Does anyone no how slow an aeroplane can fly at before the engines stall

Question

i was on plane the other day just about to land and we were slowing down and i just wondered how slow it could go and also what is the fastest an aeroplane can go?

Answer 1

that depends on all sorts of things.. drag, lift ,plane, size,wind rain , wing size, mono wing, twin engine.... etc.. to guess would sound kind of stupid.. how big is the plane ?  prop or jet.,turbo prop, or ?  most small planes like little cessnas can nearly "float" with the right conditions.  since i dont know what kind of plane you're talking about , i would say for small commuter like a cessna 2 passenger,  40 mph if you were to push its limits.... you also dont feel wind speed in a plane like you would in a car.. it feels real slow but in fact you're "flying" no pun intended...

Answer 2

It isn't engine stall it is wing stall... The engine runs at an idle on the ground and that is 0 mph... The wing however, can stall... In this the number will be an equation and it will depend on a balance between lift and weight... When the wing moves too slow to generate the lift needed the plane will fall as if someone holding it up just let go...

All wings are made in the shape of an airfoil... The top of the wing is more humped than the bottom... As the air passes over the top and bottom it travels further over the top than over the bottom... When it does this causes a vacuum... That is the lift generated by the wing... The faster air moves over it the more lift it makes... When the lift exceeds the weight of the plane it will fly...

All planes are different and everyone has a stall speed... Adding passengers is equal to raising the weight and therefore will raise the stall speed...

The fastest plane was the x15 and it went 4,519 mph in 1967... The space shuttle goes upwards of 17,000 mph for lower orbit flights... The Saturn V moon shots went upwards of 25,000 mph...

Answer 3

engines can stall (from lack of gas or whatever else). But the kind of stall you're looking for its a wing stall. That's when not enough air is flowing across the wing to produce enough lift to keep the airplane in the air. Stall speed is determined by airflow over the wings, weight, and weather.

A small aircraft, like a Cessna 172, will stall at 33 knots in landing configuration.

Large commercial aircraft in landing configuration will stall at approx. 120-130 knots depending on weight.

1 knot = 1.15078 MPH

Speed does not determine whether the engines run or stop.

The fastest true airplane, the SR71 flies at 80,000 feet and can go at Mach 3.2 but it has gone faster

Mach 3.2=2438.4 mph over ground

There was the MiG 25 also a true airplane went at Mach 3.6 but its engines were ruined afterward.

The X-15 is a rocket powered, air-launched manned rocketcraft that flew at Mach 6.85 or 4,519 mph.

The space shuttle's speed in orbit is 17,580 miles but it isn't in the atmosphere as defined by the FAI. However upon re-entry, the Space Shuttle reaches Mach 25.

A commercial airliner will cruise at around 35,000 feet around Mach 0.8 or less which is 609.6 mph over ground. A commercial airliner's max speed will be near it's cruise speed: Mach 0.86 to 0.90.

Actual ground speed will vary depending on winds

Answer 4

The engines of aircraft never stall in the way automobile engines stall, for all practical purposes.  Jet engines, in particular, tend to keep turning no matter what, although both jet engines and piston engines can stop working properly in various ways under various conditions.

There is another type of stall, called an aerodynamic stall, that occurs in airplanes under very specific conditions, but it has nothing to do with the engines.

The highest and lowest speeds of an aircraft depend on the aircraft type, its overall weight (with fuel, passengers, etc.), weather conditions, and other factors.  Jet airliners can fly as fast as 600 mph or so, and as slow as about 140 mph.  Small aircraft with propellers can fly at speeds of up to 240 mph or so (but usually much slower, around 160 mph tops), and as slow as just 45 mph or so.

Answer 5

The above are correct, but the word "stall" can be confusing.  Here's the simplified version...

>> Wings stall because there is insufficient airflow over them to produce lift.

>> [Jet] Engines "stall" similarly because the airflow around their blades (wings) becomes disturbed – aerodynamic stall just like the wings.  This has nothing to do with the speed of the aircraft.  Disturbed engine airflow my result from inlet problems/performance, blade damage, design flaws, and/or aggravated by foreign object ingestion/damage.  Ensuing pressure build-ups can only escape coming forward through the engine – none of which are related to the airspeed of the aircraft.  Normally, an aircraft's jet engines are operating at all power settings sitting perfectly still on the ground, are they not?
