用地球現有的科技打造出迪迦奧特曼劇中的科幻飛行器，勝利飛燕2號！丨魔界造物

My Victory Swift No. 1 Got 80,000 likes in just one day. You guys are awesome. So, that night, I created a folder for Victory Swift No. 2. For Swift No. 2 to take off, it's much more challenging than No. 1. In cartoons, flying machines usually defy Newton's laws, anti-gravity engines, alien technology, you name it. My skills are limited. Just utilizing some existing Earth technology. The first major issue with Swift No. 2 is its unusually small wings. And they're thick. With no airfoil. This results in poor lift performance. In reality, it wouldn't fly. So, I switched to standard model aircraft wings, maintaining the symbolism while slightly increasing their size. Increasing lift. The second major issue: The propulsion system. Swift No. 2's power is embedded within the wings, which I couldn't replicate. So, I adopted the same design as Swift No. 1, placing the power system at the rear fuselage. This time with a larger model of power unit, an 80mm ducted fan thruster with 3.5kg of thrust per unit. One unit fulfills the requirements. Intakes at the bottom and sides of the main body, exhaust at the rear—quite logical. Some aerodynamic optimizations at the rear to reduce air resistance. Overall, this is the result. Blueprints laid out, CAD arranged, laser cut, As usual, a thumbs-up to exchange blueprints. Isn't this too much? I've shared the blueprints in the bio and comments. I still have some of the boxes left from making Victory Swift No. 1. And with the approaching New Year, I've bought quite a few items on DeWu. These accumulated blue boxes can be used as the main material. These are all the pre-cut materials. The cardboard is sturdy but heavy. KT board is used to reduce weight in the wings and fuselage. The cockpit has many detailed structures ensured with 3D printing for realism. The mainframe and nozzles are also 3D printed. The texture of a real aircraft is designed. Very impressive. The exterior is prone to damage. So, the strongest cardboard is used. Now, assembly can begin. How's that? Starting to feel it? Let's spray a yellow primer next. Stick some colored tape. You know, shouldn't the director of Ultraman invite me to do props? Now, let's test the takeoff weight. The batteries are installed. How much? 2400g. Didn't spray paint this time. Feels about 5 to 10 grams heavier. Now, let's test the thrust-to-weight ratio. Okay, it's passing 1. Passed 1. Alright. Now onto simulated wind tunnel testing. Starting with a center of gravity test. Go. I feel like this No. 2 is more stable than No. 1. Much more stable than No. 1. Just feels slightly less lift. Now onto the thrilling test flight phase. Guess how many attempts it took to succeed. First test flight. Hand-launch directly into a high angle of attack stall. After the somersault, it exploded right underfoot. Damage to the underside of the nose. Luckily, it's not particularly serious. The main body of the wings is undamaged. Direct fiberglass repair for a full recovery. The second test flight. The hand-launch status is good, but the aircraft's lift is poor. Full throttle, but it won't climb. Ended up crashing straight into the farmland. The internal structure of the nose is mostly shattered. Had to return to the workshop for repairs and reinforcement. Once again, fully restored. Summarizing the issues from the first two attempts, Victory Swift No. 2 has small wing area. Insufficient lift. It feels very difficult to take off by hand launch. We decided to try a completely new takeoff method. Similar to wind tunnel simulation testing, we'll try takeoff from a vehicle. The car reached the cruising speed of Shengli Feiyan-2 Just leave it alone This is the safest way This Victory Feiyan 2 will explode a few more times It's basically going to be scrapped. no way This is the only way to take off Fine-tuning First, walk through the field at a low altitude speed Don't dare to lower it anymore Afraid of stalling This slightly larger wing Come again Turn right Ultra low altitude I'll try to see if I can straighten my movements. The throttle is now at full capacity Throttle full Can't hold it up anymore Turn left There is a high probability that you will not be able to pull the ball when you do a somersault. try it What a somersault Can't pull The wings are too small The steering surface is extremely small Rolling should be possible Come to the top of your head Yokoki Then dive Another dive He climbs very slowly. Large resistance, small lift Oops, the helm can still move. Did you smash Auntie’s carrot? Oh haha smashed one Lose 5 cents How much does a pound of radish cost? Fifty cents shouldn't be enough, right? Just hit this branch All the branches were brought down Cockpit ejection successful The cockpit has been ejected This Shengli Feiyan 2 took off and landed twice in total. Total flight time: 5 minutes I had to make an emergency landing once before. The aerodynamic shape of No. 2 is indeed not conducive to flying. Based on the current situation The throttle must be full the whole time Flight time 2 minutes It’s really hard to do without anti-gravity thrusters. Unless the wing area is increased Also optimize aerodynamic resistance Interested friends can give it a try Finally, I would like to thank Dewu for sponsoring this video of ours. Get something to help every young dream take off Everyone who wants to buy new year goods recently can go shopping at Dewu. What a bargain By the way, how many people want to see the Nantianmen Project? Still got over 80,000 likes I'll arrange it for you too Which model will be arranged first? White Emperor or Xuannv Post it in the barrage or comment area The one with the most starts first I successfully took off the Shengli Feiyan 2 Nantianmen’s plan is no longer difficult for me. At least the aerodynamic shape is much more reasonable than that of Shengli Feiyan II. The above is the entire content of this victory of Feiyan 2 Thank you for your likes and attention support Your support is my biggest motivation for updating See you in the next video Bye-Bye
