  • Dr. Zhimin Liu, Structures and Manufacturing

Boeing Research & Technology sponsored Manufacturing Influenced Design (MInD)

The shift from aluminum alloys to composites, while resulting in important weight reductions, brings a new set of issues and challenges to aircraft manufacturers

  • The increase in advanced materials usage invalidates the traditional empty-weight regressions used for conventional aluminum designs
  • Manufacturing processes are one of the main cost drivers for advanced materials
  • Therefore a non-weight based approach that brings structural, manufacturing and production planning considerations earlier in the design process is needed

Development of a framework that incorporates detailed material and manufacturing criteria to enable:

  • Product and process trade-offs in preliminary and conceptual design
  • Larger and faster design space exploration, increased design freedom & knowledge and design process improvement
  • The parametric and simultaneous evaluation and visualization of the impact that manufacturing, performance and operations constraints have on the design space

Development of the Manufacturing Influenced Design Space Exploration Tool (MInDSET) that allows the user to

  • Interactively and parametrically define various concepts of interest by varying the wing shape, material selection and manufacturing options (sheet metal aluminum, machined aluminum, hand layup composite, advanced composites, etc.)
  • Rapidly compare concepts in terms of performance, operations, and structures, and rank them based on user-defined preferences and criteria

Boeing Research & Technology sponsored Manufacturing Influenced Design & Production Optimization (MInD PRO)


Development of an environment that leverages the existing Manufacturing Influenced Design (MInD) framework to support the investigation of production planning’s impact on aircraft design and enable rapid trade studies and concept selections at early design stages. Particular focus on Demand Variability and Manufacturing Variability

  • Incorporate parametric production and scheduling models to existing framework
  • Parameterize and abstracts production planning constraints that are integrated into the aircraft design space
  • Integrate cost models to existing parametric formulation
  • Assess and visualize trades between wing design, factory layout, and profitability over the life of a program

Development of an interactive and parametric environment that leverages surrogate modeling techniques and visual analytics to support decision making and enable rapid trade studies and concept selections at early design stages. In particular, this environment called MInDSET PRO allows the user to:

  • Parametrically and dynamically evaluate and visualize the impact that performance, manufacturing and production constraints have on the design space
  • Gain insight into the efficiencies of the different processes
  • Quickly identify the critical path and potential problem areas in the production flow
  • Conduct real-time trade studies between factory throughput, flow time, workstation utilization rates, recurring and non-recurring costs, and aircraft performance
  • Trade between adding stations vs. hiring workers vs. adding tools to achieve a desired throughput for a parameterized wingbox
  • Identify planform designs and factory settings that reduce cost over various demand scenarios for the entire production life of a design
  • Visualize the use of resources over time

Boeing Commercial Airplanes sponsored Manufacturing Influenced Design

Development of an evaluation tool set to evaluate design and manufacturing concepts against performance and manufacturing cost:

  • Use of proprietary data
  • Concepts included: Aluminum, Aluminum-Lithium, monolithic machining, composites with autoclave cure and non-autoclave cure
  • Disciplines involved: aircraft sizing, aerodynamics, loads, aeroelasticity, structures (FEA), manufacturing, uncertainty modeling and quantification, decision making


  • Rapid design and manufacturing M&S to bring a new material/manufacturing concept from its initial development phase to large-scale assembly level design applications
  • Explore and visualize sensitivities and design space
  • Compare various concepts of interest against performance and manufacturing cost

Triumph sponsored Integrated Structural Sizing and Manufacturing Research

Development of an in-house toolset to design and analyze primary structures and estimate their manufacturing cost

  • Use of proprietary data and tool development validation against actual results
  • Disciplines involved: aerodynamics, loads, structures (non-FEA), manufacturing, decision making
  • Based on classic structural analysis theories and corrected by Triumph’s decades of experience


  • User friendly GUI to easily set up a study and generate report
  • Customizable modules for different needs
  • Rapid modeling and simulations: minutes from setup to results

Integration of Supply Chain Networks into the Early Phases of Aircraft Design


  • The parts and services provided by the suppliers make up 65% to 80% of the final cost of aerospace products.
  • With the utilization of composite materials, the designs of the major aerostructures become drastically different, which require new suppliers with more advanced manufacturing capabilities.
  • Due to the coupling of the aircraft design and supply chain, it is essential to integrate the two disciplines starting from the early phases of design

Objective: Study the benefits and impact of integrating supply chain constraints to enable trade studies in the early phases of aircraft design. Achieved in two parts:

  • Design a global aerospace supply chain
  • Create an integrated environment to study the relationships between aircraft design and supply chain networks

Quantitative Technology Assessment for Joint Multi-Role Rotorcraft

The Joint Multi Role (JMR) family of vertical lift aircraft is a group of as many as 4 future vehicles intended to fulfill all the vertical lift needs of the Department of Defense. The Army in particular presently has a highly diverse fleet of helicopters and unmanned vehicles which incur high costs due to their high utilization and lack of commonality. A family of aircraft with common architecture has the potential to reduce costs for parts, maintenance, and training, but must also include improved performance and flexibility if it is to perform the same mission roles currently occupied by a wide array of specialized vehicles.

Rotocraft 2.png

New technologies must be implemented in order to meet the required improvements in vehicle performance. ASDL is using the NASA Design and Analysis of Rotocraft (NDARC) code to identify rotorcraft technologies at the component level that offer the biggest impact in terms of performance such as increased speed, range, and payload. The goal of this analysis is to quantify the possible benefits of specific technologies such as advanced turboshaft engines, flow control, and high efficiency drive systems with respect to attributes affecting performance such as fuel consumption, airframe drag, and hover and cruise efficiency. Cost and risk associated with technological development will be included with performance analysis, and advanced design methods such as Monte Carlo simulation and Design of Experiments will be utilized to search for performance and cost-optimized portfolios of technologies to aid the JMR family of rotorcraft.

Quantitative Active Rotor Technology Assessment of Rotorcraft in Full Spectrum Operations

The helicopter rotor system encounters a wide range of aerodynamic and structural phenomenon, such as dynamic stall, compressibility effects, flutter, and vortex interaction. These conditions make the helicopter loud, and also cause the rotor system to transfer large amount of vibration into the helicopter, its crew, and cargo. Mitigation of these negatives, which are inherent to the rotor system, can be accomplished through advanced control technologies known as Active Rotor Technologies (ARTs). These technologies are capable of inputting control forces at frequencies greater than 1 per rev, which is known to help reduce vibrations, noise, power, or some combination thereof.

Rotorcraft 4.png
Rotorcraft 5.png

In order to better understand the value of these Active Rotor Technologies from a systems level, research is being performed into the operational and costs and benefits of ARTs. These include vehicle level impacts, such as part life, fatigue, and mission performance; operational impacts such as maintenance time, vehicle availability, replacement parts, and capability; and costs such as RDT&E, as well as operational costs. This is being accomplished through a mix of expert judgment, high fidelity modeling and simulation of rotor systems and parts, operational simulation, and vehicle performance modeling and design. These various techniques are merged together to understand the total impact of ARTs at every level of helicopter operations.

Micro-Autonomous System Research MASR


The Micro Autonomous Systems Research MASR project focuses on techniques for applying new manufacturing technologies (3D printing, CNC milling, etc.) in a way that allows for combat invention, innovation, modification, and manufacture to be forward deployed. This new capability enables improved soldier flexibility to create materiel solutions to the problems they face. The MASR project is seeking to build the engineering techniques necessary for forward deployed innovation through an initial case study involving Micro Autonomous Systems. The initial case study will focus on demonstrating an extensible framework for enabling rapid progression from requirements definition to small scale production. The current phase of research is seeking to demonstrate the extensible design framework through the creation of a parametric multi-rotor vehicle and a parametric fixed wing vehicle. These two test prototypes are being used to develop three critical components: automated design, automated manufacture, and the link between the two. The case study will provide insight into how critical interfaces and components need to be documented and linked to modeling and engineering analyses for design generation. These designs will then be paired with automated manufacturing techniques to produce physical prototypes. The final product of the research is to demonstrate the end to end process from requirements to a workable prototype in a matter of days.

Video Showing the Generation of New Multi-Copter Designs in Response to Updated Requirements Entered in a Spreadsheet

In this project, sponsored by the Army Research Laboratory, the Georgia Tech team developed an automated product family engineering process and toolset allowing the creation of tailored one-off solutions to soldier needs. The toolset provides a simplified user interface for non-technical users to enter vehicle requirements, such as sensing packages, endurance, etc. A spreadsheet logistics interface allows an untrained logistics operator to enter machines and parts availability constraints. This information is fed to set of engineering analyses where a feasible design (if possible) is generated, and the drawings for manufacture are output. These part designs are then be provided to a technician with automated manufacturing tools (such as 3D printing) who starts the automated manufacturing, assembles components, and returns the tailored UAV to the soldier. This process has been tested and validated via flight tested vehicles
