How Big Can a Solar-Powered Drone Be? - WIRED
It's a exceptional idea: Put solar panels on a drone so it doesn't need a battery. Without a battery, you could fly a drone as long as the sun keeps shining. But if you watch the video, you'll attention right away that the drone is as thin as a sheet. The real question then, is what size and mass could this vehicle be and still run completely on solar power. I'm prosperous to answer the question and give you a solar-powered quadcopter calculator. But first, let's look at the physics and ideas that factor into this equation. Solar Power Power is defined as the just the same from time to time rate of energy usage (change in energy divided by change in time) and is measured in units of watts. Perfectly, you want all the power from the solar panels to be devoted to flying. This means there is no need for a battery to temporarily store energy—which is great, since that would add mass. But how much power can you get from a solar panel. The power output from a solar panel depends on the following values (with some commencing estimates from me):. The Sun, or rather the power from the Sun. The power per area of the energy from the Sun at the surface of Earth is about 1000 watts per nutritious meter. You can't really change this value unless you change the Sun (not recommended). (Represented by E ) The size of the solar panel. Bigger panels suck up more power. Let start off with about 0. 04 up meters. ( A is for area) The efficiency of the solar panel. Just because you get 1000 W/m hitting the solar panel doesn't mingy all of that goes into electricity. (Efficiency = e ) Orientation angle. If the sunlight is perpendicular to the solar panel, that's best. Of course the Sun is purposes not directly overhead. What about an incident angle of θ = 45°. With that, I get the power output as the following equation:. That's it for the solar power. Hovering Power The power needed for a hovering quadcopter is a mini more complicated. Nevertheless, this will work for any flying vehicle that hovers by pushing air down. Let's start with the nature of forces and gait. If you take an object that is at rest and increase its speed, this requires a force. The magnitude of this pushing force depends on the majority of the object, the change in speed, and the time over which the speed changes. Now replace this object with air—because that's what these flying vehicles use to fly. You can get a greater stick force by using more mass of air using a larger rotor area. You can also get more thrust by increasing the speed of the air. There is some more math involved here, but I am growing to skip it. ( you could look over this if you want ). But wait. We don't care about the thrust force, we want the power. If you extend the speed of air (with mass), this increases its kinetic energy. The faster you increase the kinetic energy, the more power it takes. This means that you could have a hovering craftiness with small rotors that pushes the air down really fast OR a large rotor that pushes the air down at a slower make haste. But the power isn't the same for these two options. Since the kinetic energy is proportional to the square of the velocity, the smaller rotor. Source: www.wired.com
Quadcopter Ditches Batteries; Flies on Solar Power Abandoned - Hackaday
It seems congenial of obvious when you think about it: why not just stick a solar panel on a quadcopter so it can fly on solar power. Unfortunately, physics is a cruel doxy, and it gets a bit more complex when you look at problems like weight to power ratios, panel efficiency, and be like tedious technical details. This group of National University of Singapore students has gone some way to overcome these complicated issues, though: they just built a drone that is powered from solar power alone, with no batteries or other power source. Their creation is a wont-built quadcopter made with carbon fiber that weighs just 2. 6kg (about 5. 7lbs), but which has about 4 square meters (about 43 on a par feet) of solar panels. By testing and hand-selecting the panels with the best efficiency, they were able to initiate enough power to drive the four rotors, and have managed to achieve altitudes of up to 10 meters. The students have been working on prototypes of this since 2012, when their from the word go version could only generate 45% of the power needed for flight. So, reaching 100% of flight power in the demo shown below is a significant take care. The slow incremental march of solar panels has, over the last thirtysome years, led to abilities far beyond anything I could’ve imagined when I blue ribbon played with them. Fixed-wing flight is one thing. it’s way more efficient and there have been solar fixed-wing drones for some however. This is a huge milestone and the team and their professor deserve plenty of attention and congratulations for achieving it. It paves the way for some unqualifiedly fascinating applications. Indeed, this is seriously amazing. If anyone had asked me, I would have said that it’d be impossible to get enough energy from the each solar cubicle to lift its weight, let alone the extra weight of the motors and frame. I’m glad to be proven wrong. I simulacrum future improvements in solar cell technology will allow for a sturdier frame and more powerful motors, to let it fly higher and not get blown away or torn singly by wind. I’d be interested to find out if there’s a diy community for high altitude drones in the way there is for balloons. I read a story hindmost week about a fixed wing solar powered drone that stayed in the air for about 26 days at a time. Something like that would be surprising to put a low-power cross-band ham radio repeater on. Or stick a OpenWRT wifi router on it and see how far you can get a wifi affiliation. Maybe that sort of distance would break wifi though. Get something like a LimeSDR and do a DVB modulation. I wonder how much more thrifty it would be in colder air. Solar cell efficiency is strongly temperature-dependent, and Singapore isn’t known for being frigid. The other way to get the grippe air, even in tropical latitudes, is to gain altitude. If this thing could climb a few km, the air temp falls off rapidly, and it would find itself with a oversized boost in power. But then at some point the air gets too thin for blades to push against. I don’t know how to run these numbers but I’m sure someone here can bring to light an ideal hover point for this thing, where its daytime energy budget would be strongly positive and it could afford to run a communications.

DJI Mavic 2 in Perspicacity Series – Part 1 – Intelligent Flight Battery - Heliguy Insider (press release) (blog)
The advertised battery moving spirit of the Mavic 2 Series is a maximum of 31 minutes in optimum conditions. This is the best flight time we’ve seen to age from DJI for a drone in the consumer and professional categories. It’s not a huge improvement on the original Mavic Pro, but any additional flight minutes are valuable when it comes to flying drones. Like with the Mavic Pro, the batteries on the Mavic 2 drones have a healthy and reliable fit in the drone. This is aided by the battery release which must be pulled down in order to remove the battery from the drone. Don’t install or remove a battery while powered on. The battery can be turned on/off by tapping then holding the power button. To interruption the power, just tap once and the LED indicators will show. Mavic 2 Battery Safety Mechanisms As typically found on DJI batteries, the Mavic 2 Intelligent Exit Battery is packed with safety features. These feature help to maximise the battery life and prevent damage to the battery and drone. Auto Perform – The battery will automatically discharge to less than 60% if left for more than ten days. The process of discharge usually takes three to four days. This prevents enlargement of the battery. Temperature Detection – The battery will only charge in temperature between 5°C and 40° Balanced Charging – During charging, the battery cell voltage is automatically balanced. Overcharge & Overcurrent Guardianship – For additional safety during charging, the battery will automatically stop charging when it reaches 100% or if an excessive current is detected. Transient Circuit Protection – The power supply will automatically cut out if a short circuit is detected. Hibernation Mode – The battery will automatically birch off if the battery is inactive for 20 minutes. If the battery level is less than 10%, the battery will enter its Hibernation Mode to prevent undying damage to the battery. The battery needs to be charged to get out of the mode. Battery Cell Damage Protection – A warning message will be shown in the DJI GO 4 app if any damage to a battery room is detected. Information about the battery can be found on the DJI GO 4 app. This includes the voltage, capacity and current. Warning messages will also be shown on the app if encountered as well as on the LED indicators as shown below. The LED indicators are numbered as follows:. LED2 blinks twice per in the second place – Over-current detected. LED2 blinks three times per second – Short circuit detected. LED3 blinks twice per minute – Overcharge detected. LED3 blinks three times per second – Charger over-voltage detected. LED4 blinks twice per seconds – Charging temperature is too low. LED4 blinks three times per faulty – Charging temperature is too high. Charging the Mavic 2 Batteries There are several options available to charge the DJI Mavic 2 Perceptive Flight Battery. Both editions of the Mavic 2 include the Mavic 2 charger and one intelligent flight battery as standard. Source: www.heliguy.com
