is a regular piston engine that uses a turbo charger (air compressor) - the P-38 lightning twin boom fighter of WW2 is a great example of a turbocharged engine and once you hear the sound the turbo chargers make you never forget itTurbo prop engines address a need for a compromise between propellor and jet engines - propellors are efficient at slow speeds to about 350 mph (meaning the amount of fuel used for speed and range) and dont have as much power as a jet - jets are effecient from about 300mph up and are more powerful than a piston engine but use more fuel - a turbo prop has nearly the power of a jet without as much fuel use and fills the gap for a mid range speed of about 200 to 400 mph - rarely see turboprops on low speed aircraft because of the extra fuel use with exception of some STOL bush style aircraft like the cessna caravan and the new quest kodiak that need the extra power for short/rough field useAlso turbo props can reverse thrust like a jet engine but do so usually by changing the angle of the propellor blades - another big advantage over piston engines for short runways - also turboprops use jet fuel since they are jet engines so they are being used more frequently in countries outside USA where avgas is becoming hard to find (not much general aviation aircraft but lots of jet airliners in many countries)A big advantage to using turboprops is how long they can be flown before a complete overhaul - the time can vary a lot by engine but an average time for a piston engine is about 1800 to 2000 hours and a turbo prop about 3000 to 3600 hours - so you can fly a turboprop a whole lot longer between major overhauls.
Can a plasma jet carry a person through the air?
A plasma jet is not a conveyance (like a passenger jet airplane). It is a superheated stream of ionized gas, and is used in several applications including - surgical vaporization and cautery - cutting and shaping conductive metals - high performance spark plug systems - spacecraft thrusters (Plasma jet engines would not function well in a planetary atmosphere because they are designed for high specific impulse but low total thrust.)
If A large jet flying overhead is low enough so that a man on the ground can hear its engines. The man sees the jet before he hears the engines because?
The speed of light is faster than the speed of sound
What is the speed of an F-16 fighter jet?
An F-16's maximum speed "at sea level" (Flying low) is Mach 1.2 (915 mph - 1.470 km/h). An F-16's maximum speed "at altitude" (Flying high) is Mach 2.0 (1.500 mph - 2.400 km/h). Most fighter jets usually fly just below Mach 1 when cruising (Cruising speed) to save fuel. Going very fast costs a lot of fuel.
How are the airfoils of a stunt plane and fighter jet different?
The airfoils on a stuntplane are meant to make it extremely manueverable at low speed, so the control surfaces are much larger. Jet fighters need less movement.
Why are fighter jet planes flying so low just above our house and is it safe and legal?
Low flying of jet planes is not permitted over domestic areas. The sound waves are likely to cause damage to loose glass panes besides injurious to cardiac patients. If it crosses sound barrier, the sonic waves will cause severe vibrations and also effects cardiac function.
Why you see smoke of high flying airplanes?
That line of smoke is called a vapor trail. You can still see it on low flying planes, but it must be a jet plane.
Do fighter jets have transmission?
Not a transmission as you know it to change the speed of the vehicle. But every jet engine has a kind of transmission called a CSD that is like a PTO on a farm vehicle. In the CSD, engine speed is altered to drive the fuel, oil and hydraulic pumps and to perform similar low output tasks.
A jet plane traveling at a speed of 82 miles per hour is traveling at what speed in meters per second?
Apart from the fact that a jet plane would stall at that low a speed, the speed is equivalent to 36.657 metres per sec
Can a low flying jet break glass?
yes. the plane is thicker than glass.it would still shatter the glass
Can a court take judicial notice that a sonic boom caused by a jet aircraft flying at low altitude was an explosion?
Yes, because to someone who does not know about the speed of sound or doesnt expect it, a sonic boom sounds just like an explosion.
Is the B-2 Spirit a jet?
Yes. The B-2 is a US Air Force bomber that is powered by jet engines and is a flying wing with a low radar cross section---i.e. a stealth bomber.
What makes a carb run rich?
it has to do with the high speed and low/idle jets and how they are set or maybe the float is to unbalanced and need adjustment if the jet are permanently set, the jets are turned in a certain amount to adjust how much fuel goes through this hole the jet regulates . so if you turn a jet way out it will run wayyy rich and turn it in to far it runs "lean" which can be bad for a motor if run to long , so u need the high speed low speed jet setting if that is the case otherwize it most likely the float.
What are the kinds of low flying birds?
Chickens can fly , but they are low flying birds.
