Novel lubrication systems for high DN, single and short mission bearings
Traditional oil and fuel/lube delivery systems used in limited life engines incorporate a bulky, centralized assembly with multiple sourced components leading to increased weight, supply chain complexity, and excess engine design modifications.
Zulu Pods’ proprietary oil delivery system features a decentralized, self-contained, hermetically sealed unit capable of developing pressure independent of a traditional central pump, plumbing, and reservoir. Limited life engine designers are now afforded performance optimizing benefits previously constrained by traditional lubrication systems.
Watch the video below to visualize our system in a short duration missile application.
Zulu Pods are able to develop fluid pressure independent of a central pump or piping, and can be installed in a static configuration to deliver lubricant to multiple bearings (red) from a single pod. In this application, the front pod (gold) is occupying unused interstitial space in the nacelle at the FWD engine bulkhead.
Zulu Pods are able to develop fluid pressure independent of a central pump or piping, and can be installed in a dual configuration to deliver lubricant to both the FWD and AFT bearings (red). Here, the pods (gold) are integrated both in the unused interstitial space in the nacelle at the FWD engine bulkhead and the tail cone.
Limited life engine design teams have broader options when deciding where the lubrication system should live. With the Zulu Pod system, custom tailored pods can occupy interstitial spaces - volumes within the engine that are normally unused.
In this application, the inlet cone (gold) houses a dynamic, annular (ring-like) pod that delivers fluid to the bearing working zone.
A Zulu Pods system can work as a fuel system, and can be designed to replace traditional fuel systems. This solution is retrofittable, affords faster start times while eliminating fuel interruptions, and can reduce parts count by up to 54%. In this application, the fuel pod is installed externally.
Applications for Zulu Pods technology extend beyond the examples listed above. Our R&D Engineering team can develop custom solutions that include the delivery of different liquids in addition to lubricants, customized size and fittings, and additional capabilities.
