a college in Singapore has conducted some of the first purposeful flights of a solar-powered quadcopter drone.
The prototype has flown as excessive as 10 meters (about 33 toes) in verify flights the usage of solar power with no battery or different energy storage on board, in keeping with the national tuition of Singapore (NUS), which introduced that an engineering group had carried out the look at various flight.
“Rotary winged plane are drastically less efficient at producing raise in comparison to their fixed wing counterparts [so] a doable 100 per cent photo voltaic rotary plane that can take-off and land vertically is still a massive engineering challenge to this point,” the college pointed out in a press release.

however NUS mentioned its prototype can profit raise in a managed method, making it promising for useful implementation.
Some high-profile makes an attempt at setting up functional fixed-wing photo voltaic-powered drones have floundered, corresponding to fb’s Aquila, a high altitude platform station (HAPS) device, and Google’s Titan Drone program. And photo voltaic Impulse 2 is dealing with business-software hurdles after its 25,000 mile go back and forth all over the world. So, solar-powered drone success is certainly not a given.
constructed the usage of light-weight carbon fiber, the NUS quadcopter drone weighs just 2.6 kilograms (about 5.7 kilos) and has 148 silicon solar cells.
The drone can both be managed remotely or programmed to fly autonomously using a constructed-in GPS system.
functional purposes encompass photography, kit beginning, surveillance and inspection. NUS pointed out it may even be used as a so-known as ‘flying solar panel’ which would provide emergency solar energy to disaster areas.
And in scenarios when sunlight isn’t purchasable, batteries can also be equipped to energy the drone.
“on account that 2012, eight NUS student groups have made successive design improvements and worked in opposition t a fully-photo voltaic powered plane,” NUS mentioned in the observation. the primary “solar-assisted” version developed by students in 2012 may handiest get 45 p.c of its flight energy from solar cells. The relaxation of the energy in that version got here from on-board batteries, NUS referred to.
