This consists of: Spending time practising on the simulator and training with a real pilot on a trainer plane. Trainers will be available Tuesday and Thursday mornings at 8am (I know its early, but this is the only time that Johnson is free). If you want to train on either of these days, you must email me, and I will contact the training pilots. By telling me you want to train on a day, you are committing to be there (the training pilots are volunteering their time, so be nice to them). You can fly on your own once the training pilots have cleared you to do so. The reasons for these precautions is the general lack of spare parts, and if you crash your Dragonfly, you might not be able to fix it. Once you have built your dragonfly, please have Col Young check it over before taking it flying to make sure that everything is working properly. Good luck flying, -Howie From chipd at MIT.EDU Mon Feb 23 13:07:18 2004 From: chipd at MIT.EDU (Carl Dietrich) Date: Mon, 23 Feb 2004 13:07:18 -0500 Subject: [Unified-mailman] Lab space Message-ID: Students, Please take note of the new constraints on lab space, and move your dragonfly models accordingly.

Message-ID: http://www.latimes.com/news/nationworld/nation/la-022304copter_lat,1,2896519 .story?coll=la-home-headlines After $8 Billion, Pentagon Shelves Helicopter By Esther Schrader 2:50 PM PST, February 23, 2004 WASHINGTON ? In a sign that the Pentagon is beginning to feel the budgetary heat, the Army today canceled its Comanche helicopter program, bringing an end to the development of a craft that had been 21 years and $8 billion dollars in the making. The cancellation is one of the biggest in Army history. And unlike the landscape less than two years ago, when Secretary of Defense Donald H. Rumsfeld ordered the Army's $11-billion Crusader artillery system canceled over the protests of senior Army officials, this time the Army decided to take the bullet. The Army had little choice, senior officials of the service said. The RAH-66 Comanche, widely derided as a Cold War-era design with little utility in today's battles, was uniquely vulnerable to an argument made repeatedly by Rumsfeld: that bloated, big-ticket projects conceived during another era are putting Pentagon efforts to modernize at risk. When the Comanche was conceived in 1983, the Army was eager for a lightweight, stealthy reconnaissance helicopter that would be able to move ahead of large tank formations to gather and distribute intelligence and attack enemy formations. But since that day, the Pentagon has developed any number of aircraft that can do all that ? among them Blackhawk and Apache helicopters to attack, and unmanned aerial vehicles and satellites to survey. Meanwhile, the Comanche program encountered one technical setback after another. It was overhauled six times as the cost per helicopter grew. And two years ago, Rumsfeld announced that the program, originally slated to cost $47 billion for 1,207 helicopters, would be cut in half. Under that plan, 650 choppers were to be ready for use in 2009.

Discard the one handed out in class last Thursday. A few minor tweaks to the test parameters have been made after we ran the first few teams through the tunnel. Transition/separation detection tests with the acoustic probe have been dropped -- the tunnel is too loud for this to work. The formulas required for data reduction have been changed from what I presented in lecture. We discovered that the load cell axis conventions and the load cell data output are not what I assumed. The new SP3 writeup has all the details, so please follow that.
