Sample Work Packages

Sample Work Package 1: 6 Degrees of Motion Flight Simulator Modernization (FSM) Project

1.0 Introduction

Describe the methods, tools, and workforce the offeror would utilize to plan, manage, and deliver the work products for the following notional Work Package. For purposes of this Sample Work Package, assume that the following is true.

The NASA Vertical Motion Flight Simulator (VMS) is a premier pilot-in-the-loop (PITL) flight simulation facility, which provides uncoupled six degrees-of-freedom (6-DOF) motion and unmatched vertical and lateral travel. The Flight Simulator has supported flight research in handling qualities, guidance and cueing display design and development, accident investigations, standards development, advanced flight control system design and development for aviation safety, and human factors since it became operational in 1975. The motion drive hardware and control systems have been adequately maintained but are significantly beyond their service life.

The NASA VMS offers an unequaled range of motion, moving as much as 60 feet vertically and 40 feet horizontally. Eight mechanically-coupled, 150-hp direct-current servomotors power the vertical motion of the cab and vertical platform through reduction gearboxes and a rack-and-pinion drive system. Four 40-hp direct-current servomotors power the lateral carriage along the vertical platform using reduction gearboxes and a rack-and-pinion drive system. Operational parameters of the flight simulator include motion control of a 140,000-lb cab at velocities up to 15 ft/sec and accelerations up to 22 ft/sec2. See figures at the end of Sample Work Package 1 below for reference.

2.0 Summary Scope of Work

The general scope of this project would be to: 1) modernize and increase reliability of the VMS by replacing the aging motor generator set and dc drives with modern ac motors and variable frequency drives, 2) improve the instrumentation and control systems, and 3) replace mechanical and structural systems, including drive shafts, brakes, gearboxes and motor mounts. This exercise involves describing the management and technical approach the contractor would use for the specification, selection and design of large machinery and machine-design components, with associated electrical power and controls connectivity, and the work force necessary to perform this project.

For planning purposes of this exercise, assume the government will provide a civil servant Project Manager, and Lead Safety and Mission Assurance (SMA) Engineer. All other project support would be provided by the contractor.

3.0 Project Requirements

Assume the contractor is expected to provide engineering and fabrication services for the project specifications, design, and implementation requirements. Work would include:

1. Develop digital controllers specifications for each axis and verify performance through modeling and simulations using the dynamic models.

2. Provide engineering services for specification and selection of motion system feedback sensors and transducers and validate performance through modeling and simulations.

3. Provide engineering services for the specification and selection of replacement ac motors, including gearboxes and motor cooling systems.

4. Provide design services for the Servo Control Computer hardware configuration and selection.

5. Design and fabricate vertical drive motors structural support and pinion housing attachment.

6. Design, fabricate and assist with the procurement of vertical drive motor drive shafts and flexible couplings and lateral drive motor adapter plate and coupling parts.
