The concept behind Buuma is based on a new trend started with the conversion of the well know Air Tractor spraying aircraft into a relatively cheap, and very sturdy attack aircraft.
The airframe is a modified version of a fixed-wing heavy-duty agriculture spraying with more than 3000 units flying worldwide. Buuma has a<150kg payload capacity (depending on the required endurance).
As a fully Tier 2 aircraft, Bumma complies with the following key basic specifications:
With inner structure built with North American Spruce, a light wood with excellent compressive and bending strength, withstanding heavy loads without breaking or buckling. The external fuselage is made of carbon fiber and plywood, and extra layers of fiber and Kevlar undereneath for kinetic protection.
Buuma is very light, sturdy, and designed for short takeoffs, and bumpy landings, aiming at maximizing payload capacity. It is carried in a trailer, and quickly assembled in the field.
