Adding air-to-surface (ASM) missile capability to an existing UAV platform

Adding air-to-surface (ASM) missile capability to an existing UAV platform requires the existing sensor suites remain in place and fully functional to preserve the multi-mission role of a UAV. And in some cases, the existing sensor data will also be utilized in support roles for this new addition to the platform. The challenges are to find a solution that will fit within a minimal mechanical footprint, add the least possible mass and utilize the limited power available – a classic size, weight, power reduction (SWaP) challenge.

The power delivery network

A 28V MIL-STD-704F input to -28V at 300W is converted using a DCM isolated, regulated DC converter. The thermal, mechanical and density benefits of Vicor ChiP packaging allow for cost-effective power solutions with previously unattainable system size and weight. Coupled with the high efficiency gained through zero voltage switching (ZVS) topology, these modules provide superior power system performance in a wide variety of environments. In this application, the Vicor DCM3623 provides the DC-DC conversion with a wide input range of 16V to 50V, peak efficiency of 93.6% and power density of 818W/in3.
