Onboard Generators

Most gas powered sUAS are fixed wing. There are a few large rotary wing sUAS.

• Most gas powered sUAS have onboard generators to supply power to the payloads and other operating systems. –
• Onboard generators supply a few hundred to a few thousand watts. They are very reliable and use little fuel.
• Current output varies with engine rpm, so this is monitored closely to avoid running below minimum requirements
• Battery backup systems, usually LiPo, are on board in case of generator failure. They provide enough battery power to return to home with the payload turned off.
