Future Supersonic Aircraft With No Sonic Boom – Noise Cancelling or Noise Suppression?

Well, over the last few months I have returned to the subject of silent flying aircraft. Back in 2000, I hypothesized many different strategies for creating aircraft which make no noise – even jet aircraft which could cancel out a sonic boom, and prevent any of the jet turbine noise from waking people up as they took off over the city. This future reality is coming to fruition very soon, that is to say future supersonic aircraft with no sonic boom. Indeed I’d like to discuss this with you for a moment if you have the time.

Recently, there was an interesting piece on this topic, as Gizmag online had a cool feature recently titled; “Futuristic Biplane Design Eliminates Sonic Boom,” by James Holloway, published on March 19, 2012. The article with artist’s conceptions stated;

“A first boom is caused by the rapid compression of air at the front of the plane, literally pushed together by the aircraft. A second is caused by the negative pressure left in the plane’s wake – or rather, the rapid return to normal pressure that follows soon after. Though the two booms separate phenomena, they occur so close together that they are usually perceived as a single sound. An aircraft in supersonic flight creates a continual boom as it goes.”

If you go to the MIT Media website and search for this press release: “A biplane to break the sound barrier – Cheaper, quieter and fuel-efficient biplanes could put supersonic travel on the horizon,” by Jenifer Chu published on March 15, 2012 you can read all about it.

Well, a dual swept flying winged biplane which was properly aerodynamically configured could indeed accomplish this. It’s not that the sonic boom would go away rather it’s that the sonic boom could not escape, and that sound could not travel to other people in ear shot. Would it costs too much to build an aircraft like this; perhaps not because instead of one large wing, it would have two smaller ones. In fact, it is a decent design for efficiency on the flight ramp due to its short wing span, and if scaled down, it might even make a nice little fighter aircraft. Scaled up of course, it can be used for a corporate business jet or even an airliner. Perhaps even in an air cargo aircraft configuration.

There seems to be many ways to solve this problem of trapping a sonic boom, or using noise canceling strategies. This is merely one, and although this aircraft may never be built, it does include some rather ingenious and creative thinking. Perhaps one should be built, or several as prototypes for no other reason than to see what we can learn. Indeed I hope you will please consider all this and think on it.

Sonic Drive-In – One of the Top 25 Franchises

Sonic Drive-In is an iconic American fast-food restaurant chain noted for its retro theme, affordable food and curb-side service. Created in 1953 in Shawnee, Oklahoma, what begun as a simple hamburger restaurant called Top Hat Drive-In has since transformed into the enormously popular fast-food chain that offers good food at low prices. The curb-side service, reminiscent of the 1950’s, is another reason why this restaurant has such a wide appeal across the country. Today over 3,500 Sonic Drive-Ins can be found in most states all across the United States, making Sonic the largest drive-in franchise.
 
Sonic is a very successful franchise that operates drive-in restaurants with the wildly popular pull-up, curb-side service that has made the chain famous. On the menu is a variety of made-to-order fast-food items (Tater Tots, fries, hamburgers, and desserts), most notably their signature Toaster sandwiches (sandwiches made with Texas Toast) and Extra-Long Cheese Coneys. They are also famous for their Happy Hour every day that offers any drink – even their flavored Fountain Favorites- half-off from 2pm to 4pm. The prices are what offer the most appeal and benefit to the consumer; the affordability of the product (noted especially with the cheap drinks during Happy Hour) along with the ease of service makes Sonic beneficial to the average family. Sonic is also attractive to investors due to the large size, great stability, and very successful marketing strategy of the chain.
 
When it comes to fast-food in the United States, few franchises match Sonic in terms of food quality, service, and value. The charming setting combined with the successful marketing campaign, affordable food, large scale, and widespread availability of the chain makes Sonic a worthwhile investment if you have 1.2m-3.2m to totally invest this just may be the franchise for you. If you want employee’s and to be away from home all the time! However, for those of you that are more like me, there are other means of owning your own business with less of the liability of a large franchise.

What Is the Best Sonic Toothbrush?

Sonic toothbrushes have become extremely popular over the years. They were first introduced to the market in 1983 by Sonicare. Since they were released, the heads and vibration technologies have advanced dramatically. If you are shopping for a sonic toothbrush, chances are that you want to find the best one on the market. Before you start shopping for a sonic toothbrush, you need to understand that not all electric toothbrushes are classified as sonic toothbrushes. An electric device will vibrate at speeds of 3000 to 8000 strokes per minute. A sonic toothbrush on the other hand will operate at 30,000 to 40,000 vibrations per minute. As you can see, there is a major difference in the efficiency of cleaning. Learn what features to look for when you are shopping for your oral hygiene tool.

What is the Best Product You Can Buy?

There are so many different models on the market that choosing the best model can be extremely difficult. The first thing to look for is a vibrating head. Some heads only move back-and-forth and others will vibrate. Vibration will loosen the food and plaque. Consider the speed at which the toothbrush vibrates and look for adjustable speeds so you can get familiar with the feel when you are first using the model.

You should also look for other features like a timer. A timer can be helpful for people who rush their brushing sessions. When you live a busy life, the idea of brushing for 2 minutes may sound too long. It is imperative to brush for 2 minutes so you thoroughly clean all of your quadrants. With a timer, you will be alerted when you have reached that 2 minute mark.

You should look for a brand that comes with several different head options. You might want a soft-bristled brush or a medium bristle. You might need a smaller head because you have a small mouth. Make sure you can choose what is comfortable for you and look for brush heads that are not too expensive to replace.

Some of the more expensive brands come with advanced features that are designed to make use easier. You might want a rechargeable battery or a docking station. Consider your budget and the features you will really use. If you choose the best model for you, you will see less plaque when you floss and your dentist will give you a clean bill of oral health.
