Provided is a pneumatic tire having sufficient sealing performance. The present invention relates to a pneumatic tire including a sealant layer located radially inside an innerliner, the sealant layer being formed by applying a sealant to the inner periphery of a tire from which mold release agents have been removed.

Described herein are self-healing polymers comprising a base polymer and at least one healing agent disposed in the base polymer under pressure.

A gas turbine engine component (50, 100, 150, 160, 174, 206, 236), including: a surface (54) subject to loss caused by a wear instrument during operation of the component in a gas turbine engine and a performance feature (80, 82, 102, 152, 162, 172, 200, 230) associated with the surface. The surface and the performance feature interact in a manner that changes with the loss such that a change in performance of the gas turbine engine resulting from the loss is mitigated.

A new system a comprising a balanced belt that forms a ring around a wheel rim and enables smart wheel functionalities as positioning, sensing, actuation and communication hub is presented. The belt can be implemented as a removable apparatus locked around the wheel rim or as an integrate apparatus embedded in the wheel rim by a proper wheel rim manufacturing modification. The belt contains a tank filled with a sealing foam, which, in the event of a punctured tire, can be expelled out of the tank and injected into the inner part of the tire to repair the hole. With respect to the state-of-the-art systems, the proposed self-repairing tire solution, allows to avoid the cumbersome manual tire repairing operations, to save driver stress and time and to enhance car safety. Moreover, the proposed apparatus, by preserving punctured tire damaging, is very cost-effective respect to competitor solutions and contributes to carbon dioxide emission reduction. Finally, the proposed system is easy assembling, adaptable to different wheel rim sizes and reusable in case of car replacement.
