Aerospace Engineering

 

Combustion and Shock Synthesis of materials

Research categories:  Aerospace Engineering, Chemical, Material Science and Engineering, Mechanical Systems, Nanotechnology, Physical Science
School/Dept.: ME
Professor: Steven Son
Preferred major(s): ME, AAE, MSE, or ChE
Desired experience:   Two or more years toward B.S. in engineer or science degree.
Number of positions: 1

The SURF student will work with a team to understand how reactive synthesis materials can be modified to enable successful synthesis of materials (such as cubic boron nitride) by shock-assisted reaction. A gas gun will be used to perform experiments. Dynamic experiments will be used to examine the response of the materials and final materials will be characterized.

 

Design and Testing of a Novel Concept for Variable Flow Pumps

Research categories:  Agricultural, Aerospace Engineering, Material Science and Engineering, Mechanical Systems
School/Dept.: Ag & Bio Eng. / Mech. Eng.
Professor: Andrea Vacca
Preferred major(s): Mechanical, Ag and Bio, Aerospace, Material Engineering
Desired experience:   CAD modeling / fluid mechanics / fluid power / labview
Number of positions: 1

The present project is aimed at realizing a prototype of a novel concept of pumps. The novel concept consists in realizing a variable flow regulation using the principle of external gear machines. The novel concept guarantees higher energy efficiency of the overall hydraulic system.

The student's contribution within this project will be the design of an actual prototype of the new concept, suitable to operate at a level of delivery pressure up to 10 bar. On the basis of fluid-dynamic simulation results, the student will design all internal parts and follow the manufacturing process. In the final period of the project, it is expected an experimental activity aimed at verifying the expected pump performance on a research test rig utilizing existing facilities at the Maha Fluid Power Research Center of Purdue.

 

Experimental Study of Breakage of Particles under Compression

Research categories:  Aerospace Engineering, Civil and Construction, Material Science and Engineering, Physical Science
School/Dept.: Aeronautics and Astronautics
Professor: Weinong Chen
Preferred major(s): Aeronautics and Astronautics, Materials Engineering, Mechanical Engineering, Civil Engineering
Desired experience:   Any prior experience of using servo-hydraulic machines will be helpful but not required. Microscopy (optical and electron) experience will also be helpful.
Number of positions: 1

Particles in granular materials undergo compressive loading during their manufacturing, processing, handling, transportation, and use. Under large compressive load, some of the particles break. Common example of this phenomenon is breaking of sand particles in sand bags when bullets hit them. Aim of this project is to obtain the complete understanding of causes of particle fracture and also assess the effects of various parameters such as material properties on how particles fracture. To gain this understanding, we need to perform a number of particle compression experiments in which one or two particles will be compressed between two stiff platens at a constant speed. The compression experiments will be repeated for five different materials: soda lime glass, silica sand, polycrystalline silicon, yttria stabilized zirconia, and acrylic (PMMA). The selected student will perform these compression experiments using the servo-hydraulic loading machine. They will then analyze the compression data using MATLAB. They will also observe the fractured particles under optical or electron microscope. The compression data along with the microscopy images will provide us a valuable insight into why and how particles fracture.

 

In Situ Strain Mapping Experiments

Research categories:  Aerospace Engineering, Civil and Construction, Computational/Mathematical, Computer Engineering and Computer Science, Industrial Engineering, Material Science and Engineering, Mechanical Systems
School/Dept.: School of Aeronautics and Astronautics
Professor: Michael Sangid
Preferred major(s): AAE, MSE, or ME
Number of positions: 2

The research we do is building relationships between the material's microstructure and the subsequent performance of the material, in terms of fatigue, fracture, creep, delamination, corrosion, plasticity, etc. The majority of our group’s work has been on advanced alloys and composites. Both material systems have direct applications in Aerospace Engineering, as we work closely with these industries. We are looking for a motivated, hard-working student interested in research within the field of experimental mechanics of materials.

The in situ experiments include advanced materials testing, using state-of-the-art 3d strain mapping. We deposit self-assembled sub-micron particles on the material’s surface and track their displacement as we deform the specimen. Coupled with characterization of the materials microstructure, we can obtain strain localization as a precursor to failure. Specific projects look at increasing the structural integrity of additive manufactured materials and increasing fidelity of lifing analysis to introduce new light weight materials into applications.

 

Laser Diagnostics Applied to Reacting Fluid Flows for Propulsion Devices

Research categories:  Aerospace Engineering, Chemical, Mechanical Systems, Physical Science
School/Dept.: Mechanical Engineering
Professor: Terrence Meyer
Preferred major(s): Mechanical, Aerospace, or Chemical Engineering; Physics; Chemistry
Desired experience:   Physics, chemistry, and mathematics courses
Number of positions: 1

Propulsion, transportation, and energy systems rely on the turbulent mixing and efficient chemical reaction of fuels and oxidizers. Such reactions can take place in the liquid, gas, or solid phases and are investigated using sophisticated imaging and spectroscopic techniques. The undergraduate research assistant will work with graduate students and research faculty to assemble and operate flow hardware, align and test optical diagnostic instrumentation, and help collect and analyze data acquired using such techniques. The flows are designed to simulate conditions that are present in a variety of practical devices. The student will gain valuable hands-on experience and theoretical background that will be of use in a variety of fields related to mechanical, aerospace, and chemical engineering, as well as gain insight into potential areas of research for graduate study.
