New Aerospace Testing Equipment
Designed & Built by The Hope Group

Partnering with a well known instrument and testing controls manufacturer, The Hope Group helped design and build specialized testing equipment for a cooling pump installation destined for high altitude aircraft applications. In the critical aerospace engineering environment, especially with sophisticated components such as this, it is not sufficient to test sample batches of manufactured parts. Rather, every single part must receive a full test to certify its fitness for use in the aerospace application.

Hydraulic and Pneumatic engineers at The Hope Group worked closely with the software and electronic specialists of the testing controls company to create an integrated design that would satisfactorily simulate the temperatures, pressures and fluid flow parameters of high altitude aircraft. The electronic coolant pumps, which would be built by an international aerospace company, required a specialized mobile cart that would move the component from fabrication to testing to delivery, within the manufacturing facility.

Fluid Control System

The Hope Group engineers and fabricators designed and installed the overall piping and fluid control system, which included component selection, sizing and testing. Considering the extremes of temperature and pressure, the correct hose, piping, fittings and accessories was of major concern. In addition, design consideration was given to the limitations of the assembly facility for mobility of the test equipment as well as the use of aluminum structural framing to allow strong but convenient piping and control installation. Components were selected for their durability and quality. This included the flow meters, pressure gauges, high watt power supply, custom fluid tanks and other specialized components such as a heater installation.

Other design considerations included allowing for the proper size and bending of piping in a manner which allowed a minimum of pressure drops and flow issues. This attention to detail permits the ease of maintenance and servicing for the future. Safety enclosures were also designed and built for the operators of the equipment. The entire machine frame was designed and built of aluminum structural material for its strength and light weight. The entire test stand was assembled at the 60,000 square foot engineering and fabrication facility in Northborough MA, which is the main headquarters of The Hope Group. It also operates in six other locations in New England.


An international manufacturer of aerospace components turned to The Hope Group to assist in the design and construction of an essential piece of testing equipment where high pressure, high temperatures and high flow requirements put electronic coolant pumps to the ultimate test.

Test Stand
The Hope Group worked closely with an instrument and testing controls manufacturer to design and build a specialized pump test stand for use in the manufacture of cooling pumps used in high altitude aircraft. The machine will test each manufactured part for compliance to standards.

Specialized Components
The test stand included LabVIEW software and electronic devices that were integrated into the structural aluminum machine frame. Other components included flow meters, pressure gauges, heaters, proportional 3-way valves, high watt power supply and a custom fluid tank.

Extreme Conditions
Design considerations included the extremes of temperature and pressure that the component parts would experience in flight. The test stand was designed to simulate the full range of environmental conditions that would be encountered at high altitudes and under adverse conditions.
