"My Hartzell propeller is simply bulletproof. As the lead pilot of “The 4ce” formation aerobatic team, I need to have 100% trust not only in my teammates, but in my Hartzell prop to run smooth and reliably…with only a couple feet of separation between our planes, there is no room for “second best.”Īerobatic Performer, Matt Chapman Airshows I have met and worked with the people of Hartzell Propellers…each and every person there takes the same pride in the design, manufacturing and support of their props as I do flying behind it. I take great pride in flying American made. With so many aspects in the airshow business to worry about…its nice to know that my Hartzell propeller isn’t one of them…its always been ready.and has never let me down. My sponsor depends on me to be at the shows on time and ready to perform…without my Hartzell propeller mounted up front, I don’t think I could deliver with such confidence and reliability. Couple this with its 100% reliability over the past 14 years, and you have a winning combination.

I have never been let down by this prop…in any way! It has been reliable and maintenance free for all 14 years, other than a fresh coat of paint! The performance I get from the Hartzell propeller is truly second to none. I have been running the Hartzell propeller for over 14 years. "I depend on my Hartzell propeller to help me do the job…without fail. Rapid delivery of a new replacement propeller was exemplary and lead to our company exploring 4- and 3-blade Hartzell propeller options for reduced noise emission important in our operation." Most recently, we have appreciated the prompt and effective support of Hartzell when an unexpected hitch on prop overhaul had our C208B grounded at a peak time. "The Hartzell 3-bladed scimitar prop has really enhanced the GA8 Airvans, in our experience providing smooth and improved climb performance with a significantly improved noise footprint. When the propeller overhauls are due, we recommend the Hartzell Propeller Service Center to our customers." “Failure is not an option.” Hartzell Propeller Service Center gives us that quality.

With any component that we install on our customer’s aircraft, the quality of the product must be to the highest standard. The personnel in Piqua, Ohio go above and beyond to get propellers back into our hands so we get our customers back flying. The overhaul turn time is continuing to be reduced without jeopardizing the quality of the product.
Keeping the propellers turning is what the customer expects along with the feeling of safety and trust. "Jet Air has been using the Hartzell Propeller Service Center for over 5 years and to date we have not had a warranty or workmanship issue. "Stevens Aviation uses the Hartzell Propeller Service Center for our propeller overhauls because of the turn time, price, experience and the ease of doing business. Their customer service, quality of work, and quick turn times sets the highest standards in propeller services."ĭirector of Maintenance, Muncie Aviation Company That’s why Muncie Aviation Company trusts the Hartzell Propeller Service Center for all of our propeller needs. "Muncie Aviation Company strives to set the highest standards in the maintenance industry by providing the best service possible with the least down time for our customers. We and our customers count on Hartzell’s propellers and they don’t let us down.” As the propulsion system is the main source of the ship exciting forces thereby nowadays prediction of the ship low frequency noise due to propulsion system becomes important to naval designer for designing a comfort accommodation areas for the crew onboard the ship."The excellent design, manufacturing and support team at Hartzell Propeller is indisputably an integral part of Piper’s legacy and of our current-day success. In addition, at the structural resonating modes of the propeller and the ship. This work shows a numerical method enable to measure the structural and acoustic responses of the ship at propeller rotating speeds.
Finally, the acoustic responses of ship super structure under propeller excitations are predicted using BEM in time domain. The mathematical models for the ship and the propeller have been built and validated using computational fluid dynamics (CFD), then unsteady simulation done to obtain the transient responses of the propeller excitations.

The study investigates the ship acoustic responses due to fluctuating forces induced as a result of interaction between a 4-bladed propeller and Bulk Carrier ship 35,000DWT at full scale. Abstract: In order to achieve the acoustic comfort design for ship accommodation areas, This paper introduces the noise prediction of ship’s superstructure cabins based on boundary element method (BEM).
