Expanded in-house test facility to support advanced aerospace, defence and marine systems

Marotta Controls to expand its test facilities to provide more capacity for aerospace and defence climatic and vibration testing and altitude testing.

Acoustic Testing – Poised to be the most advanced on the East Coast of the USA, a 1,600 square foot acoustic testing facility is being constructed for airborne and structure-borne noise testing. The lab includes dual acoustic chambers with high pressure and low-pressure testing capabilities at less than 40 decibels for frequencies ranging from 8 to 16,000 Hz. Testing will occur in short durations through a blowdown to atmosphere method — with max pressure and flow ranging from 650 PSIG (up to 28,000 SCFM) to 6,300 PSIG (up to 270,000 SCFM).

Vibration Testing – Air-cooled electrodynamic shaker systems will increase to three, each capable of 4,000 pounds of force (lbf). These systems offer velocities up to 70 inches per second (ips) for payloads up to 1,000 pounds and will be used for environmental screening of electromechanical actuation and advanced power systems.

Altitude Testing – Fifteen thermal chambers will simulate extreme conditions (-100°F to 300°F) at 120,000 feet. Additionally, a deep space vacuum chamber for satellite system testing will simulate environments at very high vacuum levels in temperatures ranging from -100°F to 300°F.
