Which vanes

Some vanes are really fussy and only like one single type of glue. A lot of manufacturers will coat the feet of their vanes in a chemical activator or accelerant. Quite often these will be formulated to work with their own brands of adhesive which are usually CA Cyanoacrylate based.

In order to use a MEK adhesive on a CA prepared vane the foot has to be thoroughly cleaned with alcohol or acetone. Do a little research into chemical compatibility long before making a purchase. I often get asked if a great all-round vane exists. Personally I think that it does. These vanes offer a good mix of speed and stability. The smaller sizes going up to 2. The larger sizes have been used to great effect indoors.

They have proved to be ultra durable and have an excellent foot design for bonding purposes. They will also work well with a lot of different glue brands and types. This is down to the fact that designs are constrained by the laws of physics and aerodynamics. That said there have been some exciting new models come to market in the last few years. Two that spring to mind are are the Dragonflight vanes from Bjorn Bengtson and the Griffin vanes from Bohning.

The Dragonflight vanes are a radical segmented design. The segments offer increased surface area allowing for a shorter vanes to be used. The design is also very forgiving in terms of bow clearance. Exhaustive testing has shown that a three vane configuration is the most effective. It provides enough stabilisation to control both yaw and pitch motions. An excellent analogy is the tail of an aircraft.

This controls the horizontal and vertical motions whilst maintaining sleek aerodynamics. Adding more vanes into the equation would increase the control surface area and stability level, but it would also impart more drag.

Increased drag would have a negative effect on sight marks which is normally a consideration for most recurve shooters. Having more than three vanes can also lead to encountering bow clearance issues. A four or six fletch configuration would limit such airflow. As with most technical aspects of archery what we gain on one hand, we lose on another. The vanes are designed to be placed with a small offset for maximum efficiency.

These have found a lot of favour with field archers due to dealing well with crosswind drift. They also look pretty amazing and are instantly recognisable. Griffin vanes are a revolutionary twisted ribbon design. There are a range of Symbols that can be used to represent Vane Pumps in Process and Instrumentation Drawings - learn more.

What is Vortexing? What Are Vane Pumps? View our vane pump animation Vane pumps are reversible which makes them an excellent choice for stripping and unloading tanks. Belt Driven designs can eliminate gear box ATEX rated for handling of flammable liquids Can not handle solids or abrasives Heating chamber allows solidifying liquids to be kept at low viscosity and prevent solidification within the pump Limited viscosity handling compared to other positive displacement pumps - maximum of 10,cst High Suction lift capability and can Self Prime up to 8M Reversible meaning pump can be used to load and unload tankers, but also ensure product is fully recovered from hoses.

Flow rate is largely unaffected should back pressure or pressure losses change. Other pump types lose efficiency as they wear Multiple sealing options from Single Mechanical Seal, double mechanical seal and gland packing ensures suitability for a wide range of liquids.

Gear pumps can have bearing or bushings in contact with fluid which can cause bearing lubrication issues with low lubricating fluids Liquid ring pumps do not have as many sealing options.

VP are self-priming by design. Gear pumps are more precise for dosing or metering VP typically have a lower NPSH requirement VP do not have metal to metal contact allowing pump to prime from dry but also strip containers, and handle non lubricating liquids Gear pumps can have timing gears significantly increasing cost and meaning maintenance is more difficult VP self compensate for wear.

VP have lower vibrations Centrifugal pumps can have impeller design changed to handle solids, or abrasives. VP have limited high viscosity handling 10,cst vs gear of 55, cst There are a range of Symbols that can be used to represent Vane Pumps in Process and Instrumentation Drawings - learn more.

These are the all round choice. Most arrows you buy will come pre-fletched with plastic vanes, and replacing them is easy. If you're not sure what to buy, plastic is always going to work well. They're probably the best all round frame you can buy. The most popular style of vane. Easy to glue onto an arrow. They can be cheap, easy to use and hard wearing. There is a great selection of colours, patterns and sizes. There is a vane to suit just about any situation. Popular with compound archers for indoor or outdoor use.

You can use a smaller vane for faster speeds, or pick a bigger one to slow things down. So what are spin or mylar vanes? They are flexible, thin, plastic vanes that have a built in twist.

One of the most well know brand is Spin-Wing. These are very popular with recurve archers shooting indoor or outdoor. They are small, light and easy to replace.

They are specially designed to spin and stabilise the arrows quickly, and being very light will not affect the arrow speed very much. These are the most engineered of all the vanes available. A lot of research has gone into making them, to ensure you have the best arrow performance you can get.

They can be quite fragile and will need to be replaced quite frequently. In the case of profiled propeller vanes, the thickness distribution along the median line in accordance with hydrodynamic factors plays a major role. The minimum vane thickness is approx.
