Land Rocket Platform — From Three Separate Systems to One Integrated Solution

One of Türkiye's leading land rocket platform manufacturers wanted a single mobile power conversion solution for equipment needing power at different frequencies on its new-generation mobile rocket launcher: the fire-control computer, field communications and test equipment required 60 Hz, while the gimbal-stabilised targeting servo required 400 Hz.

The platform operates across very different climates and terrain, including desert, mountains and coastline. The power system must not fail during a launch window, and the solution was expected to meet MIL-STD-810F environmental and MIL-STD-461E EMI/EMC requirements.

Because the manufacturer could not find a military product on the market that offered both 60 Hz and 400 Hz outputs and was suitable for outdoor use, it had resorted to combining three separate systems. The available options were either limited to indoor use, restricted to a single frequency, or did not fully meet military requirements.

• An industrial 60 Hz static frequency converter (civilian-grade protection)
• An industrial 400 Hz rotary (motor-generator) frequency converter — noisy and heavy
• A separate smart PDU and distribution panel to manage the outputs

These three systems were assembled inside an industrial enclosure and mounted on the platform. The picture in the field was unacceptable:

• Weight and volume: the enclosure ate into the platform's payload capacity and took up critical space inside the vehicle.
• EMI: industrial products not designed for military EMI requirements emitted interference that affected the fire-control computer.
• Environmental durability: civilian-grade protection fell short in desert conditions, and the rotary converter could drop out in rain.
• Maintenance burden: three separate systems meant three maintenance schedules and three spare-parts stocks.
• Logistics: each system came from a different supplier, making procurement and integration long and complex.
• Cost: on top of the equipment itself, integration, the industrial enclosure and the cable harness all added cost.

The TEDEG Defence engineering team customised the PowerGuard Outdoor 115 VAC 60/400 Hz Military Mobile Frequency Converter to the project requirements, meeting all three of the manufacturer's needs in a single compact system.

PowerGuard Outdoor replaced the three systems inside the industrial enclosure with a single military system. What changed in the field on the pilot vehicles:

• Lighter, more compact installation: a single enclosure brought a clear gain in payload and mounting space on the platform.
• EMI: the interference from industrial equipment that had affected the fire-control computer was addressed through a filtering design based on MIL-STD-461E.
• Environmental durability: a single enclosure designed for outdoor use replaced the rotary converter that struggled in desert and coastal conditions.
• Maintenance and logistics: three maintenance plans and spare-parts stocks became one, with a single supplier and a single point of contact.
• Integration: with no need to combine three systems in one enclosure, pilot vehicle delivery was faster.

The platform manufacturer has adopted the same PowerGuard Outdoor architecture as the basis for its next mobile rocket launcher variants.
