Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Rocket Sled shopping experience:
1. Compare - without doubt the biggest advantage that the Rocket Sled offers shoppers today is the ability to compare thousands of Rocket Sled at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Rocket Sled? Wrong! If the Rocket Sled is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Rocket Sled then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Rocket Sled? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Rocket Sled and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Rocket Sled wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Rocket Sled then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Rocket Sled site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Rocket Sled, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Rocket Sled, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.
rides the rocket sled at Edwards Air Force Base.
A
rocket sled is a test platform that slides along a set of rails, propelled by
rockets. They were used extensively by the United States early in the Cold War to accelerate equipment considered too experimental (hazardous) for testing directly in piloted aircraft. The equipment to be tested under high acceleration or high airspeed conditions was installed along with appropriate
instrumentation,
data recording and
telemetry equipment on the sled. The sled was then accelerated according to the experiment's design requirements for data collection along a length of isolated, precisely level and straight test track.
Testing
ejection seat systems and technology prior to their use in experimental or operational aircraft was a common application of the rocket sled at
Holloman Air Force Base. Perhaps the most famous, the tracks at
Edwards Air Force Base were used to test missiles, supersonic ejection seats, airplane shapes and the effects of acceleration on humans.
As its name implies, a rocket sled does not use wheels. Instead, it has sliding pads, called "slippers", which are curved around the head of the rails to prevent the sled from flying off the track. The rail cross-section profile is that of a
Vignoles rail, commonly used for railroads. Once the sled achieves sufficient speed, the slippers are suspended above the rails by a thin film of air, essentially creating a
fluid bearing.
Unmanned rocket sleds continue to be used to test missile components without requiring costly live missile launches. A Land speed record for railed vehicles of Mach 8.5 (6,416 mph / 10,325 km/h) was achieved by a four-stage rocket sled at Holloman Air Force Base on April 30, 2003.http://www.af.mil/news/story.asp?storyID=123004755
Murphy's law first received public attention during a press conference about rocket sled testing.
The rocket sled track at Edwards Air Force Base was dismantled and used to extend the track at Holloman Air Force Base. The Holloman Sled track is almost 10 miles long with that extension.
