UCF Researching How to Fly Hypersonic in Rain
Imagine boarding a flight from Orlando to Los Angeles and instead of languishing on the plane for five and half hours, you arrive in about an hour, ready to enjoy the palm trees on the Pacific Coast six times faster. That may be decades away but the hypersonic propulsion technology that could make it possible is currently being developed in a University of Central Florida lab. UCF has been researching hypersonic propulsion for six years, funded by $7.86 million in grants from the U.S. Department of Defense, the Air Force, and other sources. A team of 33 students led by four faculty researchers is exploring and experimenting with this new technology. Hypersonic propulsion aims to send a yet-to-be-designed aircraft out of the atmosphere to travel at hypersonic speed, which is about six times faster than the speed of a commercial airplane. But this research goes beyond commercial travel and has become a competitive field among developed nations, said Subith Vasu, a professor in UCF’s department of mechanical and aerospace engineering. “Russia is working on it, China is working on it, and then other countries in the European Union, Japan, India,” he said. “It is very difficult, so nobody really has a real hypersonic vehicle. Some people claim that they have but it is only pretending they do because there are a lot of technical challenges.” One of those challenges could be the effect of rain droplets on a vehicle traveling at hypersonic speeds. Michael Kinzel, project co-investigator and assistant professor in UCF’s department of mechanical and aerospace engineering, said that every time speed is doubled, the impact force from a raindrop quadruples. With hypersonic speed, they are going six times faster. Researchers are trying to figure out how to design a vehicle that can withstand that kind of pressure as it travels through the rain.
