Why can’t airplanes fly in space?

The bottom line is that airplanes can’t fly in space because there is no air in space. Airplanes rely on air to produce both lift and propulsion. Since there isn’t any air in space, airplanes must stay within the Earth’s atmosphere.

What would happen if an airplane flew into space?

Engine would flame out and there would be no thrust. Lack of air would make flight controls useless (elevators, ailerons, rudder, etc…). Vacuum of space would cause damage to the structure not designed for that environment (Cockpit or any other pressurized areas could implode).

Is there a plane that can fly into space?

A spaceplane is a vehicle that can fly/glide like an aircraft in Earth’s atmosphere and maneuver like a spacecraft in outer space. … Three types of spaceplane have successfully launched to orbit, reentered Earth’s atmosphere, and landed: the Space Shuttle, Buran, and the X-37.

What happens if planes fly too high?

When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …

Can a plane escape gravity?

Why you can’t fly a plane to space

Part of the problem is Earth’s gravity. You need to escape it in order to reach space. This requires a minimum speed of mach 33 (25,000 mph). … Issue 1: Fewer air molecules means it’s harder for the plane to stay airborne.

Do planes fly over Everest?

Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. … This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.”

Why do planes do not fly over the Pacific?

The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.

How many feet up is space?

In the US, “space” begins at 80.4km (50 miles), or 264,000 feet. General international consensus sets a similar limit for the start of space as 100km (62 miles), or 380,000 feet. “Low Earth Orbit” (LEO), where many satellites live, goes from 160km (100 miles, 525,000 feet) to 2,000km (1,240 miles, 6.5 million feet).

Can an airplane fly with one engine?

Yes it can. A twin-engine aircraft can fly perfectly well on only one engine. In fact, it can even continue the take-off and then safely land with just one engine. Losing an engine in flight is not usually a particularly serious problem and the pilots are given extensive training to deal with such a situation.

Can drones fly in vacuum?

1 Answer. Airplanes, helicopters, drones etc all fly (produce lift) by displacing air downwards – so none of them could fly in a vacuum (neither could a bird or insect, even if provided with a tiny respirator).

Can an airplane stay still in the air?

Can an Airplane stand still in mid-air? Technically, it is possible for an airplane to hover for a few moments, but only in the rarest of circumstances. If weight and lift cancel each other out at the same exact time that thrust and drag cancel each other out, the plane would hover until one of these variables changed.

Why do aircraft fly at 35000 feet?

The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.

How high can airplane go up?

Most commercial aircraft are approved to fly at a maximum of around 42,000 feet. This maximum is also known as a ‘service ceiling.

Why can’t a fighter jet fly into space?

Jets cannot fly into space. Jets are ‘air breathers’ and require air and oxygen to work. Without air, there is no ‘lift’ and the engines will shut down if the air is too thin.

Can a bullet escape the atmosphere?

– When you fire a bullet upwards from the earth surface the bullet will immediately begins to slow down due to presence of air resistance and earth gravity. … First, the bullet would never escape the earth’s atmosphere. This is because the escape velocity for any object is about 11.2km/sec.

Can you fly a plane on Mars?

Until recently, no attempt has been made to fly an aircraft in the Martian atmosphere. On Mars, in fact, the air is much thinner than on Earth. This means that the air pressure is less than 1% of Earth’s. So, the main source of hesitation for engineers was whether there could be sufficient lift.
