DESIGN NAME: Falcon Blade (Gladius)
PRIMARY FUNCTION: Cricket Bat
INSPIRATION: The poor performance of Indian cricket team in the 2011 test series vs England and Australia. The batsman were not able to put up a fight because of the conditions. We saw a lot of dismissals of players getting out in the slips. We as engineers thought can the design of the bat be changed to prevent the ball to reach the slips. Once the problem was identified, it took us 4 design iterations to optimize the design.
Our motives are to have professional cricketers at all levels use the bat.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: The bat has a better aerodynamic profile which allows it to cut through the air faster. Additionally the direction of force impacting on the ball in case of an edge changes reducing the chances of getting out on the slips.
OPERATION / FLOW / INTERACTION: The Falcon Blade is operated manually, very similar to the normal bat. In the Falcon Blade, the edges are modified to provide an aerodynamic advantage while hitting a ball. The trajectory of the ball after hitting the edge is changed in such a way that the chances of getting caught out, specifically in the slips/keeper, reduces.The key frames of this system are the type of shot being played and the velocity of the ball when an edge is hit by the bat.
PROJECT DURATION AND LOCATION: The project was started in 2012 in IIT Bombay, Mumbai and finsihed in 2014 in Mumbai.

PRODUCTION / REALIZATION TECHNOLOGY: The motive of the design was to impart add direction of force to the ball when it hit the edge. In order to impart this additional force an introduction of a 3D taper was chosen. The constraints such as not being able to reduce the face of the bat and insignificant change in the direction of force were accounted for. The final dimensions and the equation of the 3D taper curve were determined.
A mold was created based on this equations. This mold is placed on the face of the bat and the remaining wood the bat is shaved off meticulously to give the desired design to the bat.
Material is same as compared to a normal cricket bat available in the market i.e wood.
SPECIFICATIONS / TECHNICAL PROPERTIES: Width x depth x height = 108mm x 50mm x 840mm
The height is 550mm of the bat face and 290 mm of the bat handle.
The 3D taper is only present on the face of the bat. It starts at one corner of the face (assume that to be the origin) and goes till a width of 10mm and a height of 220 mm. From this maximum point it again goes to the corner of the bat. This same curve is replicated symmetrically.

RESEARCH ABSTRACT: A detailed collision analysis was done using ANSYS, to study selected shots like forward defense, square cut and cover drive. Initial conditions were put in to simulate actual shot playing condition and data collected was analysed. Simulations were done for this design and a standard bat, and a data comparison was done. Drag and pressure variations were studied in FLUENT. Actual field testing in practice and in an actual match scenario. data collection- field report .
The research proved that the design for the bat which has been used in the past 100 years was not optimized in an aerodynamic perspective.
Business aspect :The current design can be incorporated in any bat and an upgraded version can be created. This would lead to newer designs of bat for brands to sell. Also since this is a retrofitting modification even the bats which are in the market can be modified into this, thus the market size is even greater.
The direct impact of the research would be in the game of cricket itself with international players using this to their benefit. MCC(Marylebone Cricket Club), who operates a museum,archives and library of cricket have also asked for a copy of the design to be kept at their archive, so that future generations can see the evolution of the cricket bat.
CHALLENGE: Bats have been historically becoming bigger and broader. Players expect that bigger and broader bats are better in terms of hitting the ball with more power. Our design was counter intuitive to this notion, since we actually made the bat narrower by shaving off the portions which is not used for attacking purposes.
The hardest part of the design activity was pursuing the research on this design which is counter intuitive to the trend of the cricket bat. During test runs, when the bat was presented the batsman, there was a psychological hindrance, however once they were convinced of the design, they used the bat for trials. After the trails they agreed that this design only makes their game better.
MCC is the governing body for laws of cricket. A sample of the bat was sent to them for approval. In march 2014, the design was approved making it legal to be used for all the formats of the game of cricket.
