Balanceo del rotor

A 90-minute, 4-round basic Express simulation for Spanish vocational training (Formacion Profesional), module 1447 Aerodinamica, estructuras y teoria de vuelo, mandos de vuelo, sistema de conduccion de potencia y rotores (Tecnico Superior en Mantenimiento Aeromecanico de Helicopteros con Motor de Turbina, Real Decreto 1447/2018).

The learner is the newly qualified technician of a fictional small maintenance organisation at a fictional heliport in Galicia who runs the main-rotor track and balance of a regional operator's five turbine helicopters over the four quarters of a year.

Eight measuring and adjustment decisions over four rounds: how a new blade and the vibration kit are prepared, how the rotor is adjusted (pitch links, trim tabs, weights), how the vibration is followed between jobs, play found in the rotor head, what is done with a helicopter near its vibration limit in a fire season with no spare, the rotor records, the verification flight and the review of the year.

Scored on fleet available, rotor-programme cost a week, test flights wasted and vibration events; three tempting choices come back later, and two critical errors (a helicopter flown past the vibration limits of the manual, a verification flight written as flown without flying it) cap the round. Lesson: one adjustment at a time, and measure - changing two things at once hides the cause. Training level only.

Spanish primary, English parity. All companies, heliports, operators, helicopters and people are fictional.

An introductory simulation that assumes no prior knowledge of the subject, designed for undergraduate courses. It also works in vocational and high-school programmes and in onboarding sessions.
