Xiao Weiguo said with a smile: "No problem!" We'll provide you with a detailed design later, so it's never too late for you to make a decision. The trainer attack aircraft you need, based on the MT-1 primary trainer aircraft originally provided to the Romanian Air Force, have been upgraded to a certain extent, and we believe that they can meet your needs. The performance of our MT-1 primary trainer aircraft must also be known to you, it uses a BMW 380 horsepower piston engine, equipped with turbochargers, 4-blade torque conversion propellers, tandem two-seater, retractable front three-point landing gear, maximum take-off weight of 1800 kg, empty aircraft weight of 1200 kg, maximum external weight of 150 kg, maximum range of 1200 km, maximum level flight speed of 330 km per hour, cruising speed of 260 km per hour, The endurance time reaches 5 hours, and the ceiling is 7000 meters. Now we can upgrade it to a 500 hp piston engine and a five-blade torque converter propeller, so that its performance will get a big boost! ”

Lemmon said happily: "Well, this trainer is very good!" At a time when monoplane fighters were still in their infancy, this trainer adopted the latest monoplane layout, and its performance greatly exceeded that of many existing biplane fighters in all aspects. Mr. Philip's proposal is very good, as long as it is replaced with a high-power engine, it will definitely be able to become a high-performance fighter. Of course, we hope that it can install the Vulcan cannon produced by your Dragon Soul Ordnance Complex, I wonder if this plan is feasible? ”

Xiao Weiguo didn't expect that this Lemon was an understanding person, and indeed the fighters at this time still used machine guns, and they were small-caliber, most of them were 7.7 mm machine guns, so the firepower of the fighters before World War II was not strong. Even in the mid-30s, the most advanced fighter designs in various countries were monowing. The metal-based structure and casing, the rear three-point retractable landing gear or the fixed landing gear with a streamlined casing, with a liquid-cooled engine design, increased firepower from rifle-caliber light machine guns to 12.7 mm or 0.50 inch or more caliber heavy machine guns or 20 mm cannons. But the MT-1 junior trainer with Vulcan cannon installed and engine system upgraded can be said to be able to compete with the fighters of the mid-to-late 30s, not to mention the current monoplane fighters with slow speed and weak firepower.

Xiao Weiguo knows the history of World War II. As late as 1939, the air forces of more than a dozen countries used biplane fighters to defend their airspace, and even in that year, a third of carrier-based aircraft squadrons in the U.S. Navy flew biplanes. Throughout the Spanish Civil War, in addition to Spain's own pilots, at least 10 biplane aces were born, 5 were Soviets, 4 Italians, and the remaining 1 was Serb. The recognized number one ace was Captain Joaquin Garcia-Morato on the side of the National Army, with 40 aircraft. However, due to the incomplete wartime data and the contradictions in the contents, the reliability of the results of the other aces is very problematic. Not to mention comparing and confirming each other. At least 17 pilots from other countries and 20 pilots from the Republican Army have been recognized as trump cards.

The biggest difference between a biplane and a monoplane is the flight speed. For example, the Bf109E fighter is 85-90 kilometers per hour faster than the I-153 and Gloucester "Fighter" MkII fighters. Next up is the British "Hurricane" MkI, which is 50 kilometers per hour faster than the Fiat CR.42. Of course, compared to monoplanes, biplanes are not without advantages at all, due to the small wing load, coupled with low speed, biplanes have better turning performance than monoplanes, and if used properly, this advantage can help the former thwart the monoplane's attack. Of course. In air combat, the slower ones are definitely at a disadvantage. Because for a fighter pilot, it is only by taking advantage of altitude and speed that he can win.

However, now Xiao Weiguo knows that not only has the time of the outbreak of the Spanish Civil War changed, but also due to the various advanced weapons sold by the Dragon Soul Ordnance Consortium to both sides of the Spanish Civil War, the course and outcome of the Spanish Civil War will also undergo unpredictable changes. But. One thing is for sure, sooner or later the biplane fighter will be eliminated, and now this process is likely to accelerate, with the emergence of the MT-1 primary trainer aircraft of the Dragon Soul Ordnance Complex, as well as advanced aircraft such as the M29 competitive aircraft. Monoplanes will accelerate the replacement of biplanes.

Xiao Weiguo nodded and said, "Not yet!" Mr. Lemmon also knows that our Vulcan cannon is a rotary tube gun, it has 7 30 mm barrels, plus the 30 mm caliber shells are relatively large, and the weight of the whole system reaches 800 kg, so it is difficult to fit the MT-1 primary trainer aircraft, which has a maximum take-off weight of less than two tons and a small body capacity. Moreover, the MT-1 primary trainer is the engine pre-scheme, such as the Vulcan cannon, a high-velocity rotary tube gun, is not suitable for installation in the nose part, the shooting coordinator can not solve the problem that the shells of the Vulcan cannon do not hit the blades, and the wing thickness and strength of the MT-1 primary trainer aircraft can not meet the conditions for installing the Vulcan cannon. So we can choose to install two 7.7 mm machine guns for it, such a firepower configuration is enough. What do you guys think? ”

Hearing Xiao Weiguo say this, Lemmon also knew that he couldn't force it, after all, Xiao Weiguo was an aviation expert, and if he said no, it would definitely not work, but being able to have an advanced monoplane fighter is already very good for Franco's army! You must know that the flying volunteer team sent by the Soviets still uses very old biplane fighters, Yi-3 fighters, and PO-2 biplane trainers, and they are wooden structures and canvas skins, which cannot be compared with MT-1 junior trainers at all. When they themselves have this upgraded brand trainer attack aircraft of the Dragon Soul Ordnance Complex, it will be equivalent to taking control of their own destiny.

Lemmon said happily: "Well, no matter what, this plane is already very powerful, and the firepower of two 7.7mm machine guns is not bad, we think this is also feasible!" When you have better fighters, we'll need them. ”

Xiao Weiguo nodded and said: "Okay, our upgraded version of the MT-1 primary trainer aircraft is going to be named A1 attack aircraft, it is the first fighter of our Dragon Soul Ordnance!" I'm sure it will show excellent performance on the battlefield and pilots will love it! (To be continued.) )
