Aerodynamic Optimization of Automobiles by Plasma Ionization/Active Flow Control/Virtual Aero-shaping
Problem: The ever-increasing fuel costs and shortage of fuel globally is an impending issue in the automotive industry. Aerodynamic drag is an unavoidable issue experienced by vehicles, especially on the highways. A lot of fuel is wasted to overcome the drag and propel the vehicle forward. Optimization of the drag experienced by a truck can majorly reduce its fuel consumption in the long run. Conventionally, this was done by changing the shape of the vehicle to optimize the aerodynamic flow about it. Also, drag reduction devices are also utilized to provide enhanced vehicle aerodynamics. However, these methods have proven to be not very effective over the long run.
An innovative solution has emerged to solve the above problem. It employs the usage of a Virtual Shaping Technology which can control the flow separation around the vehicle. It is much more beneficial to heavy duty trucks. This system can generate a body force which controls flow separation from a vehicle. By controlling flow separation, the drag force on a vehicle is minimized. A vehicle can be streamlined independent of its actual shape. Plasma actuators ionize the local airflow to induce a similar affect without the added structural components or weight. Even the best designed physical devices attempt to divert flow, unlike plasma’s which modify the existing flow field.
How does it work:
It decouples the aerodynamic performance from the actual shape of objects by changing the way air and objects interact. By placing the modules in key locations, aerodynamic performance can be increased by giving objects a virtual shape. Modules are made of piezoelectric material, no compressors are needed, just a simple electrical connection. A smart control system activates the modules only when there is a need, making the overall system highly efficient. The control system monitors in real-time the performance of the modules and streams diagnostic and performance data.
The process can be illustrated in two steps.
- Expansion & Air intake: The module takes in air through the orifice by expanding the piezo disks.
- Contraction & Air jet production: Once the module takes in the maximum amount of air, the disks contract and force air back out of the orifice. The force creates an air jet that establishes a virtual shape around the object.
- Modifies air flow instead of diverting it.
- Fully electronic with no moving parts.
- Low mass and fast time response.
- Significant improvement in fuel efficiency without any external add-ons.
- Same technology can be used in adding drag to vehicles for road stability, if needed.
Highly Durable Coatings
Problem: Durability is one of the oldest problems in the engineering universe. Automotives are much more subject to corrosive environments. Protection of parts is a major issue in this space. Material innovations are a major area wherein the focus is on to enhance the durability of structures.
Novel Solution: A company has developed a spray-on protective coating which can seamlessly adhere to any shape or surface contour. It can be applied to protect any type of vehicle exterior or interior. They’ve even been put to the test on the outside of storm-chasing rigs, enduring thousands of miles through high winds, debris fields, and hail storms — without fail.
The uniqueness of this material has been demonstrated in this video:
How does it work: Permanently bonds to most materials at the molecular level, creating a unique composite. A comprehensive coatings portfolio that includes polyurethanes, polyureas, aliphatic, and hybrid coatings. Each coating differs at a molecular level resulting in distinct physical characteristics that are ideal for certain applications and industries. Tensile strength, elongation, hardness, and UV stability are all factors that influence product performance and durability.
- Protects wood, metal, masonry, aluminum, concrete, cement, fiberglass, styrofoam, drywall and much more
- Extreme impact protection and abrasion resistance
- Custom color pigmentation
- Sound abatement and vibration dampening
