Chapter 276

Two weeks later.

Two-thirds of the 12th grade's 'Survival Practice Course' has passed.

Another week.

This class is over.

Then what is about to come is an extremely cruel assessment.

The credits last semester were only 10 points.

Skydiving accounts for five points.

Therefore, skydiving is a top priority for all students.

First week.

In addition to theory and parachute stacking, the rest of the skydiving class is simulated landing training.

After the first week, you can go on board for practical training.

But you can't skydive on a plane every day.

Weather conditions have a huge impact on skydiving.

Never mind the bad weather.

Even if the wind speed is a little bit high.

So out of the seven days in the second week, only two days are suitable for skydiving.

Today is the first day of the third week.

Although the temperature in Xinyang had dropped below zero, it was a sunny day.

God is good.

Perfect for skydiving training.

There is an airport at the Xinyang campus.

However, this airport is too small and can only be used for take-off and landing of small piston propeller aircraft such as the CJ-6 and Y-5.

at this time.

Four Y-5 small transport aircraft were parked on the apron.

Several instructors and students from other colleges are refueling and maintaining these Y-5 transport aircraft.

In the flight briefing room not far away.

Four flight school instructors and eight senior students were also putting on flight suits.

In the tower further away.

There are also instructors who take students to serve as tower controllers.

Even the radar stations, weather stations, etc. on the surrounding hills
Almost all of them are students from Kongda.

In the open space next to the apron.

More than one hundred students from the 12th class have gathered.

Fang Kai stood aside with his hands behind his back, while parachuting instructor Li Xingyun had a serious look on his face.

"Today is your third parachute training. This is the first time for all of you. So I won't say any more nonsense. I just want to emphasize two words: safe, safe, and damn safe."

"There are still ten minutes before boarding. Before everyone boards, I and other instructors will check his parachute bag. Again, if anyone's parachute bag is not folded properly, get out."

Pilots are not paratroopers.

So there is no need to master 'fancy' skydiving skills.

As long as we can land safely, that's all.

and.

Their umbrella bags are also special.

The towing hook of the main parachute is hung on the steel wire slide of the aircraft. When skydiving, the parachute can be opened automatically without even pulling it by hand.

However, if there is a problem with the main parachute, you still need to pull the reserve parachute manually.

Therefore, Li Xingyun and his colleagues attach great importance to the safety of the main parachute, and they are not allowed to board the plane until it has been checked and approved by the instructors.

"Oh, it's the Y-5 again. The first two times almost shook my heart, liver, spleen, lungs and kidneys apart. Now I'm afraid of the Y-5!" Zhang Jing, who was standing next to Jiang Chen, sighed and said in a low voice.

The Y-5 is my country's first self-made transport aircraft. Its prototype is the An-40 light general-purpose transport aircraft designed by the Soviet Union in the 2s.

This transport aircraft has obvious advantages and disadvantages.

Although it has been in service for more than 60 years, it is still active in my country's vast airspace due to its stable flight and low operating costs.

Moreover, the Y-5 transport aircraft has excellent low-altitude and low-speed capabilities and can fly very stably in a low-altitude and low-speed environment.

The take-off distance is short and the runway requirements are low.

Therefore, after the Y-5 prototype was finalized in December 1957, it was immediately put into mass production.

until now.

A total of seven or eight hundred were produced.

Widely used in training, parachuting, sports, transportation and agriculture.

The Y-5 transport aircraft adopts the ancient biplane design, with the upper and lower wings of unequal lengths, a full metal frame and skin.

The wing planform is rectangular.

The upper wing is equipped with full-span automatic leading edge slats, slotted trailing edge flaps and differential ailerons.

The lower wing is equipped with full-wing deployment slotted flaps. This flap design gives the Y-5 good short-distance takeoff and landing performance.

Not to mention on the runway.

It can take off and land smoothly even on lawns, concrete floors and other surfaces.

However, like all piston propeller aircraft, the Y-5 also has disadvantages such as excessive noise and excessive fuselage shaking.

to be honest.

The comfort is too poor.

It's like riding a tractor.

As the 'cradle' of the Republic's Air Force, there is no shortage of aircraft in the sky.

However, most of the planes in the sky are already very low-end.

For example, the CJ-6, and the Y-5.
"Stop complaining and check the folding of the parachute bag quickly. If it fails the inspection, you will be scolded to death by Fang Nao Ke." Jiang Chen whispered.

Zhang Jing curled his lips and replied, "We have just started the inspection. It will take at least two hours for us to get our turn. We still have time."

The academy will send two Y-5 transport aircraft for each parachuting training session.

It not only trains the driving skills of the seniors, but also meets the skydiving needs of the sophomores.

Ah!
Win-win.

Boom boom. Boom boom.
The four Y-5 transport planes have already made a deafening roar.

Slowly drove out of the tarmac.

In the shape of a straight line.

Prepare to take off one by one.

The carrying capacity of a Y-5 transport aircraft is about tons, and it can carry more than ten people.

So four Y-5 transport planes can transport a class of students.

Not a moment later.

The four transport planes successfully took off slowly.

When the planes climbed to an altitude of about 500 meters, they immediately changed to a level flight attitude, then dispersed and flew towards the airborne training ground not far away.

The height of skydiving is very important.

It can’t be too high.

It can’t be too low either.

If you are a novice, the skydiving height is generally between 500 meters and 800 meters.

Four Y-5 transport planes continued to climb.

Wait until the height reaches more than 700 meters.

The hatch was opened.

Then I saw white 'flowers' floating down from the sky.

Like large dandelions.

Not a moment later.

The four Y-5 transport planes flew back to the airport.

It's Class 2's turn.

Wait until all the people in the second flight have successfully boarded the plane.

Only then did Li Xingyun look at everyone in Class Three.

He said in a deep voice, "Open all your parachute packs."

Everyone did as he was told.

All opened parachute packs.

Li Xingyun immediately took several instructors to start checking one by one.

But everyone is more cautious about life.

So there is no problem with folding umbrellas.

Check is over.

Only then did Li Xingyun ask everyone to put their parachute bags back on.

Everyone's parachute is divided into a main parachute and a reserve parachute.

The main parachute is carried on the back.

The reserve parachute is hung on the chest.

After a while.

The four Y-5 transport planes flew overhead again.

Jiang Chen raised his head and took a look.

Then took a deep breath.

he knows.

It's his turn.
