Overheat indicator for attachment arm of blower casing of turbopropeller of aircraft, has studs extending between respective fixed end and free ends, where each stud includes material having glass transition temperature

摘要

The indicator (100) has frustoconical studs (110-114) extending between respective fixed ends (110a-114a) and free ends (110b-114b), where each stud includes a material having a glass transition temperature different from the glass transition temperature of the material of the other studs. Each stud is constituted by a resin identical to a resin matrix of a composite material part i.e. attachment arm (10). The studs are accommodated in a protective enclosure, where the enclosure is made out of a material having a melting temperature greater than the glass transition temperature of each stud.
