Project:
Perform all engineering tasks for the design and structural substantiation of a redesigned battery shelf for Beechcraft Bonanza A36.  A significantly larger battery was required to cold start the turboprop aircraft.

Customer:
Aviation Technologies, Inc.

Services Performed:
PEI provided design, analysis, and DER approval to support the redesign of the battery shelf 

Structural Analysis and  FAA DER Approval:

• Generate system level finite element models, baseline and modified
• Modeling of battery to determine center of gravity and tie-down locations
• Quasi-Static analysis with limit maneuver loads 
• Global Equivalency and Detailed Stress analysis, including mechanical joints (bolted and riveted)
• FAA DER review and approval
• Generation of FAA Form 8110-3 for approval of modifications

Engineering Design:

• Conducted site survey to measure and document Beechcraft Bonanza A36 battery compartment
• Modeled local aircraft structure in the vicinity of the current battery shelf
• Designed preliminary enlarged battery shelf and aircraft reinforcements required for higher loading
• After structural evaluation, completed detail design of new battery shelf and reinforcing structures
• Conducted Design Reviews with Aviation Technologies, Inc. representatives
• Generated all detail part, assembly, and installation drawings
