Chapter 1836 Broad-minded

Previous page        Return to Catalog        Next page

    When humans first flew into the sky, they relied on hot air balloons. Humans can finally use the buoyancy of hot air balloons to offset their own gravity, thus ascending to the sky and seeing the world in the sky.  After that, people began to use hydrogen balloons again.  Hydrogen balloons soon became widely used because no heating was required.  Before World War I, hydrogen-filled airships were already a very common means of transportation.  It's a pity that the safety of this kind of transportation is not good. If the huge airbag is accidentally damaged or even burns, it will be disastrous because a serious accident has occurred.  So the airship quickly disappeared.  After that, airplanes appeared, and human beings finally got wings and could fly into the sky.

    Although humans no longer use balloons and airships as means of transportation, it does not mean that these things are useless.  On the battlefield, these things are still of great use.  For example, in London, England, balloons are often used for air defense.  These balloons are not just used to cover up important targets, even the ropes tied under the balloons, and some may also be things like fishing nets, which will work wonders.  If there is an enemy plane flying over, then the enemy plane can be hung up.  This weapon even had a good effect within a certain period of time.  The German pilots suffered so much that they had to install a special sharp knife on the wing to cut the thing hanging from the balloon.

    It's just that in this era, balloons are still used for air defense operations.  Using balloons to attack enemies is rarely thought of.

    This is what Major Kromlin admires most about Qin Baoshan. This person has a very broad mind and can often think of something different. Moreover, the final facts can prove that his thinking is correct.  of.  Now, no one knows exactly what the Japanese bombed America with.  Everyone was speculating, but no one thought that the Japanese might use hydrogen balloons.  Only Qin Baoshan's thinking was broad enough to think of these things.  And after getting this conclusion, and then speculating, you can find that it can perfectly match the facts.

    When things like hydrogen balloons fly over, there is no sound.  And because the timer is inaccurate, and the wind is also fluctuating, it is possible for these things to fly anywhere.  In this way, when the bomb is dropped, it will not be accurate.  But because it is carried by a balloon, the bomb is still relatively large, just like a large bomb dropped by a bomber.

    At this time, Cochrane had completely forgotten what happened just now. When she heard Qin Baoshan talk about the hydrogen balloon, she stopped, turned her head, and looked at Qin Baoshan.  Full of admiration.

    "Qin, you are really amazing. Let's go find those balloons now. But if they are balloons, why don't we try to find them at high altitude?"

    Anyway, it is impossible to fly side by side with Qin Baoshan, so even if it is an L-2 plane with a single cockpit, it is fine.  Now Cochran wants to know why Qin Baoshan intends to find the remains of the balloon from the ground, rather than from the sky to find the balloon.

    Qin Baoshan touched his nose, does this still need to be explained?  Of course the balloon blew up.

    If the Japanese were carrying out this operation, they must have done various tests.  After this kind of balloon flies into the sky, only at the most suitable altitude can it be affected by enough suitable airflow and blow all the way to the continental United States.  When the timing fuze works and the bomb falls, the original balance is destroyed.  The balloon flies smoothly in the sky, so the buoyancy is naturally equal to the gravity.  As the bomb falls, gravity eases, so the balloon must go up.  And it will rise very quickly.  Because the heaviest part of the whole device is the bomb below.  Once the bomb goes down, the buoyancy force will be far greater than the gravity force, and the balloon will whiz up to the sky, the height will become higher and higher, the air will become thinner and the air pressure will become lower and lower.  In this way, the balloon will get bigger and bigger, because the balloon has to balance the pressure difference between the inside and outside.  Only after the balloon becomes larger, the volume of the gas inside becomes larger, so that the pressure will decrease.  In this way, the balloon is getting bigger and bigger, and it must have been blown up in the end.

    Doesn't Cochran know such a simple truth?

    Seeing Qin Baoshan's bewildered look, as if wondering why Cochrane didn't even know this kind of common sense, Cochrane couldn't help but stomped his feet, and then boarded the plane aggrieved.

    Of course I know it, I just want to say a few more words with Qin Baoshan.  This kind of flattery made Cochran feel that he was too condescending, but this Qin Baoshan didn't appreciate it, and really thought he was a fool.

    Cochran made fun of himself, so he had to get on the plane.  Since there was only one L-2 plane, Major Cromlin took Wei Dayong onto an O-47 plane.

    thisThis aircraft was produced before World War II, so it is very different from the l-2 aircraft.  Although designed as a reconnaissance aircraft, it uses a low-wing layout.  In other words, the wings of the aircraft are below the fuselage.  This is very convenient for pilots to get on and off the plane, as long as they step on the wings, they can climb up, but after reaching the sky, it is not easy to search downward, because the wings will block the large field of vision below, resulting in a blind spot for searching.  Therefore, after this kind of aircraft entered the army, it did not receive much popularity.  Soon it was relegated to target towing, coastal patrol, anti-submarine patrol and other duties.

    However, it cannot be accused of how inappropriate the design of this aircraft is.  After all, in the era when this plane appeared, many planes still had biplanes. This plane still has many advanced designs. At least it uses a single wing, but from the biplane to the single wing, after removing the upper wing and  In the selection of the lower wing, the designer chose to remove the upper wing, which is somewhat an oversight.

    As for now, as long as there is a plane that can go to the sky, it is enough, and there are not so many complaints. Wei Dayong got on the plane and still watched Qin Baoshan and his plane there. He must do his job well.  For work, you must be optimistic about Qin Baoshan.

    Both planes started their engines, and amidst rumbling roars, they slid forward at high speed, and soon flew into the sky.  Since Major Cromlin and Cochrane were flying, Qin Baoshan didn't have to think about flying. His eyes looked down, expecting to find traces of the balloon wreckage.

    My luck has always been very good, maybe I will find my target soon.  (Remember the site URL: www.hlnovel.com
