() Inspired by Archduke Ferdinand, the first thing Liu Fu did when he returned to Taiwan was to go to the Naval Shipyard and inquire carefully about the construction status of the Rosalia. After getting a positive answer from the engineers,
, Liu Fu immediately summoned all the projects that had participated in the design of the Rosalia.
division, and called the Taiwan Air Force Commander Ma Dan, and asked them to cooperate to design a large ship similar to the Rosalia, but this time it was not a civilian ship, but a warship, but this warship except
Except for the lower part of the hull, it is different from any other warship of this era.
According to Liu Fu's sketch, this peculiar warship looks like this, with a displacement of about 40,000 tons. The deck adopts an all-through deck, that is, the deck from bow to stern is connected into one piece, without any building blocking it.
, and the only building on the ship is the command tower located on the starboard side of the warship.
The purpose of doing this, Liu Fu also told these naval engineers and air force commanders, is that this is a ship that can take off and land aircraft, called an aircraft carrier. And this fully accessible deck is to allow aircraft to fly smoothly.
Take off and land.
After listening to Liu Fu's description and reading the sketches drawn by Liu Fu, several engineers looked at Liu Fu with suspicious eyes. Although they also knew that the small aircraft parked on the continental heavy cruiser could take off from the water, as
Shigeguru's eyes are very useful, but he
We still can't figure out the purpose of building such a large mothership specifically for these small aircraft. Does the president think that the heavy cruisers don't have enough eyes? Or is he planning to build a few more heavy cruisers to use
Does this mothership serve as eyes for them?
The engineers were thinking wildly, but Air Force Commander Ma Dan quickly understood Liu Fu's intentions. In many previous aircraft tests, Liu Fu had made requests to researchers at the Aircraft Research Institute to increase the load capacity of the aircraft.
At that time, aircraft were mainly used for
The institute still performed reconnaissance tasks for the navy and army, so the research institute paid more attention to the research of aircraft speed than the research of aircraft load. Liu Fu very resolutely issued an order, requiring the structure of the aircraft body and the
The load capacity needs to be focused on.
At that time, Ma Dan also asked Liu Fu privately why he valued the aircraft's body structure and load capacity so much. Liu Fu told him with a smile that in the near future, the Taiwan Air Force will no longer be an auxiliary arm of the army and navy, but will
As a main force, it will take on the heavy responsibility of attacking the enemy, and this heavy task requires the aircraft to be stronger and have a larger load capacity in order to carry more and larger bombs.
In the subsequent aircraft research, the Aircraft Research Institute began to focus on the load capacity and body structure of the two existing relatively mature aircraft models in Taiwan. In subsequent trainings, it arranged aircraft bombing projects.
Initially small mortar shells, and later specialized aerial bombs
, after many changes, the effect is getting better and better, and it is close to Liu Fu's requirements. However, for Liu Fu's other requirement, which is to carry torpedoes for sea attacks, these researchers tried their best and failed to do it.
There are two main reasons for producing a qualified attack test.
First, the load capacity of the two small aircraft is too small, and it is basically impossible to fly with a 450mm torpedo weighing 800 kilograms. However, it can be mounted with a large biplane, but because the large biplane is too slow,
The size was also too large, and this kind of aircraft was directly rejected by Liu Fu.
Second, after replacing with high-power engines, the two small aircraft could barely carry 450mm torpedoes and fly and drop bombs, but the flight conditions were very unstable. When dropping bombs close to the sea surface, they crashed into the sea several times. Not only did they lose
The plane killed and injured several pilots.
Seeing this situation, Liu Fu stopped using these two aircraft for testing, and instead asked the Aircraft Research Institute to develop a new type of aircraft. It can be used as a double-wing or single-wing aircraft. The speed cannot be too slow, and the load must be at least capable.
It carries a 450mm torpedo and can maneuver.
On the other hand, Liu Fu came to the Naval Research Institute to see if he could think of ways to improve power and torpedoes. In terms of power, the current small gasoline engine is already the lightest and most powerful aviation engine that the research institute can provide.
The engine has been installed. Although several engines with updated materials and stronger power are being trial-produced, there is still some time before finalization and mass production. As for torpedoes, the weight of the torpedo can be reduced by reducing the diameter of the torpedo, but the power cannot be guaranteed.
.
Finally, after weighing the pros and cons, Liu Fu decided to use 450mm torpedoes without reducing the caliber of the torpedoes. However, he could appropriately improve the torpedoes used by the navy. Since aviation torpedoes are all launched by aircraft very close to warships, such as
It was dropped within a few hundred meters, so there was no need to fly
It uses fuel to travel several kilometers, and because the aircraft is very fast, reaching about 80 knots, so depending on the inertia of the aircraft, the torpedo engine does not need to be too powerful, so reducing the weight of its engine and fuel can reduce the weight of the torpedo.
The size and weight of the torpedo do not affect the power of the torpedo.
Finally, after many discussions and tests, two aircraft and two torpedoes were finalized for use by the Taiwan Air Force and Navy.
The first one is a single-seat, single-engine biplane with a length of 10 meters, a wingspan of 15 meters, a height of 3.4 meters, an empty weight of 1,400 kilograms, and a maximum take-off weight of 2,600 kilograms. It is powered by a 12-cylinder piston engine providing 380 horsepower.
, top speed 155 kilometers per hour,
The endurance is 4 hours and 30 minutes, and the practical ceiling is 3,700 meters. The nose is equipped with a 12mm heavy machine gun with 500 rounds of ammunition. The belly carries a 620kg "Hai 1" 450mm aviation torpedo or 2 can be mounted.
250kg aerial bomb.
The second model is a single-seat single-engine monoplane with a length of 7 meters, a wingspan of 11 meters, a height of 3 meters, an empty weight of 1207 kg, and a maximum take-off weight of 2300 kg. It is powered by a 14-cylinder radial air-cooled engine.
Provides 510 horsepower, maximum
The speed is 185 kilometers, the endurance time is 3 hours and 30 minutes, and the practical ceiling is 3,400 meters. The nose is equipped with a 19mm cannon and 300 rounds of ammunition. The belly carries a "Hai 1" torpedo, or two 250mm cannons.
kilogram aerial bomb.
The two torpedoes are the 450mm "Hai 1" aviation torpedo and the 450mm "Hai 2" aviation torpedo. The difference between them is that the "Hai 1" uses thermal power propulsion, while the "Hai 2" uses a new
Lead acid battery and electric motor drive.
The "Hai 1" type is 3000mm in length, weighs 620 kilograms, has a warhead charge of 200 kilograms, can travel 1000 meters at a speed of 40 knots, and can travel 2000 meters at a speed of 35 knots;
The "Hai 2" type has a length of 2,700mm, a weight of 500 kilograms, a warhead charge of 135 kilograms, and can travel 1,500 meters at a speed of 33 knots;
These two aircraft have undergone many sea bombing tests and can be controlled relatively smoothly in various weather conditions. They are considered two successful naval aircraft and are named "Booby" and "Warshipbird" respectively.
However, Liu Fu did not immediately arrange mass production, but
The superstructure of a 10,000-ton old cargo ship was removed, a proposed deck was installed, and it was anchored in a block of waters outside the Keelung Military Port, so that the test pilots and researchers could begin to analyze the ship.
Conduct in-depth exploration and training on the subject of taking off and landing aircraft on a cargo ship.
