Workers squirted smoke down a storm drain then watched to see where it came up. This is where it emerged from its underground meanderings.
Environmental factors, like wind gusts, can factor into an aircraft's performance. NASA's new heavy-lift launch vehicle, the Space Launch System (SLS), is no exception when it comes to Mother Nature.
NASA engineers and contractors recently completed liftoff transition testing of a 67.5-inch model of the SLS in a 14-by-22-foot subsonic wind tunnel at NASA’s Langley Research Center in Hampton, Va. Data acquired from the test will help prepare SLS for its first mission in 2017, Exploration Mission-1, which will deliver an unmanned Orion spacecraft to a stable lunar orbit to check out the vehicle's fully integrated systems.
Wind tunnel tests are a tried-and-true method to understand the forces an object may endure as it moves through the atmosphere.
Instead of learning how environmental factors affect the SLS only during flight, engineers have started at the beginning to improve understanding of how the environment also affects the rocket while it's sitting on the pad, ready for liftoff.
"In a typical wind tunnel test, we point the model into the flow field," said John Blevins, lead engineer for aerodynamics and acoustics in the Spacecraft & Vehicle Systems Department at NASA's Marshall Space Flight Center in Huntsville, Ala. "For the liftoff test, that's not the case. The wind is actually traversing across the model at much higher angles -- simulating a liftoff environment."
Engineers tested four different payload configurations of the SLS, carrying up to 130 metric tons.
"The test data is key to ensure vehicle control as we lift off and pass the ground tower," Blevins added. "At supersonic speeds, engineers can more easily compute the forces and moments, but that's more challenging at low speeds. This test is low speed, with winds in the tunnel only reaching up to 160 miles per hour."
With winds up to 160 mph over the model, engineers can measure forces and moments that the air exerts over the vehicle.
"Moments, or torque, act like a twisting force on the vehicle," explained Jeremy Pinier, research aerospace engineer in Langley’s Configuration Aerodynamics Branch.
Understanding forces and moments upon the vehicle at different wind conditions enables the vehicle to fly safely.
Engineers also used a technique for studying airflow streamlines called smoke flow visualization. Smoke is put into the wind flow and can be seen during testing. This allows engineers to see how the wind flow hits the surface of the model. "Understanding the flow patterns can give us insight into what we are seeing in the data," Pinier explained.

Today our local neighbour hood had a smoke test done.They were checking the pipes to make sure all was good and there wasn't any leaks.
Despite part of the smoke not being in the frame this is my favorite photo out of 34.
This is my first time actually shooting smoke. I had an incense stick that was in a Beer can, and that was on top of a lens case to get it off the ground a little bit. The flash was leaned against the lens case pointed up at 1/32 power zoomed out all the way.
This is also a pretty heavy crop from the original 16 Megapickle image.

Detecting hidden leaks is multi-step, complex process. With our state-of-the-art equipment, not only are we saving water, but we’re helping property owners save millions of dollars in costly property damage and destruction as well.
Leaks are more common in older properties, but newer properties are not immune to leaks either. Poor construction and other factors, including ground movement, can cause unexpected pipe damage at any time. The longer the problem goes undetected, the more likely it is to cause property damage and make repairs more costly.
Line Locators, Inc uses a combination of equipment to verify leak locations. Depending on the type of leak, we’ll use anything from infrared imaging to amplified listening devices.
Types of leaks we detect:
Domestic, Commercial and Industrial Water line leaks
Cooling and heating system leaks
Gas line leaks (hydrogen, helium, propane, natural gas)
Sewer line leaks
Swimming Pool leaks (Commercial and residential pools, Concrete/Gunnite, Vinyl liners, Fountain leaks, Spas)
Refrigeration leaks
Slab leaks
Wall leaks
Infrared leak detection
Sewer and drain leak detection
The unexpected
Our job is to locate the leak. Any leak, any kind, anywhere. We have the equipment and the expertise to find it.
Plus, we don’t do repairs, so we don’t try to sell you anything.

As part of our line detecting equipment arsenal, we now utilize the Utilivac VE75 vacuum excavation system.
The vacuum excavation method of line detection enables us to safely, and with minimal invasiveness, detect buried utilities and underground anomalies around high risk threats like plastic gas lines, fiber or high voltage lines. Vacuum excavation involves a ‘soft dig’ approach using forced air or water to loosen the soil. Then a large vacuum pump sucks up the loosened soil and gives us access to the target location.
Vacuum excavation is sometimes referred to as air knife or air knifing, pot holing, soft digging, or air spade.
This technique is often used in the environmental world to soft dig the first four feet of earth to verify there are NO utilities before the drill teams proceeds towards bedrock.

The problem with cracked pipes is that they can be difficult to diagnose and even harder to locate. That’s why at Line Locators, we are now offering the service of smoke testing. Smoke testing is a form of testing pipes that is fast, efficient, and accurate. While other pipe tests such as water testing and electronic testing have lengthy setups times and often require you to plug up your entire piping system, smoke testing can be done under normal conditions and requires nothing different. The way smoke testing works is the entire system is filled with smoke and smoke exits the pipes through any cracks, which allows our engineers to find where the smoke exits the pipeline, where gas and water builds up, and where there are any weak points in the system.
If you feel that your pipes may be cracked or damaged, Line Locators is for you! Cracks in your pipelines can be a major hurt to any home or commercial building, but you don’t have to worry about where the cracks are anymore. Our service is fast, easy, and best of all is safe. Our smoke doesn’t contain any of the toxins that many competitors use during their smoke tests. If you are in the Maryland, DC, or Virginia area and need to find out if your pipes are cracked, please contact us today!
Video Pipeline Inspection is a “no-dig” technology and one of the most versatile services Line Locators, Inc offers. By sending a specially made fiber optic camera through a line we are able to inspect hundreds of feet of pipe in a very short period of time and give our customers visual documentation of every “nook and cranny” of their system. A flexible rod with a high-resolution video camera on its tip is inserted into the pipe for inspection.
Video images are transmitted to the camera operator and can be saved onto a videotape for a permanent record. Radio transmitters on the camera record the depth and physical location from the surface so that defects and obstructions can be corrected cost effectively. Video cameras have also been used to locate lost jewelry and other valuables, as well as animals that have become lost or trapped in pipes.
If you suspect that you have a water leak behind a wall, we’ll use our highly advanced Infrared Imaging equipment to detect moisture without putting so much as a scratch on your wall.
Infrared Imaging detects a differential in temperature. This is important because you can detect the moisture before it does major damage and pinpoint its location in a non-destructive process.
Moisture in building materials can destroy structural integrity and nurture mold. The first step in moisture problem remediation is to quickly and accurately locate and remove all sources of moisture. Infrared cameras instantly show you what’s wet and what’s dry.
Infrared cameras can instantly find the ultimate source of moisture without destruction. Infrared cameras are the inspection tool preferred by building experts for fast, reliable, accurate building diagnosis in the entire range of building problems, from post-catastrophe fire and flood investigations to chronic leaks and moisture problems

Smoke & Regression tests are two crucial and different tests performed by the testing team during the Software Testing Life Cycle. However, these two are commonly considered to be synonymous, which further creates confusion among testers. Therefore, to help identify the uniqueness as well as the differences of both Smoke Testing and Regression Testing here is a detailed comparison of the two. See full article: bit.ly/2RwedaS
Warming up on the ramp before they fly. These are Chinese-built trainer planes testing their smoke machines.
Let us examine Smoke and Sanity testing -
Smoke testing essentially checks for the stability of a software build. It can be deemed as a preliminary check before the build goes for testing.
Sanity testing is performed after a stable build is received and testing has been performed. It can be deemed as a post-build check, to make sure that all bugs have been fixed. It also makes sure that all functionalities are working as per the expectations.
