![]() ![]() We would also like to achieve at least double that thrust to have a good control authority, so we will be looking for the propeller that is most efficient at 3.1 N, but can also achieve up to 6.2 N of thrust. We will therefore need to produce at least 12.5 N of thrust for the drone to hover (1.277 kg * 9.81), just over 3.1 N per propeller. Assuming all of our other components stay the same at 622 g, the total mass of our drone is now 1,277 g. This new battery weighs a whopping 655 g compared to our old battery that weighed just 155 g. The Turnigy 5000mAh 6S LiPo pack nicely fits our criteria with 111 Wh of capacity (figure 3).įigure 3: Turnigy 5000 mAh/ 111 Wh LiPo battery (Photo: HobbyKing) For this reason, we will start by swapping our old battery with a new battery that has around 100 - 125 Wh of capacity in order to increase our flight time. Up to the 0.2 hour mark there is an increase in flight time with increased battery capacity, but after about 100 - 125 Wh the marginal gains become less significant. Iteration 2: Choosing a New Battery for Maximum Flight Time This is where the design loop begins, as we swap components to try and build the drone that best meets our needs. If we increased the battery capacity, we could also increase our flight time, but the trade off would be increased weight. The battery’s capacity is just over 19.2 Wh (14.8 V * 1.3 Ah = 19.2 Wh), which occurs within the growth phase of the graph and gives us only about 4.5 minutes of flight time. We presumed our design would include a Turnigy nano-tech 1300 mAh 4S battery and included its mass in our overall calculations. battery capacity for the original drone design In our previous article, we modelled the flight time of our drone with varying battery capacity (figure 2).įigure 2: Flight time vs. Our goal is to maximize our drone’s flight time so that it can hover as long as possible. Other components (camera, frame, ESC, etc.): 460.5 g.We will assume the following mass breakdown of our 777 g drone: Once we found the most efficient combination, we had the tools needed to estimate our flight time, which is where we will start off today.įor this article we will be more precise with the mass of our components. Following these assumptions, we predicted we would need 1.9 N of thrust per propeller for hover flight, so we looked for the motor-propeller combination that would be most efficient at 1.9 N. We started our design process with the assumption that our drone would weigh 777 g and would be able to fly on its own. In this article we will start where we left off, looking at how our assumptions held up. ![]() ![]() In our previous article, How to Increase a Drone's Flight Time and Lift Capacity, we covered the first stage of the design process and reached a first version of our design.

After all, your health should always come first! Caffeine Cutting back on your intake of artificial sweeteners, caffeine, and sugar is the best way to ensure you’re protecting your health.

Thanks to Loach's use of amateur actors, it has a raw and real feel to it without being melodramatic. ![]() ![]() From peeing in a bottle to save time to seamless monitoring by an overlord hand-held device, Sorry We Missed You manages to capture the indignity and gives you an intimate introduction to the human cost of having everything delivered to your doorstep at a moment's notice. Gig economy workers are usually freelancers who own their trucks and are made fully responsible for packages until they reach their respective recipients.

While these are indeed the themes of this affecting drama, Loach always makes it about the people. The British social-critical director of I, Daniel Blake and The Wind That Shakes the Barley, Ken Loach, delivers another scathing indictment of our economic system, the slashing of worker protection, and the gig economy.
