Case Study: Hartzell Propeller improves product quality and reduces scrap with VIMANA

Improving Product Quality With Intelligent Alerts

Hartzell Propeller, the global leader in advanced aircraft propellers and composite blade manufacturing, needed a better way to monitor critical temperature and humidity-controlled rooms, freezers, and ovens in its composite blade facility. While existing monitoring and audio alarms helped, Hartzell wanted VIMANA to provide real-time process analytics, broader alerting, and historical context to better understand and prevent quality issues.

VIMANA implemented connectivity across multiple sensors and controllers, real-time dashboards, and alerting that notified the team when conditions moved outside control limits. With VIMANA, Hartzell improved response times, enabled data-driven decisions, and reduced critical conditions lingering after alerts; less than 10% remained 30 minutes after notification. The solution also helped Hartzell avoid over $470,000 in scrapped parts in a single incident, while uncovering process improvements such as better room insulation, vinyl curtains, and ceiling tile changes.
