The aircraft without an engine can still reach a height of 27,000m

If successful, this special aircraft will conquer every record of previous altitude.

Normally, flying devices (such as civil aircraft) usually fly only in the troposphere or on the boundary between the troposphere and the stratosphere because the air density is very high, allowing the engine to have enough oxygen to supply it. when operating.

Moreover, to reach the stratosphere, it takes a lot of fuel and takes more time. The density of the air is thin, so the stratosphere is rarely due to strong convection currents, but this is also a little reason There are flying devices in the stratosphere because there is not enough oxygen for the engine to operate.

Fly to the edge of the universe without an engine

Flying in the stratosphere has many advantages, but only a few flying devices such as Concorde, military spacecraft like U2 and SR-71, MiG-29 or NASA weather balloons are possible. works in the stratosphere.

The world record for altitude belongs to the SR-71 Blackbird aircraft made in July 1976 with 26,000m (equivalent to 85,069 feet).

It must be added that when humans exceed the height of 19,000m - or Armstrong Limit - it is extremely dangerous because some body fluids will boil. Unless the pilot wears clothing under pressure.

Its goal is to conquer the highest height a human can achieve.(Perlan Project Image).

Only one aircraft can overturn the record of SR - 71 when its goal is to fly at an altitude of 27,000 meters above Earth, at the point of contact with the universe.

This display is named Perlan 2 Glider by Airbus Group (USA), with wingspan of 25m and weighs only 816kg (enough room for 2 pilots and some scientific equipment).

Perlan 2 Glider will break the world flight record.

What is special is that it does not even have an engine but only moves by "surfing" the strong air traffic flows in the polar tornado (mountain waves, only in the stratosphere).

The Perlan Glider plane will completely change people's perceptions of moving in space if it succeeds in conquering its goals.

Perlan will move based on the mountain wave in the stratosphere.(Internet photo).

In 9/2015, Perlan 2 succeeded in the first test flight when conquering 1,500m altitude.

However, Perlan 2 has not yet achieved its goal when it has reached a height of 27,000m because it has not had favorable conditions as tornadoes in the stratosphere.

Why is flying in the stratosphere a difficulty but also an advantage?

Air layers on the ground.(Internet photo).

Although civil aircraft sometimes fly in this area when the weather is bad, they are only limited in altitude. That does not mean that the stratosphere is not convenient for flying.

In fact, when flying on this floor will save fuel, aircraft are more durable, more productive and faster (due to no air resistance), especially the type of jet powered gas (gas type) There are many in the stratosphere).

Flying in this gas layer also helps to avoid many dangerous dangers like birds or bad weather, swirling air currents.
