NASA LaRC Falcon HU-25A Crown Modification

The NASA Aerosol Cloud MeTeorology Interactions oVer the Western ATlantic Experiment (ACTIVATE) project seeks to address better understanding the interactions between aerosol particles, clouds, and the surrounding meteorology. PEI’s is assisting in the modification of a Facon HU-25A jet aircraft to install four research instruments aft of the cockpit on the fuselage crown. Support includes mechanical design, analyses of engineering designs, and FAA-level Designated Engineering Representative (DER) approvals of engineering data via FAA Form 8110-3. Combinations of these services including complete design solutions by the contractor, and analyses and approval of NASA design data are anticipated.


American Systems awards engineering support contract to Pagnotta Engineering for U.S. Marine Corps CH-53E Low Speed Precision Control (LSPC) System

PEI was awarded a contract by American Systems to perform the design and structural analysis of the Low-Speed Precision Control (LSPC) modification to the CH-53E Super Stallion for the United States Marine Corps. Among its many functions, the LSPC will allow the heavy-lift helicopter to land safely in a degraded visual environment (DVE), especially at night.

Previously, PEI supported American Systems on the design, analysis, and fabrication of the T-38 autopilot system for NASA Johnson Space Center.


Pagnotta Engineering, Inc. contracted by NOAA Aircraft Operations Center for engineering support

PEI is working on year two of a five-year support contract for the Department of Commerce, NOAA Aircraft Operation Center in Lakeland, FL. Under the current contract, eleven (11) task orders have been issued and seven (7) of those task orders have been completed. PEI supports modifications to several NOAA aircraft including the Lockheed WP-3D Orion, de Havilland DHC-6-300 Twin Otter, Gulfstream IV-SP, and Beechcraft King Air 350CER.

PEI completed the analysis and design of fuselage modifications to the WP-3D aircraft. The fuselage reinforcements were required because a new rack system with significantly heavier payload capacity (also designed and analyzed by PEI) was installed. The work required several site surveys to reverse-engineer the aircraft structure, as documentation on the aircraft is incomplete. Another completed task order was the structural analysis and approval of the Turnkey Airborne Gravity System (TAGS) in the King Air.

 


TRU Odyssey Simulator for the Bell 525 Helicopter

PEI continues to provide engineering support for the Bell 525 Odyssey Simulator including structural analysis, finite element modeling, and interface design. PEI evaluated alternative visual display solutions for the trainer, and also investigated the use of different materials for the support structures.  The Odyssey Simulator design allows for the reconfiguration of the trainer aircraft within a few hours.  The removable module that is interchanged includes the cockpit, control frame, and instructor station.
