Dudek Reaction

 

dudekreaction


After research ReAction was improved, so to distinguish it from the original, Dudek changed both name and logo of the wing to a Reaction TST.


ReAction TST features our Tip Steering Toggles system, designed to facilitate high speed flying. The risers have been modified and a scheme of split A's was introduced, so that smooth inflation can be obtained much easier. Previous arrangement sometimes caused the wingtips to shoot up earlier than the centre, but now the margin for pilot error has been considerably widened.


ReAction is an technically improved and graphically renewed version of Action. It is based on the same proven reflex-wing concept. It features a self-stabilising wing section that, in the case of a decrease in its angle of attack, automatically responds to compensate, so it's tuck-resistant.


In comparison to its predecessor, the ReAction is a bit faster, inflates easier and features a number of changes that improve wing durability and ease of use. The ReAction 'S' version is equipped with non-sheathed lines in the upper rigging.


The most significant changes in the Reaction TST are:
- smoother trailing edge and overall better profile projection.
- risers have new trimmer buckles and exchangeable trimmer tapes.
- risers now have two suspension points to choose from (low and high, depending on pilot's harness/engine setup).
- the magnetic clips of the brake handles have been improved.
- internal ribs and suspension points have been strengthened, making the wing even more durable.
- the suspension line layout has been modified at the central part of the trailing edge.
- n the 'S' version all upper gallery lines are made of non-sheathed Dyneema (overall drag reduction).
- new set of colour schemes for the wing


ReAction has passed the AFNOR Performance certificate.


The 'S' version has passed additional strength tests due to the different kind of lines.


The smallest and biggest ReAction sizes passed the CEN/AFNOR tests, where both qualified as Performance class. The 27 and 29 sizes obtained a double qualification (Standard/Performance).


On ReActions 25 and 31 the test pilots managed to induce the frontstall with fully closed trims, something very hard to do in normal state of flight and practically impossible to happen on its own. The forced frontstall that occured was much deeper than in normal aerofoil wings, and because of that it opened longer than three seconds. That was the only reason for the Performance rating - in all other manoeuvres our ReAction conformed with the Standard class.


In open trims configuration Performance rating was caused by the B-stall.
