MALE Drones
Medium-Altitude, Long-Endurance

High-aspect-ratio wings, tail surfaces, and landing gear create interference drag at every junction with the fuselage. Printed wing-root, tail-root, and gear fairings smooth those junctions with compound curves built directly from the aerodynamic surface, with no layup tooling to make or modify when the shape changes.

On a 24-hour aircraft, small drag sources add up to hours of loiter. Printed fastener covers and flush access panels clean up exposed hardware and give crews quick access to the systems they service between sorties.

MALE engines need steady cooling air through climb, loiter, and descent, and slow loiter speeds leave little ram pressure to drive it, so inlet design matters. Printed NACA ducts and cooling inlets integrate the flush inlet, diffuser, and mounting flange into one part, with heat-resistant Antero 800NA and Ultem 9085 for the zones around the engine bay.

Mission systems have grown faster than the airframes that carry them. Printed duct adaptors route cooling air from inlets to avionics and payload bays through a crowded fuselage, joining printed runs to off-the-shelf fans and heat exchangers.

MALE aircraft earn their keep carrying sensors: EO/IR turrets, synthetic aperture radar, and signals intelligence pods under the wings and fuselage. We print pod structures, internal mounting frames, and aerodynamic tail cones sized to each payload, so a new mission fit does not wait on a new mold.

Brackets, trays, and harness routing inside payload bays print with features consolidated and threaded inserts installed in-house, cutting part count on the installations that change most often.

Endurance only matters if the aircraft stays connected past the horizon. Printed antenna buckets and mounting substructure hold SATCOM, line-of-sight datalink, and GPS antennas, with drainage paths and sealing lands designed into the part.

RF-transparent covers protect exposed antennas through thousands of hours of UV and rain. ESD-safe Antero 840CN03 shielding keeps payload electronics from interfering with the flight-critical receivers mounted beside them.

A MALE fuselage is lined with brackets: sensor mounts, avionics tray supports, antenna standoffs, and clamps for plumbing and harness runs, most of them low-volume part numbers unique to one station on the aircraft. We print them in Nylon 12CF where stiffness-to-weight matters and in Ultem 9085 where flammability requirements apply, consolidating the bracket, the standoff, and the clamp into a single part with threaded inserts installed in-house.

Harness runs on a long-endurance aircraft carry power, data, and control signals the length of the fuselage and out to the wings, through thousands of hours of vibration and thermal cycling. Printed cable coverings, raceways, and harness guides protect those runs, hold spacing from structure and heat sources, and follow the airframe contour without the tooling a formed cover would need.

Fiber optic lines for sensors and data links need routing hardware with generous bend radii, smooth surfaces, and no charge build-up near the optics. We produce thin-walled, static-dissipative fiber optic guides in ESD-safe materials, a part family we have built in production runs above 2,000 units for an aircraft program.

Mission computers, datalink radios, and payload controllers ride inside enclosures that must protect against static discharge, hold alignment through vibration, and stay light. We print electronics enclosures and avionics housings in intrinsically ESD-safe Antero 840CN03 and flame-retardant Ultem 9085, with cooling paths, connector cutouts, and mounting features designed into the housing.
