CASE STUDY:

Aircraft Engine Control System

Compact and flexible solution also reduced costs

The customer had an aircraft engine control system common to several engine platforms.  The control system monitored and controlled RPM, temperature, vibration, cycles, position, and other critical parameters to optimize engine performance.  The control system was comprised of several sensor boards and an FPGA central processing board.  

The customer elected to consolidate the various boards into a module, which ultimately contained several ADCs, DACs, memory devices and the FPGA processor.  The one device allowed them to miniaturize the control system, reduce costs and use the module across several future engine platforms.

ISI's Co-Development Process

Working with the ISI team is a highly collaborative engagement. The initial requirements customers bring are the starting point, but the big benefit comes as our engineers work to propose various solutions, including pros and cons of each. Those solutions include what many competitors can’t offer, which is in-house execution of nearly all aspects of the project.

Exchange technical details with customer to define challenges and establish scope of the project. 

Assess likelihood of achieving the desired outcome and estimate the required engineering effort.

A quote will be issued to include NRE charges, price for prototypes and production volumes, and timeline for completion.

Design work begins with a particular focus on manufacturability. Frequent technical exchanges with the customer ensure a design that meets their expectations.

Upon customer approval, ISI initiates orders with suppliers and starts developing tools, molds, fixtures, and other custom equipment as required.

After satisfactory prototype testing and customer approval, product is released for volume production.
