As a new energy power ultralight aircraft, the flight of the electric version of the Cessna 172R will not bring you much amazing performance, and Scott is the first time to fly an electric aircraft, before the extreme parameters of this power system are not clear, he can not fly any particularly dangerous actions, just fly a take-off, climb, turn and other actions, and it will take more than 10 minutes to land. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"How?" As soon as Scott landed, Alex. Durand asked him eagerly.

"There is still a bit of a lack of power." Scott said very politely.

For this evaluation of Scott, Alex. Durand didn't feel anything wrong at all, the total power of the two motors is only 60kw, compared to the fuel version of the 172R, the power of more than 200 horsepower is indeed a little worse, it is already very good to fly, and the better propeller can make up for the gap in engine power a little. Durand, in anticipation, nodded and said, "In addition to motivation, what about other aspects?" For example, manipulation and the like. ”

"That's a lot better," Scott couldn't help but smile a little on his face: "The whole powertrain feels smooth, like a silk scarf running over your hand, and the most intoxicating thing is that there is no deafening roar of the engine, it feels like driving a glider with auxiliary power that glides at high altitudes, I have to say, this *feeling is wonderful......"

Alex. Durand interrupted him, he didn't come to listen to Scott say this, and asked eagerly, "If we launch a trainer with this powertrain." What do you think? ”

"Excellent!" Scott immediately said without hesitation: "Boss, I have to say." If it is only for the flight instruction of junior cadets, there is no more suitable than this...... If you can increase the power level and increase the area of the wing. Then it's just perfect. ”

Although Scott is a Cessna special pilot and test pilot, he does not look at this electric version of the Cessna 172R from the perspective of a special pilot, on the contrary, he really looks at this aircraft from the perspective of a rookie who has learned to fly. If there are some small situations that can be handled by yourself, this is considered a qualified pilot and can get a pilot license, and it is perfect to use such a power system to do the teaching of primary pilot training.

Alex. Durand immediately turned his head to look at Lin Zheng and asked eagerly, "Then Mr. Lin ......?"

Know Alex. What did Durand want to ask, Lin Zheng said with a smile: "We are developing a new generation of electric motors, and after the successful development of a new generation of electric motors, the power is expected to reach 40kw and the weight is expected to be reduced to 30 kg." ”

"Okay, great......" Alex. Durand was overjoyed.

Now the power system on this aircraft is 80 kg, 60kw. The new generation can be lifted up to 60 kg, 80 kW? The dead weight has been reduced by 20 kg, and the power can still be 20kw? This is equivalent to an increase of at least 100 kilograms of thrust, for Alex, who has eaten aviation meals for decades. Durand, for his part, knows all too well what this level of performance boost means for a light aircraft.

Eagerly grabbed Lin Zheng's hand. Alex. Durand said excitedly: "Mr. Lin, I think it is necessary for us to deepen our understanding on a broader scale, what do you think?" ”

"Of course." Unceremoniously laughed at Alex. Durand extended an olive branch, Lin Zheng smiled: "Being able to cooperate with an industry leader like Cessna." It's our pleasure. ”

Cessna needed such a low-cost teaching aircraft, even though the 500-kilometer range was less than a third of that of the gasoline version of the Cessna 172R. But its cost advantage is too great, the cost of using less than $5 per 100 kilometers is enough to offset his short legs, and Alex. Durand is confident that he can increase his range by removing more weight and increasing the number of batteries in the later refinements.

"Ahem......" Scott interrupted Alex with two light coughs. Duland's words: "Mr. Lin, may I ask how much does your power system cost?" ”

That's right! Scott's question made Alex fall into a frenzy. Duland's head suddenly lightened: Damn, how did you forget such an important issue?

Electric aircraft do have an advantage in terms of flight cost, but if the powertrain is too expensive, it may not be a good thing for potential customers of the Cessna 172R, considering that a Cessna 172R with a basic configuration is less than $30,000, and the top-of-the-line version is less than $50,000.

"$55,000." Lin Zheng quoted a high price without hesitation.

$50,000?

Alex. Durand and Scott frowned at the same time: the price ......

Is $50,000 expensive? In fact, Cessna has been tracking the new energy power system, with the current international cost of lithium-ion batteries, the cost of lithium-ion batteries per kilowatt-hour, that is, the cost of lithium-ion batteries per kilowatt-hour is nearly 1,000 US dollars, and the battery pack of 20 kilowatt-hours needs almost 20,000 US dollars; The price of such a large power density motor and a permanent magnet is of course even more expensive, and the price of $55,000 is really not high, but compared to the price of less than $30,000 for traditional power, this price is indeed a bit difficult to choose.

"The price of $55,000...... It's just too expensive. "Like Alex who was poured a basin of cold water by Lin Zheng. Durand said to Lin Zheng with a wry smile.

"That's right, it's not cheap," Lin Zheng also undertakes. But he shrugged: "But you should understand that this is definitely the most technologically advanced and lowest-cost power system that can be taken out in the world." ”

“……”

Alex. Durand and Scott nodded wordlessly. They had to admit that what Lin Zheng said was actually quite right.

Alex, who was finally stimulated by this price and calmed down a lot. Durand, thinking for a moment. Cai said: "Mr. Lin, in any case, Cessna is very interested in this new powertrain, and I think it is necessary for us to cooperate further. ”

In any case, Cessna should be modified with a batch of Cessna 172R equipped with a new energy power system, and recommend it to major aviation training institutions, although the 500-kilometer range is indeed a little low, but compared to aviation training, this does not seem to be a big deal.

"It's our honor," Lin Zheng smiled and nodded. He didn't expect the two sides to reach a cooperation immediately, not to mention, Cessna at least had to spend more than half a year to evaluate the safety, economy and other indicators and parameters of the power system, and only after these evaluations were passed, the two sides would talk about the next step of cooperation, if even the preliminary evaluation could not be passed, the next step of cooperation would be impossible to talk about. As soon as the topic changed, Lin Zheng said casually: "We have also designed a new electric commuter autogyroplane, I wonder if your company is interested in cooperating?" ”

Well? Gyroplanes? Alex. Duland's interest really came: "Really? Where is it? Can I take a look? ”

The so-called autogyroplane. It's not the same thing as the U.S. V-22 "Osprey" gyroplane, which is now in full swing, and it looks like a helicopter with two long helicopter rotors on its head, yes. It's really the main rotor used in the airplane, but unlike the helicopter, the main rotor of this cargo is not powered. There was also no tail rotor, replaced by a pair of propellers.

When it comes to take-off. The propulsion propeller propels the aircraft forward, driven by inertia and drag. The main rotor or spin, when taxiing for a distance (usually 20 meters to 100 meters) can take off, do a good job can do only 20 meters to fly, and even with an auxiliary power system, you can take off directly vertically like a helicopter, this kind of main rotor with auxiliary power system autogyro is actually not much different from a helicopter, but the cost is much lower than that of a traditional helicopter.

At present, there is no large-scale popularization of autogyrometers in the world, the most important reason is that this cargo is not good to be bigger, the helicopter can only carry one person, the weight of only more than 100 kilograms of the "mosquito" helicopter to the load of 20 tons of Mi-26 "Halo" super heavy, but the autogyro is limited to the spin effect, can only achieve the maximum take-off weight of less than 2 tons, which greatly limits the use of this cargo.

But there is no doubt that if this product can be electrically powered, it has a great possibility to be realized as a commuter aircraft with a very low cost of use.

"I haven't started assembling yet," pointing to a few huge boxes in the middle of the venue, Lin Zheng said helplessly: "It is estimated that the assembly work will not be completed until tomorrow." ”

"It's a shame," said Alex. Durand was very depressed, but he had no choice but to ask, "So how is the performance of this plane?" ”

"It's pretty good," Speaking of this autogyro, Lin Zheng had a smile on his face: "This plane can carry two people, the flight distance is 200 kilometers, we provide a set of auxiliary power for the main rotor, and now we can do 15 meters of taxi take-off, our next goal is vertical take-off and landing......"

"Oh God," Alex. Durand was frightened and looked at Scott in disbelief: "Scott, did you hear that?" Skiing 15m ......"

"Yes, I heard that." Scott nodded again and again, he was also frightened, the 15-meter running distance can basically be used for many helipads, except for those dangerous rooftop aprons, basically can ensure the take-off and landing of this aircraft, and the 200-kilometer flight distance is a little shorter, but it is also so-so enough...... Of course, the most important thing is that the cost of this product is really cheap!

"Mr. Lin, as a senior member of the EAA, I solemnly invite you to participate in next year's Oshkash EAA Aerial Expedition." Scott's face suddenly turned grim, and he said solemnly to Lin Zheng.

"Uh...... eaa？ Lin Zheng was a little confused, and subconsciously turned his head to look at Alex on the side. Duland: What the hell is this EAA?

"EAA is the abbreviation of the American Test Aircraft Association, which is the world's largest air show of general aviation aircraft and self-made aircraft, and their EAA air expedition at EAA headquarters in Oshkash is one of the world's top aviation events, attracting heads of state, business executives and hundreds of thousands of aviation enthusiasts, more than 10,000 aircraft fly to participate in the event every year, and more than 500,000 aviation enthusiasts participate in the event," said Alex. Durand couldn't help but get excited, and said to Lin Zheng with a dance: "The local economy can grow by more than $100 million within a week of the event. ”

"$110 million in growth......" Lin Zheng nodded indifferently.

During Golden Week, Lin Zheng was really impressed by the sight of dozens of millions of people flocking to a certain city and boosting the local economy by a few percentage points.

"It's really an excellent idea," seeing that Lin Zheng didn't seem to care much about EAA, Alex. Durand said to Lin Zheng seriously: "You must know that the world's masters of playing airplanes will appear in the EAA aerial adventure activities, where you can see the most wonderful aerobatic performances, you can see the most outstanding technicians and masters, and it is also the best promotion channel for your products...... Lin, as far as I know, there hasn't been a real electric plane on the EAA so far, and if you guys do it, you're going to be famous. ”

This EAA is so powerful?

Although I have not heard of the existence of EAA before, it seems that Alex. Durand didn't look like he was bragging, Lin Zheng nodded seriously, and said to Scott: "Okay, thank you for the invitation, I will consider it carefully." ”

"I'm very optimistic about your products, really," Scott looked at Lin Zheng with a serious face, "You may not know, but this is the first company I invited since I obtained EAA Fellow Membership." ”

Foreigners are so subtle and tell you so bluntly, I gave you a big favor, but I have to say, no matter whether you want to go to EAA or not, Lin Zheng really accepts Scott's love. (To be continued......)
