10 things you must know about Solar Impulse 2
![10 things you must know about Solar Impulse 2](https://jetlinemarvel.net/wp-content/uploads/2015/07/Solar_Impulse_at_PHX_2_-_2013-05-08.jpg)
1. Flying Capacity : Solar Impulse is the only airplane of perpetual endurance, able to fly day and night on solar power, without a drop of fuel. Solar Impulse 2 will climb to 8,500 meters (5.28 miles) during the day, where it can reach its maximum speed and store more solar energy for the night. As dusk arrives, the plane will descend to an altitude of 1,500 meters (0.9 miles) where its speed slows and it’s easier to remain aloft.
2. Size : This revolutionary single-seater aircraft made of carbon fiber has a 72 meter wingspan (larger than that of the Boeing 747-8I) for a weight of just 2,300 Kg, equivalent to that of a car.
Structure : build the entire structure proportionately 10 times lighter than that of the best glider. Every gram added had to be deducted somewhere else, to make room for enough batteries on board, and provide a cockpit in which a pilot can live for a week. In the end, it is of the weight of a small van: 2’300kg!
3. Battery : The 17,000 solar cells built into the wing supply four electric motors (17.5 CV each) with renewable energy.During the day, the solar cells recharge lithium batteries weighing 633 Kg (2077 lbs.) which allow the aircraft to fly at night and therefore to have virtually unlimited autonomy
4. Motors : Four brushless, sensorless motors, each generating 17.4 hp (13.5 k), mounted below the wings, and fitted with a reduction gear limiting the rotation speed of a 4 m diameter, two-bladed propeller to 525 rev / min. The entire system is 94% efficient, setting a record for energy efficiency
5. Speed : Solar Impulse can fly at the same speed than a car, between 36 km/h (20 Kts) and 140 km/h (77 Kts).
(At sea level: minimum speed of 45 km/h (20 Kts) and maximum speed of 90 km/h (49 Kts). At maximum altitude: from 57 km/h (31,5 Kts) to 140 km/h (77 Kts).)
6. Robustness :
The upper wing surface is covered by a skin consisting of encapsulated solar cells, and the lower surface by a high-strength, flexible skin. 140 carbon-fiber ribs spaced at 50 cm intervals give the wing its aerodynamic cross-section, and also maintain its rigidity.
7. Simulation Training :
long-duration round-the-world flights by training them on virtual missions in the flight simulator. The idea is to test their ability to endure three days and nights alone in a cockpit of less than 9ft x 5ft x 3ft at an altitude between 3,000ft and 27,000ft. André Borschberg came through the first 72-hour simulation in 2012 with flying colors.
8.World Record
Solar Impulse with Bertrand Piccard, broke the world records of distance and duration for solar aviation, as well as the world record for the longest solo flight ever (117 hours and 52 minutes — around 7,200 km, 4,474 miles).
- Flight time: 117:52 hours\
- Maximum altitude: 8,634 m (28,000 ft)
- Average speed: 61.19 km/h, 38 mi/hr
- Flight plan distance: 7,212 km, 4,481 mi
9. Solar Impulse 2 Project Plan:
- 12 years of feasibility study, concept, design and construction
- 50 engineers and technicians
- 80 technological partners
- more than 100 advisers and suppliers
- 1 prototype (Solar Impulse 1, registered as HB-SIA)
- 1 final airplane
(Solar Impulse 2, registered as HB-SIB)
10. Pilot food & Exercise:
The pilot’s daily intake is 2.4 kg (5.2 lbs) of food, 2.5 liter (84.5 oz, 0.66 US gallon, almost 3 US quarts) of water, and 1 liter (33.8 oz, 0.26 US gallon, 1 US quart) of sports drink per day. His meals include a breakfast, a lunch prepared to be as similar as possible to homemade meals, and snacks including dried fruits and chocolate.During a typical 24-hour flight cycle, the pilot rests 8 times, averaging between 5 and 20 minutes per session. Borschberg also performed yoga 30 to 45 minutes a day to stay fit and prevent any potential negative effects of immobility.

Boeing, Antonov to Collaborate on Defense Projects
![Boeing, Antonov to Collaborate on Defense Projects](https://jetlinemarvel.net/wp-content/uploads/2024/07/Volga-Dnepr_Antonov_An-124-100M-150_and_Cubana_Ilyushin_Il-96-300.jpg)
– MOU represents Boeing’s commitment to work with Ukrainian industry
– Includes exploring opportunities for collaborating on in-country support of Unmanned Aerial Systems
A Memorandum of Understanding was signed today by Boeing and Antonov Company to investigate potential collaboration on defense-related projects.
“We’re happy to keep collaborating with the Antonov Company to help Ukraine’s economic development and expansion,” stated Ted Colbert, CEO and president of Boeing Defence, Space, & Security.

“This agreement demonstrates our ongoing efforts to find more opportunities to work with Ukrainian industry, which was underscored by our signing of the Ukrainian Defence Industry Compact earlier this year.”
The areas of potential collaboration identified in the agreement consist of training, logistical support and overhaul services for tactical Unmanned Aerial Systems utilized by the Ukrainian Armed Forces, which includes the ScanEagle. In addition, the companies will also explore opportunities for Antonov to provide engineering support to Boeing.

“A strong, innovative, and efficient defense industry is key to sustainable economic development and national security, and we are extremely excited to collaborate with Boeing,” said Ievhen Gavrylov, CEO of Antonov Company.
This agreement brings a whole new level of opportunity to implement the latest and most effective solutions – in addition to the possibility of future projects with Boeing in the aerospace and defense industry.”
