The classroom isn’t the only place for scholarship at Parks College of Engineering, Aviation and Technology. Students and faculty can continue their research in centers and labs in all fields of engineering and aviation.
The AirCRAFT Lab's goals are to leverage the advantages of Unmanned Aerial Systems (UAS) - versatility, low cost, flexibility, minimal risk overhead and the tacit acceptance of a potential loss. This makes them the ideal platforms for experimental evaluation of cutting edge, high risk/high reward flight control algorithms, especially those addressing adverse flight conditions such as failures of sensors and actuators.
We seek to address aircraft safety from a holistic perspective, starting from a more expanded definition of aircraft safety to include the performance of various sensors and actuators on the aircraft, its structure, the pilot who is flying, to the performance capabilities of the aircraft itself.
We also work on novel interfaces to drones - at the AirCRAFT Lab you can control a drone by talking to it, or by using gestures, or through virtual/augmented reality. We consider our drones to be like new born babies or toddlers and we play the role of parents and teachers and use neural networks/machine learning/supervised learning to help them - they are learning to understand their surroundings by recognizing the landmarks around them, create a maps with spatial relationships between them that will help them navigate a new environment without the use of GPS, using only their cameras.
Our drones are also adaptive; they can change their shape in flight to navigate through tight spaces; our unmanned systems are resilient - they are learning to continue flying even if they are damaged; our drones are friendly and like large crowds - they are learning to fly in swarms, and reconfigure themselves as a need arises; our drones are helpful - they can deliver bio-control measures for pest control in fields and farms; our drones are sentries - they are learning to recognize intruders (drones) and track them to keep us safe; our drones are also teachers - they are used in the classroom to help crystallize fundamental concepts through real world applications.

SLU’s Department of Aviation Science purchased and installed an Air Traffic Control (ATC) simulator system from ADACEL that includes a control tower and RADAR simulator labs. ADACEL is the same simulation system the Federal Aviation Administration and the Department of Defense uses to train active air traffic controllers.
The control tower simulator consists of three positions: local control, flight data and ground control. It is voice activated, meaning when students give instructions the computer recognizes them and responds accordingly. There is also a pseudo-pilot position for the control tower simulator to add and assist to different scenarios. The simulated airport consists of two parallel runways and one intersecting runway with one main terminal and two fixed base operators (FBOs).
The RADAR simulator consists of two radar scope positions: North-approach control and South-approach control. It also has two radar assist positions. The airspace consists of four arrival gates and four departure gates, and services the main airport and one satellite airport. The RADAR simulator is run by two pseudo-pilot positions.
The RADAR lab and the control tower lab are linked together so both labs work together as would a real tower and radar facilities. Students coordinate through intercom systems for arrivals and departures. Frequency radios are used to communicate with the simulated aircraft and students must practice crew resource management to facilitate the smooth flow of air traffic.
There are 50-plus air traffic control locally created scenarios ranging from the very basics of vectoring, taxiing aircraft to the runway, clearing airplanes for takeoff, and utilizing all four arrival gates and departure gates simultaneously. These scenarios incorporate a good majority of the air traffic rules associated in the FAAH 7110.65 rule book.
The purpose of the Center for Fluids at All Scales is to promote research and disseminate knowledge on the study of fluids at all physical scales, from the microscopic to the macroscopic. The center also aims to promote research on the application of fluid knowledge to various areas of the sciences and engineering.
Examples of current research include studies of the micron-sized channels in microfluidic devices and blood vessels, the turbulence found behind parachutes and aircraft, and the superfluid interiors of neutron stars.
CFAS is inherently a multidisciplinary enterprise that regroups researchers and students from Saint Louis University and elsewhere. CFAS sponsors monthly seminars on the activities of its members, as well as on research presented by visitors and guests. CFAS also aims to promote joint research projects regrouping experts of various disciplines and academic departments.
The purpose of this center is to provide specialized technological research and development in the area of sensor and sensor systems design and integration.
The center’s mission is to lead multi-disciplinary efforts focused on the systemic development and evaluation of sensor systems aiding in the creation of automated safety and security applications. The goal of these efforts is to design, implement and evaluate such embedded systems as solutions to emerging needs, and to disseminate these solutions as widely as possible through research, publication, education, training and consulting.
In the Collaborative Haptics, Robotics and Mechatronics (CHROME) Lab, our research is centered on how we can effectively promote effective human-machine interaction in numerous applications including education, medicine and consumer technologies. Here, engineers work collaboratively with professionals to create new technologies that make the world a better place.
In medicine, we work with neurosurgeons to design steerable devices that can remove tumors in the brain through a single, small hole in the skull. We frequently meet with surgeons to brainstorm new ideas and progress on current ones, and we often get to observe the surgeries that we are working to improve.
The CHROME Lab joined forces with SLU neurosurgeon, Richard Bucholz, M.D., and his talented team to perform automated neurological assessments toward increasing the accuracy of post-surgical assessments of ICU patients and ensuring that no evaluations are missed due to heavy staff workloads.
In consumer technologies, we are building the next generation of touchscreens that will enable individuals to physically “feel” objects being displayed on screen. Imagine a touchscreen experience where you no longer feel the glass surface, but instead, textures such as slippery, sticky, bumpy or smooth. Imagine having to no longer constantly look at the screen in order to navigate on it, but instead, being able to feel your way around the screen. This is the experience the CHROME Lab is working to create.
In education, we are exploring how we can use vibrations and sounds on touchscreens to enhance the accessibility of science, technology, engineering and math (STEM). Because much of the content in STEM disciplines is visual, it’s challenging for non-visual learners, particularly those that are blind or visually impaired, to have equal opportunities in these disciplines. In this project, we work to promote a more inclusive, universal experience for students of all learning styles and are interested in understanding how we can leverage new touch capabilities to do this.

The system is used to evaluate the resistance of concrete to the ingress of chloride ions by indirectly measuring the degree to which chloride ions penetrate into saturated concrete. The system can also be used to measure the penetration depth of chloride ions after an electric potential has been applied to the specimen to determine the Chloride Migration Coefficient, which can be used to estimate the chloride diffusion coefficient for service-life calculations.
The cement autoclave provides an accelerated means of estimating delayed expansion of Portland cement caused by the slow hydration of calcium oxide, magnesium oxide or both. In this operation, changes in length of test bars are measured after being exposed to controlled steam pressure and temperature for a prescribed period of time. The Boekel cement autoclave is ASME certified and is the leader in expansion testing equipment.
This tool is used to perform freeze-thaw tests, dynamic testing of concrete specimens, assess uniformity of in-place concrete, and evaluate the expansion, bending and twisting of materials by measuring changes in resonant frequency. The unit consists of a 30-watt portable driver, pick-up circuit with a cartridge mounted on an adjustable metal stand and control unit with a 3-inch (76.2 mm) oscilloscope, voltmeter counter and amplifier. Amplitude and frequency of vibrations can be controlled in the range of 0 to 25 watts, 400 to 12,000 cps and frequency displayed within a 2 percent range.
Laser Peening is an emerging technology to improve the durability of precision metal components ranging from turbine blades and transmission gears to medical implants. The laboratory consists of a 1064 nm infrared pulsed laser, target positioning table, and associated optics. The lab is used to perform experiments involving laser-induced residual stress fields in precision metal components, with the intent to extend the fatigue life cycles. In addition, this lab is also used to investigate the interaction between nanosecond laser and metallic materials.
The focus of this lab is the development and evaluation of biomaterial and stem cell based therapies for the enhancement of skeletal muscle regeneration and function following injury, disease, and aging. The hope is to engineer functional skeletal muscle in vitro, which when implanted allows for full recovery of skeletal muscle structure and function in vivo. The lab also works on electrical stimulation as a new approach to physical therapy following skeletal muscle injury.

A major challenge of tissue engineering is to build three-dimensional in-vitro models for studying tissue physiology and pathology. Three-dimensional in-vitro models are the bridge between conventional two-dimensional tissue culture, which does not capture the complexity of human tissue, and animal models, which are costly, time consuming and raise ethical concerns.
The goal of our lab is to engineer and characterize synthetic biomaterials in order to provide a complete toolbox for building 3D in vitro models as platforms for toxicology screening and for the study of disease progression. Our current focus is on models of solid tumors as well as models to study neurotoxicity, a side effect associated with chemotherapy. In addition, we actively seek to apply our work towards other disease systems and congruous research areas such as biosensors and drug delivery.
