Title: Michael E. Daniska and an Expandable Spar Filler Block Device.

Introduction

Michael E. Daniska is an inventor associated with Bethel, Connecticut, and United Technologies Corporation. His patent work addresses a component used in helicopter rotor construction. The available information identifies 1 patent associated with him.

Latest Patents

Daniska’s patent, “Expandable Spar Filler Block Device,” describes a device designed for use with a spar member in an articulated helicopter main rotor assembly. The device has two filler members and an expansion mechanism. The filler members are shaped to engage the spar’s inner mold line surfaces, while a tapered pull shim fits between them.

In the described installation, adhesive is applied to the spar-engagement surfaces and the pull shim’s tapered surfaces. The device is placed inside the spar cavity, and the shim is manipulated so its tapered surfaces slide against the filler members. This action pushes the filler members outward into contact with the spar’s inner surfaces.

Career Highlights

The patent reflects Daniska’s work on a mechanical solution for fitting and securing a filler block within a helicopter rotor spar. The design uses a tapered shim to produce controlled outward movement of the filler members and establish contact with the spar cavity surfaces.

Collaborations

Daniska is associated with United Technologies Corporation. Jeffry C. Purse is identified as a coworker; the available information does not specify his role in the patent.

Conclusion

Michael E. Daniska’s documented patent contribution is an expandable filler-block design for helicopter rotor spars, using a tapered pull shim to position the filler members against the spar’s inner surfaces.
