This list is titled as "Incomplete", as there are many aircraft that are still not included. I established a "wanted list" of aircraft whose airfoil designations I am still looking for. If you have airfoil designations for any of these aircraft, please e-mail me at: dave lednicer. A note: this list has grown to the point where it is quite large. For this reason, it takes a while to load. I apologize for the inconvenience but assure you that the wait is worth it!

On designations: many of the airfoils listed here have "mod" at the end of their designation. Typically, this means that either the camber line has been modified, the leading edge contour has been modified or that the trailing edge thickness has been changed. Some common airfoil name prefixes and their designers are:. Peter Lissaman of AeroVironment Inc. MAC - Airfoils designed at Mitsubishi.

During the s, the designer was Tsutomu Fujino. TH - Dr. Jane's All The World's Aircraft has been a good source of this information, but in many cases particularly military aircraft it doesn't list this information. To answer this perennial question, the following list has been created. Besides conventionally configured aircraft, canard configured aircraft, tandem wing aircraft, three-surface aircraft, helicopters, tilt rotors and autogyros are addressed.

According to the NASA website:. During the late s and into the s, the NACA developed a series of thoroughly tested airfoils and devised a numerical designation for each airfoil — a four digit number that represented the airfoil section's critical geometric properties. ByLangley had developed this system to the point where the numbering system was complemented by an airfoil cross-section, and the complete catalog of 78 airfoils appeared in the NACA's annual report for Engineers could quickly see the peculiarities of each airfoil shape, and the numerical designator "NACA ," for instance specified camber lines, maximum thickness, and special nose features.

These figures and shapes transmitted the sort of information to engineers that allowed them to select specific airfoils for desired performance characteristics of specific aircraft. The NACA four-digit wing sections define the profile by: [2].

The NACA airfoil is symmetrical, the 00 indicating that it has no camber. The formula for the shape of a NACA 00xx foil, with "xx" being replaced by the percentage of thickness to chord, is [4].

If a zero-thickness trailing edge is required, for example for computational work, one of the coefficients should be modified such that they sum to zero. Modifying the last coefficient i. The leading edge approximates a cylinder with a radius of. The simplest asymmetric foils are the NACA 4-digit series foils, which use the same formula as that used to generate the 00xx symmetric foils, but with the line of mean camber bent.

The formula used to calculate the mean camber line is [4]. The NACA five-digit series describes more complex airfoil shapes. For example, the NACA profile describes an airfoil with design lift coefficient of 0. The camber line is defined in two sections: [10].

The camber line is defined as [10]. Camber lines such as makes the negative trailing edge camber of the series profile to be positively cambered. This results in a theoretical pitching moment of 0. Four- and five-digit series airfoils can be modified with a two-digit code preceded by a hyphen in the following sequence:.

In addition, for a more precise description of the airfoil all numbers can be presented as decimals. A new approach to airfoil design pioneered in the s, in which the airfoil shape was mathematically derived from the desired lift characteristics.

Prior to this, airfoil shapes were first created and then had their characteristics measured in a wind tunnel.Sign in Sign up.

The equation for the camber line is split into sections either side of the point of maximum camber position P. In order to calculate the position of the final airfoil envelope later the gradient of the camber line is also required. The equations are:. Using the equations above, for a given value of x it is possible to calculate the camber line position Yc, the gradient of the camber line and the thickness.

The position of the upper and lower surface can then be calculated perpendicular to the camber line. The most obvious way to to plot the airfoil is to iterate through equally spaced values of x calclating the upper and lower surface coordinates.

While this works, the points are more widely spaced around the leading edge where the curvature is greatest and flat sections can be seen on the plots. Airfoil Tools Search airfoils Tweet.

Airfoil database search (NACA 4 digit)

But even if label printers are taking on digital label printing, so are the print shops, commercial printers, converters, contract packers, manufacturers and brand owners themselves. The commercial printers have at least 20 years of experience in digital printing, and they know exactly what it takes to integrate new processes. They already serve the brand owners with printed materials, so why not labels too.

Converters, contract packers and manufactures are all handling various complex processes on a daily basis, and, of course, they can press the print button of a digital label press. What they might not know is how to prepare the digital files and how to ensure color matching, and maybe there lies an opportunity.

What if the label printer provided their customers with distributed printing facilities. What if each customer had its own digital label printer for small runs provided by their label supplier. The label supplier takes care of material supply, installation, maintenance, training, file preparation and color management, as well as enables the customer to print small individual batches whenever this is required.

This might be a way for them to cling on to the customer and the huge productions that they will still need from time to time. We see an increasing demand from brand owners and manufactures to have in-house label printing equipment to serve their need for small batches, variable data and just-in-time production.

And I believe that the only way the label printers can stay in the game is to figure out how they can contribute to that trend. The complexity in the supply chain needs to be managed efficiently. Peanuts or Mondelez or Budweiser featuring HP SmartStream Mosaic software. With more regulations driving for up-to-date, accurate product labels (such as ingredient lists) and the operational advantages of high-capacity digital production we expect this trend to increase in 2017. Going into 2017, we are seeing more and more embellishments, and even the first demonstrations of embellishments done digitally.

At drupa 2016, we demonstrated the first step towards an HP Indigo Digital Combination Press, which is designed to, through a single file and point of control, print both the label and the embellishments in an end-to-end digital line. It must be said that not all the trends we anticipated in the past few years reached their tipping point. One example is security features.

We believe there is a very real need for these in the market, but we still have not seen widespread adoption of features that make full use of digital printing capabilities for security purposes, tracking and brand protection purposes. This is one area for which we see huge potential in 2017 and beyond. All of these are posed to helps brands and converters further differentiate through unique, top-quality products that will spearhead the label industry for years to come.

As a result, Memjet partners created a greater diversity of solutions that increase the capability and affordability of solutions for this market.

Growth of these types of solutions will continue to grow in 2017. We expect to see significant demand from flexo printers for retrofit digital inkjet solutions. Because these solutions utilize existing capital infrastructure, providers are able to add digital capabilities at a low cost of entry.

An example of this is the Colordyne 3600 Series Retrofit, which is now also being sold by Mark Andy. More growth will come from solutions that combine multiple applications in one system. The demand for inkjet solutions and this high level of product innovationwill continue into 2017 and beyond.

Year in and year out, growth continues at around the five percent mark and it is the objective of all market players to exceed this organic growth rate by exploiting their particular competitive advantage. Thermal transfer technology is now 30 years old and has reached maturity, yet still offers advantages that cannot be equalled: it is economic, reliable and clean.

Today, low-cost operators are gaining a solid foothold in our industry but, as is always the case, they will quickly come up against their own limitations. You just have to offset the anticipated gain from the printed label against the constraints and risks incurred: the outcome is clear and is a simple matter of common sense. At the end of the day, quality and service will come out on top whenever the solution is coherent, appropriate and offers a high level of performance.

All of Armor's most recently established transformation subsidiaries (India, Mexico and South Africa) confirm the value of proximity by producing remarkable penetration rates, and this is only the start.If the objective field has missing values at its tail, then this adjusted value will differ from the one specified or computed from start and interval.

If you do not specify an objective field, BigML. Once a time series has been successfully created it will have the following properties. Each field's id has a list of objects with the following properties: The property forecast is a dictionary keyed by each field's id in the source.

Each field's id has a list of objects with the following properties: In addition to the ETS models, BigML also provides simple forecast models for each field, to be used as references for the performance of the ETS models. Due to their trivial nature, these are always computed regardless of what ETS parameters are selected in the input. Currently, we offer three simple model types: naive, mean, and drift. Naive: this model always forecasts the last value of the observed time series.

For seasonal models, it repeats the last m values of the training series, where "m" is the given period length for the field. The parameters for this field are as follows: Mean: this model always forecasts the mean of the objective field. For seasonal models, it is similar to the naive model since the model cycles the same sequence of values for forecasts, but instead of using the last set of m values, BigML computes the mean sequence of the naive values.

The parameters for this field are as follows: Drift: Draws a straight line between the first and last values of the training series. Forecasts are performed by extending that line. The parameters for this field are as follows: Creating a time series is a process that can take just a few seconds or a few days depending on the size of the dataset used as input and on the workload of BigML's systems. The time series goes through a number of states until its fully completed.

Through the status field in the time series you can determine when time series has been fully processed and ready to be used to create forecasts. Thus when retrieving a timeseries, it's possible to specify that only a subset of fields be retrieved, by using any combination of the following parameters in the query string (unrecognized parameters are ignored): Fields Filter Parameters Parameter TypeDescription fields optional Comma-separated list A comma-separated list of field IDs to retrieve.

To update a time series, you need to PUT an object containing the fields that you want to update to the time series' base URL.

Once you delete a time series, it is permanently deleted. If you try to delete a time series a second time, or a time series that does not exist, you will receive a "404 not found" response. However, if you try to delete a time series that is being used at the moment, then BigML. To list all the time series, you can use the timeseries base URL.
