Daily Test Logs - Week 2 - March 1 to March 4
Test logs are created by the Test Manager (Pete Zell) each day that a test is "in the tunnel". Entries in the test logs are made when important events occur, when tasks are completed and when milestones are accomplished. S ometimes entries are made once every couple hours, sometimes once per hour, and sometimes with only minutes in between - it all depends on what's happening with the test! At the end of the day, Pete lists the tasks that we plan to do the following day. The log is posted on a computer network so that anyone at Ames Research Center who is interested in the progress of the test can get up to the minute information about what is happening. At the end of each day, we will post a summary of the daily test log on this webpage so that you, too, can track the progress of the test!
March 1, March 2, March 3, March 4 See photos from today's work!! Summary: We completed setting the roll stops and alpha and beta weight tares. We ran into a problem with the motor power system and couldn't complete the propeller check out that we wanted to. We decided to wait until Monday to perform thrust tare and first wind on run. Rich and Mike worked until 22:30 on instrumentation. Log:
Plans for Monday: General
Today is Media Day! We had about 20 media groups visit and we did about 12 live feeds in the afternoon. The local affiliates of FOX, NBC, and ABC were here as well as local channels KNTV and 66. National groups included CNN, API, CNET and ABC Discovery. Press groups included AP and UPI. A great day for showing off the Flyer!! After 17:00 we had some time to perform check loads on the balance. The applied weights matched the balance output very well. We repaired the RPM sensor - a diode behind the display in the control room was reversed. We are all set to run on Thursday with two exceptions. We must set the roll stops and perform the Test Readiness Review #2. The roll stops need some rigging setup. I will leave a sketch on Paul Askins desk. Please pull together the rigging if you have some time in the mroning. Lew Mermelstein plans to look for the source of a foul that is being observed in the control room from the floor balance. This foul is not an issue for the Wright Flyer because we are using an internal balance, but we would still like to know the source. We have a tour of the Astronaut Class of 1998 at 11:30 tomorrow. Thanks to everyone who worked so hard to make our Media Day such a success. Hopefully we can now focus on getting some good data for our customer. Note that we will not be running on Friday and that we plan to go to swing shift next week. Our shift will be 15:00 to 00:30. Plans for tomorrow: Mechanical

See photos from today's work!! We accomplished a great deal today! We completed model installation and most of our systems checks. The balance signals were restored when a bad cable was found in between the model and our balance house connector box (under the floor of the tunnel). We also installed a floor camera and light in order to view the underwing tufts. (Thanks Paul Askins and Rob Fong!). We ran the motor drive system up to 60 rpm and confirmed correct propeller rotation direction. We plan to run the drive train at this condition during part of Media Day tomorrow. The rpm indicator we installed on the drive train is not working. Several wiring repairs were attempted but still no go. The tunnel has been prepared for Media Day tomorrow. Bring on the cameras and reporters! Mike MeWhinney confirmed that we have several morning and afternoon news crew confirmations. This morning we were on Good Morning America. 2 and 1/2 minutes of air time for hours and hours of preparation! Charlie Gibson and Diane Sawyer seemed impressed! Our plans are to run on Thursday. We have been given a list of our first series of runs by the AIAA team. Plans for tomorrow: Mechanical

See photos from today's work!! Our goal for today was to mount the Flyer on the sting. This objective was accomplished. We also completed control surface calibrations, the installation of an rpm sensor, and the modification of wing tufts. Crew training was conducted. During installation of the model on the balance we experienced a problem with one of the balance amplifiers. This problem was traced to a bad amplifier for roll and a questionable amplifier for one of the side force gages. We decided to land the model (that is, mount it on the sting) and use the lift gages for a weight measurement. Repairing the amplifiers is high priority for tomorrow. Note: Good Morning America will be filming the Flyer at 05:45 tomorrow! Plans for tomorrow: Mechanical
