AEROSPACE 305W RC Helicopter Experiment Simple vs. Detailed LabView Acquired Data
Assignment Prompt:
“Please send me one technical memo from your group that documents the experiments conducted during lab to determine the small RC helicopter performance. In addition, compare your results in your memo to the “simple” experiment conducted in February 2021.”
As a group, you have been asked to measure the lift force and rotational rotor speed of a small RC helicopter, while varying the input power. During lab, you will collect, and process detailed voltage data acquired by LabView, and use it to calculate lift force, rpm, torque, and power. You will then compare your processed data to the data collected in February 2021 that is provided on CANVAS in the PPT file named “Simple Helicopter Experiment”. Experiment design considerations:
The following questions should help guide you with writing the “introduction” and “discussion” of this experiment.
How useful was the "simple" data compared to the LabView acquired data?
Was it possible to measure all quantities simultaneously using the "simple" tools?
What is the input power and control used during each experiment?
What is the observed repeatability between ALL
experimental data?
Are there any physical effects that have been unaccounted for in these experiments? Documentation: Your group memo should include at least the following information.
Memo header and memo section headings described in the “writing” lectures.
Complete wiring diagram of the experimental apparatus.
A photograph of your experimental apparatus.
A short description of the procedures and working principle of your apparatus.
Graphs demonstrating the relationship between Lift, RPM, Torque, and Input Power
Discuss the differences between the "simple" and LabView acquired data.
Be careful to use the same units when reporting the various sets of data.
Comparisons should be made by overlaying multiple sets of data on each graph.
As for the parachute memo, report uncertainty and % error information in your “Conclusions” and show your work for these calculations in your “Appendix”.

You are assigned as the head of the engineering team to work on selecting the right-sized blower that will go on your new line of hybrid vehicles.The fan circulates the warm air on the inside of the windshield to stop condensation of water vapor and allow for maximum visibility during wintertime (see images). You have been provided with some info. and are asked to pick from the bottom table, the right model number(s) that will satisfy the requirement. Your car is equipped with a fan blower setting that allow you to choose between speeds 0, 1,2 and 3. Variation of the convection heat transfer coefficient is dependent upon multiple factors, including the size and the blower configuration.You can only use the following parameters:

Question 2
You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture
fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates
implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial
weight bearing activities.
Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to
verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into
solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending
test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the
yield stress for the…

Analysis and Interpretation of vertical Ground Reaction Forces. In this study, a volunteer was asked to walk on two force platforms under two different conditions. Condition 1- Normal Walk (NW), condition 2 - walking over an obstacle (ObsW). The right limb was the one to step on platform 1 in both conditions. The force platforms were used to measure the vertical ground reaction forces on the right limb. Data was collected on Vicon (Nexus) software and the attached graphs ( mean NW/ObsW, Mean (+-)1SD NW/ObsW) were created. Analyse ,Interpret the graphs and make a conclusion of the result attached.
