TRIALSAPP

TrialsAPP TrialsAPP

Accurate acquisition, analysis and recording of data during vessel seatrials has become even easier with CJR’s TrialsApp. The system developed by CJR consists of a lightweight, portable tablet with high performance Android software, which analyses crucial data collected by wireless sensors.

 

Following on from the success of the laptop based data acquisition system TrialDas, TrialsApp is sold by CJR as a complete package, which includes a high performance Android tablet preloaded with the App, 3 x wireless vibration FFT / sound level sensors, 2 x optical rpm sensors for measuring shaft speed, GPS for boat speed and 3 x axis gyroscopes for measuring vessel running and heel angles and turning circles. The system can also be tailored to suit a client’s needs with the addition of other sensors such as temperature, pressure etc.

The system is very easy to set up and produces real time reports in pdf format which can be viewed before the yacht has returned to shore without the need for in depth interrogation of the data.

TrialsApp provides an even easier and more affordable, highly accurate means of recording all aspects of a vessels performance during sea trials.

  • Design

    We don’t only make propellers, we analyse entire propulsion system of each boat starting from hull resistance prediction and hull propulsive factors.

  • Pattern Making

    Precise pattern assures high accuracy of final product and it is one of the most important stages in manufacturing process

  • Casting

    CJR's foundry team has the combined benefits of over 150 years experience in the industry.

  • Machining

    CAD/CAM controlled machining of the cast propellers, P brackets and rudders are undertaken to the fine tolerances of their original design

  • Finishing

    Our processes ensure that the geometry of our finished castings is always true and accurate to the original design.
