Statement of Work

For

Ice Tunnel Testing For UAM/UAS Icing Research

Federal Aviation Administration

William J. Hughes Technical Center

Structures & Propulsions Branch, ANG-E282

Atlantic City, New Jersey 08405

1.0 BACKGROUND:

The Federal Aviation Administration’s (FAA) Materials & Propulsions Branch (ANG-E282) has a requirement for Ice Tunnel Testing for Urban Air Mobility/Unmanned Aerial Systems

(UAM/UAS) Icing Research. The purpose of this contract is to book thirteen (13) days of Ice

Tunnel Testing for UAM/UAS to measure ice accretion performance degradation values for future model verification, determine ice protection requirements for motor cooling paths, and to test new and novel Ice Detection Systems for UAM/UAS.

2.0 SCOPE OF WORK:

The FAA will be conducting ice tunnel testing on a seven-foot diameter three-blade rotor. The rotor and associated motor will be mounted on tilt stand that can be set in a hover configuration

(axis of rotation = vertical), a cruise configuration (axis of rotation = horizontal), and angles in between. The testing will be conducted with the rotor in the hover position at low speeds, the cruise position at speeds of up to 80m/s, and at least one position in between. Testing will be done in clear air, Appendix C icing conditions, Supercooled Large Droplet icing conditions

(SLD), and snow conditions.

The contractor must provide thirteen (13) days of tunnel time, which includes two (2) days of setup, ten (10) days of testing, and one (1) day for teardown. The contractor must have the capability of conducting testing on a seven-foot diameter three-blade rotor. Additionally, the contractor must provide 800VDC power with current up to 300A to power the motor that drives the rotor.

This research is being conducted in coordination with The Pennsylvania State University (PSU) who is working under a grant from the FAA. The tilting test stand, motor, rotor assembly, data collection system, and electrical speed controller for the motor is being provided by PSU.

3.0 Tasks:

The contractor must perform the following tasks:

3.1 The contractor must provide thirteen (13) days of tunnel time for testing, which includes two (2) days of setup, ten (10) days of testing and one (1) day for teardown.

Exact dates to be agreed to between FAA representative and contractor.

3.2 Six to seven days of testing must be performed in Appendix C Icing conditions; the remaining three (3) to four (4) days will be for testing in supercooled large droplet and snow conditions.

3.3 Contractor must provide 800VDC power with current up to 300A to power the motor that drives the rotor.

3.4 The contractor must provide the personnel, facilities, materials, resources, and equipment to accomplish the tasks specified in this section.

4.0 DELIVERABLES:

At the completion of the test, the contractor must provide the FAA with a report containing the tunnel parameters for each test run.

5.0 Period of Performance:

Test dates are TBD based on a mutually agreeable time. Testing will occur within one year of signature of this contract.
