Federal Aviation Administration

William J. Hughes Technical Center

Structures & Propulsions Branch (ANG-E28)

Atlantic City International Airport

1.0 Introduction/Background

The Federal Aviation Administration’s (FAA) Structures & Propulsion Branch (ANG-E28) has a requirement for an Environmental Simulation System (ESS) for Electrical Propulsion System Testing. The components under test will be exposed to a range of temperatures and altitudes to explore their effects on the power distribution systems.

The Structures & Propulsion Branch located at the William J. Hughes Technical Center (WJHTC) in

Atlantic City, New Jersey requires an Environmental Simulation System (ESS) that can perform environmental testing. This ESS is to perform testing on electric propulsion units and other electrical components for the use in aerospace applications. The FAA requires the capability to perform combined temperature and altitude (pressure) simulation. The ESS must have the capability to support testing of electrical components under simulated altitudes and temperatures of up to 100,000 ft. above sea level, a minimum temperature of -60℃, maximum temperature of +170℃, and humidity of 5% to 95% RH at site-level pressure.

2.0 Scope of Work

This Statement of Work outlines the requirements for an Environmental Simulation System for Electrical

Propulsion Unit Testing. The contractor must provide design, manufacturing, delivery, start-up/commissioning, documentation, and warranty of an Environmental Simulation System that can provide testing capabilities for altitude, humidity, and temperature in compliance with the minimum technical specifications listed in Section 3.0, Minimum Specifications.

2.1 Schedule Work

The contractor must coordinate the work schedule with the COR/TOR, Site access is secure and additional times should be allowed for personnel and equipment to pass through

FAA Security Operations Center (SOC).

The chamber must be capable to structurally support altitude ranging from site level to 100,000 feet. The chamber must have all ports, connections, sensors, software to support the mechanical system that would provide altitude capabilities. The altitude range must be site level to 100,000 feet in 40 minutes or less, 50,000 feet in 20 minutes or less (clean and dry chamber). The system must allow altitude profiles to be programmed as ramp steps for controlling climb and dive rates at any desired rate less than the maximum chamber capacity rating. The system must control altitude to within 500 feet of the set point of altitudes below 50,000 and within 1% of altitudes above

50,000 feet.

3.1.5 Combined Environment

ESS must provide both cycling and steady-state altitude and temperature capability between +80

°C and - 40 °C at any altitude between site level and 65,000 feet.

3.2 Environmental Chamber

The environmental chamber will be primarily used to provide specific environments for high-voltage wires and components as the units under test (UUT). The conditioned space portion of the chamber will be positioned in a manner as to surround the UUT and place it in the specific environment. The chamber may also be used for environmental testing of other electrical components. The environmental chamber will seat on a concrete floor.

Minimum internal dimensions (working area) must be L 30” x W 30” x H 30”.

3.2.3 Available Space Dimensions

The available floor space for the chamber is 6ft x 6ft. A maximum height restriction of 10 feet exists in possible locations for the chamber.

3.2.4 Internal Liner

The chamber liner must be constructed of corrosion resistant materials and must ensure a hermetic seal preventing moisture migration into the chamber during low-temperature operation. All liner seams and corners must be designed to allow for thermal expansion during temperature cycling operation. All interior parts exposed to the chamber environments must be fabricated of corrosion-resistant materials. The floor must be sloped in a manner to direct all condensates toward a drain.

The chamber vessel insulation must be isolated from the working space.

3.2.5 Chamber Exterior

Panels covering serviceable components must be equipped with quick release fasteners for ease of access. Removable panels must be equipped with gasket seals to prevent ambient air and moisture migration into the insulation space during low temperature operation to prevent frost build-up and subsequent saturation of the insulation. The chamber exterior must be finished with a coating resistant to typical corrosive agents present in an industrial application per best commercial practices. The chamber must include an emergency stop on the control panel, a run time meter, a main power disconnect switch, a padlock to prevent chamber opening during operation and an adjustable control screen with the option to move both vertically and horizontally.

3.2.6 Conditioning System

Cooling, heating, and other related conditioning components must not protrude into the workspace other than the area specifically allocated for ESS and its supporting equipment. The air circulation system must assure proper air distribution and prevent air stratification throughout the chamber.

Condenser must be air cooled and must have the option to be located outside of the building on a concrete pad in which the ESS is contained as to not introduce excess heat into the working environment. The FAA will be responsible for creating the concrete pad on the exterior of the building. Alternatively, the condenser may be installed on the roof of the building in which the

ESS will be located.

3.2.7 Refrigeration System

The refrigeration system must use non-explosive and ozone-friendly refrigerants. Only ASME approved refrigerant vessels, over pressure limit cut-out switches, pressure relief valves must be used in the refrigerant systems (R-507 /R-508).
