The BA609 Tiltrotor from Bell Agusta combines the speed, altitude, and comfort of a turboprop with the vertical takeoff and landing capabilities of a helicopter. The aircraft will fly in a variety of conditions from ice and snow to extreme heat. It seats up to nine passengers and has cruising capabilities of 25,000 feet. This aircraft presents a totally new approach to executive transportation, search and rescue and law enforcement applications.
Each BA609 Tiltrotor aircraft includes three hydraulic reservoirs developed by Pall Aeropower. Busak+Shamban seals are exclusively used in each of these reservoirs.
Busak+Shamban seals were selected for this application after successfully passing a five million cycle temperature endurance test on the first attempt. The Busak+Shamban seal configuration was the first and only seal configuration to successfully complete the full five million cycles. Pall Aeropower had tried unsuccessfully to pass the test for over two years, before involving Busak+Shamban in its project; the technical support of Busak+Shamban critical to the success of the project.
Pall Aeropower is moving forward with its qualification efforts based on the test results and will be using the Busak+Shamban seal configuration for the duration of the programme. Certification on the Bell Agusta BA609 Tiltrotor is expected in 2007.
