Spacecraft Decelerator Testing

Long before NASA’s Perseverance Rover landed on Mars years of prototyping and testing was first completed here on Earth. Mega Speed high speed Gforce cameras were used during the initial testing and verification of the decelerator designs intended to decelerate Perseverance Rover’s high velocity space craft before landing on Mars. High speed image data was needed during the critical testing of various decelerator designs that included inflatable decelerators as well as large parachute decelerators. It would be absolutely critical that the decelerator design be able to slow the space craft down sufficiently in Mars very thin atmosphere for a safe landing.

Various Mega Speed camera models were used during these tests. Model selection was based on the test environment and the recording requirements of each individual test. Hi Gforce cameras were mounted on the rockets sleds used to propel the test items down the supersonic test track. Other camera models were used on track-side flight followers to record the test item as it passed by. Rocket sled testing was required to accelerate the test items to a high enough velocity to simulate the re-entry speed that the spacecraft would experience while attempting to land on Mars.

The above frames have been removed from the actual high speed test video from the test video related to the Mars missions.

Mega Speed DVR recorders are helping to keep you safe while flying during inclement weather

A great deal of testing and certification is required before an airplane’s jet engines are certified to fly. For the past 15 years, many of the Jet engines in service today have been ice accretion tested with Mega Speed’s high-speed DVR cameras and recorders. Ice accretion is the process where ice begins to form on the aircraft’s jet engines and wings while flying through freezing precipitation or supercooled fog. Ice accretion testing is conducted in a test facility during the winter months when conditions are favorable for ice accretion.

Destructive Impact Testing

Mega Speed high-speed impact test cameras are used by accredited government test agencies and private accredited test labs during critical component design and testing. One example application is the destructive testing of steel storage drums, which are used to store nuclear waste. A heavy steel plate is dropped onto the test article while being recorded with a Mega Speed high-speed impact test camera.

Mega Speed high-speed impact test cameras are typically used to record destructive impact tests at a resolution of 1920 x 1080 or 1280 x 800 image resolutions and at frame rates of 2000 fps to 4000 fps. These frame rates and image sizes will show the details the test engineers need to evaluate the structural integrity of the steel drum used in the storage of nuclear waste.

The above 6 picture set of frames have been removed from the actual high-speed test video to show how the structure of the steel drum performed on a millisecond time scale after a heavy steel plate was dropped on it.

Helping To Keep You And Your Loved Ones Safe

Mega Speed’s high-speed cameras are used by some of the world’s most well-known car manufacturers and component makers during critical component design and testing. One case in point is one of your automobile’s top safety features namely the airbag. The airbags in your vehicle need to precisely inflate and deflate correctly and with the correct shape to cushion your body from hitting parts of your vehicle’s interior. In order to correctly test an airbag to perform its critical life-saving task, a precise analysis must be performed during the bag’s inflation/deflation cycle.

The above 8 picture set of frames have been removed from the actual high-speed test video to show the rapidly evolving shape of the airbag on a millisecond time scale after the initial inflation was started. The high-speed video slows time down to reveal what otherwise would be impossible to see with standard video.

How to choose a high speed camera for trouble-shooting

How to choose a high speed camera for trouble-shooting ?

Are you getting ready to purchase a high speed camera but don’t quite know how to choose the correct model? No problem. Lets us try to help you and explain to you what are some of the most important things to consider before you make that purchase.

Frame Rate

Frames per second or fps, is the simple term used when describing how many video frames the high speed camera captures per each second of video. 1000 fps means the camera captured 1000 individual frames each and every single second of the recorded video. The higher the frame rate, the smoother and more detailed the video will be.

High Speed Video Recorded at 2000 FPS

High Speed Video Recorded at 850 FPS

Resolution

Higher resolutions are important when the field of view of the camera is large, or when a very small spatial resolution is required because there are a lot of fine details in the high-speed event that need to be studied. It is important to understand that the higher the resolution of the camera, the lower the maximum frame rate will be. With a 4 megapixel camera you have 4x more pixels to process than with a 1 megapixel camera. Therefore, you will not be able to achieve the same frame rates with a higher resolution camera as with a lower resolution camera. Every high speed camera has a limit on the amount of picture data it can process and store each second.

Light Sensitivity

Light sensitivity impacts your ability to use a short exposure time so that you can effectively eliminate motion blur when capturing a very high-speed event. Light sensitivity impacts the quality of your video because without sufficient light sensitivity your images will be dark and you will not be able to analyze the event in clear detail.

Analysis Software

Analysis software allows the high-speed camera to be controlled by the control computer to analyze images using distance, angle and speed measurements and output the data as reports. No one can take care or analyze high speed image data without professional analysis software. The Analysis software also allows you to precisely set the control parameters of the camera to successfully capture the high speed event. Frame rates, exposure times, trigger modes, data transfer paths and lens control all need to be controlled by the Analysis software.

Flexibility

Flexibility to choose the correct camera platform for your application.

Hand held portable cameras offer the flexibility and freedom to roam around from production line to production line problem solving as you go or they can offer the convenience of recording high speed image data at remote locations out in the field. Hand held portable cameras have removable solid state drives (SSD) and built in LED work lights for the most convenient workflow available. Hand held portable cameras also have the ability to stream longer record lengths to their SSD but at a reduce capture rate based on the capacity and write speed of the SSD.

PC connected cameras offer the flexibility to have the fastest frame rates and largest memory capacities available. They are perfectly suited for stationary applications where a PC is available to control the camera. They have the ability to quickly download the high speed image data to the control PC for review and analysis. PC connected cameras are also great for the use with high speed digital video recorders ( DVR’s). DVR’s are used for saving high speed video files for hours or days where as PC connected cameras usually have a limit of only a few seconds to a few minutes of high speed video storage. PC connected cameras typically can save at higher rates compared to a high speed DVR.

Support and customer service

Technical support and customer service is very important. Having world wide technical support available to you when you need it provides you with peace of mind for your high speed camera purchase.

High Speed Video Explained

High Speed Video Explained

Standard Speed Video Compared To High Speed Video

In today’s fast paced testing & manufacturing environment with increasingly faster and faster design cycles, diagnostics becomes increasingly difficult to do resulting in material waste and higher labour costs. The unaided human eye does not stand much of a chance visualizing what part of the process is causing all the problems. The use of a high speed camera during set up, maintenance or research design will reduce downtime and greatly improve efficiency, product quality and profitability in any process that involves drop tests, design verification, prototype testing, vibration analysis or quality control.

Why use high speed video?

Standard 30 fps (frames per second) video can only provide a few images of a rapidly occurring event. The images are too few and always blurry due to the fact that the camera’s shutter speed can not be precisely controlled to eliminate high speed blur. We can all relate to how fast an air bag inflates. Most of the event is missed with a normal camera or the unaided human eye.

Air Bag Sequence Recorded With Standard Video

Air Bag Sequence Recorded With High Speed Video

The above high speed video will provide you with 50 to 100 times more images of the same event so that you can clearly see what the problem is during your research and development.

High Speed cameras can generally be manufactured in one of the following two ways:

Capture high frame rates, usually between 250 – 5000 fps for shorter durations of time from 10 to 120 seconds. These types of cameras have internal SDRAM and the user downloads the video after the event is recorded.
Capture lower frame rates, usually between 120 and 1000 fps for longer durations lasting several hours. These types of cameras have no Internal SDRAM. They stream the live video to the DVR PC’s hard drive.

With most high speed cameras, there will always be a trade off between frames per second, resolution and record time.

High Speed Camera Options

PC Connected

MS55K-SC/MS100K-SC

MS55-SC-HG/100K-SC-HG

MS120K

MS130K/MS140K

PC Connected cameras have internal SDRAM for fast file saving. They send back a live preview to the PC at 30 fps while the high speed video is saved in the camera’s internal SDRAM in a circular buffer to be downloaded later. These cameras require a Gigabit Ethernet connection to a PC for control and download. They can be a bit lower cost than an equivalent “Hand Held” camera but are not as portable and must be connected to a PC with a Gigabit Ethernet connection.

Hand Held Portables

Hand Held Portable Cameras are completely portable and do not require a Gigabit Ethernet connection to a PC to be operated. They have internal SDRAM for fast saving, built in Solid State Drives for file storage and offer a live preview screen. They also have a large touch screen display and also have built in high power work lights to prevent image blur during low exposure setting. As an added feature hand held cameras can also be connected to and controlled by a PC with a Gigabit Ethernet connection in the same way as the above PC connected cameras.

PC Connected DVRs

DVR Cameras have no SDRAM inside. These cameras stream video data back to a DVR PC in real time. These cameras are similar in function to our other high speed cameras except that they are designed to record high speed video for hours or days at a time. These types of cameras / DVR’s are used on your production line or at your testing station to record problems when you are not there. They will record and save every minute detail, allowing you to quickly look back in time to diagnose the problem. You may also tie this system into your control logic to automatically record and save files of special interest. These types of cameras are used to record infrequent production problems or to archive your entire process over an extended period of time.
