"My first thought was to build a blimp, giving you 'unlimited' flight time to solar charge batteries etc. My second was that Japan to USA is the same direction as Jet streams flow if I am not mistaken."

"In 1998 an Aerosonde UAV (2.7m wingspan, 20cc engine) managed to fly 3200km and cross the Atlantic ocean with 6 litres of fuel over 26 hours. This new challenge is a little over double the distance, but with an increase in scale and more modern…"

"Well, you could adopt an albatross strategy and include perching to solar-recharge, dynamic soaring and thermaling to do the business."

"Solar or diesel. Where's the Atlantik Solar team?"

Charles Blouin commented on Charles Blouin's blog post Pacific Drone Challenge
"With numbers: a 1000kg glider dropping 1000 m  and a glide ratio of 1:50 will require (1000kg * 1000 m * 9.81 m/s) = 9.8MJ. Thus, you need 9.8 MJ to travel 50 km. From there, you can figure out the specific energy density needed."
Wednesday
Charles Blouin commented on Charles Blouin's blog post Pacific Drone Challenge
"The glide ratio and the mass of the glider allow you to calculate the energy needed to fly a given distance. It is not an approximation: it represent the real energy loss due to aerodynamics effects. A motor will not be 100% efficient, so the actual…"

"Explain me please, what do you mean - climb 100 km?"

"As I wrote in the post: or realistically, climb 100 km over the whole trip.:)"

"Congrats! Any paper on subject is available? How difficult was the implementation with the Bebop platform and the motion capture?"

Charles Blouin commented on Zubax Robotics's blog post Evaluating the efficiency of a sensorless propeller drive using UAVCAN GUI Tool
"Interesting experiment! With complete characterization of the motor and propeller (using a dyno on the ground), you could obtain mechanical efficiency in flight with this."

Pacific Drone Challenge

Posted on January 16, 2018 at 2:29pm 9 Comments

The Pacific Drone Challenge, inspired by the Xprize, has the goal of pushing the boundaries of what is possible with civilian drones. You have to do it for your name in the history books as there is no financial prize. Could…

Thrust Stand for Large Motors

Posted on October 26, 2017 at 11:00am 1 Comment

My colleague and I received a lot of help from the DIYDrones community two years ago when we launched the Series 1580 with our company RCbenchmark. We had just finished our masters in robotics. After a lot of work, we are now releasing the Series 1780, a dyno to test motors and propellers producing up to 25 kgf of thrust.

Although this…

The Otus Tracker by RCbenchmark: a more affordable motion-capture system for drone development.

Posted on September 10, 2017 at 1:45pm 3 Comments

Almost a year ago, I posted here about how VR technology could help control and perform research on UAVs in an indoor environment and at a more affordable cost. Currently, the most advanced indoor UAV research lab in the …
