Telemetry Experts – 51 Aero

Measurements, More Speed and other Reno Air Race Insights

Against a perfect blue sky, we watched 3 Thunder Mustangs racing in the 2016 Reno Air Race Sport Class Gold heat last Sunday.  All planes flew well with John Parker in Blue Thunder II coming in 2nd place with a speed of 371 mph.  Unfortunately, our fun was momentarily interrupted just after the Gold race ended.  A problem occurred with Blue Thunder II and John had to make an emergency landing on Runway 14.  John, the experienced race pilot he is, walked away unharmed and is determined to fix the airplane, even improve it for next year.

All 3 Thunder Mustangs (Blue Thunder II, Clas Thunder, and Swiss Thunder) running our 51 Aero Flight N’ Sight real-time telemetry had a good showing and displayed solid flying throughout the week.  All 3 planes will be back racing next year – with enhancements so watch out for that!

Thank you to all who came by to see our “Real-time Dyno Concept Demo”.  Using the TECAT wireless torque sensor we are gathering torque measurements to display and to show horsepower in our Flight N’ Sight telemetry trending software.  We plan to implement this capability to optimize engine parameters, possibly making individual cylinder adjustments.  This new feature will be available in our Flight N’ Sight system for racers or planes where high performance is a priority.

Innovation abounds in this crowd! Fred had some engaging discussions around the demo with premier engine builders, dynamic racers and imaginative airplane geeks.  Here are a few of the bold ideas that resonated with us that we’d like to share:

  1. In addition to measuring horsepower, an idea is to measure thrust. Measuring thrust is a true aircraft performance parameter of horsepower and prop efficiency.  Imagine knowing the RPM setting that gives you max power.
  2. Using the torque signature, detect detonation.  Use this data to adjust overall ignition timing or by individual cylinder to avoid excessive engine stress.
  3. In-flight cockpit displays for torque and horsepower to allow a pilot to manually adjust the mixture to get more speed and better performance in real-time.  Plus, it is an additional safety parameter if an engine problem occurs.

Looking forward to updating our engineering progress and exchanging more ideas with you at the next aviation gathering!

51 Aero works with air racers, warbirds, small business airplanes, and high performance experimentals to provide customized flight data trending and analysis to detect and diagnosis problems in minutes so that you can get back to your business of flying faster.  If you or someone you know would like to discover how our telemetry system can dramatically advance your flying, give us a call.

2016 Sport Gold Champion Jeff LaVelle

By | News

The Super Glasair III was back this year and Jeff LaVelle picked up where he left off, winning back the Sport Gold Championship with a best speed of 403.411 mph!  The well proven design seemed stable all week with very little action in the pits.  On Sunday Jeff only ran what he needed to stay in front of John Parker, finishing the race with an average race speed of 383.397 mph.  Congrats Jeff!

Cross Country – In a race airplane

Cross Country - In a race airplane...

Racers,
This is Tom McNerney, your secretary of the Sport Class and fellow racer of #55 Unleashed.  I was planning my trip west to Stead and remembered something I put together a few years ago that I thought would be worth sharing.  At this point you may have enough time to round up some of these items before your own trip.

Just after the 2015 Pylon Racing Seminar, Andy and Jackie Findlay (Race #30) and I had planned to meet at my home airport so they could overnight ‘One Moment’ in a hangar.  It is a convenient half way stop for them back to the east coast.  We made our plans and I departed as much in front of them as I could to hopefully give myself a small head start, as obviously they would be making up ground on me pretty quickly.  At a fuel stop somewhere in Wyoming, I was writing a dirty joke on a sticky note that I thought Andy might find on the fuel pump when he stopped, when all of a sudden my phone started blowing up.  Turns out Andy and Jackie had their now famous engine failure and prop departure, followed by a successful dead stick landing in Wendover Utah.  That really got me thinking about some of the terrain I had just flown over, and what I would have done had my engine or prop failed.  Just East of Salt Lake City is not a friendly place for a small wing Lancair, let’s be honest.  So, I figured I should plan ahead next time.

In my local EAA chapter there is a retired Army colonel who was partly responsible for equipping personal for emergencies.  Perfect!  We sat down and talked a lot about what would be really handy to have, while keeping the kit reasonably sized and lightweight.  For the record, I knew very little about this subject.  Also, camping isn’t really my thing, but if you enjoy that stuff, you’re already ahead of me.  On to the kit.

We agreed the most important thing would be a PLB or Personal Locator Beacon.  I went with the ACR Resqlink Plus.  It is reasonably priced, super small, and broadcasts on 121.5, 406 and GPS enabled.  Basically the best ELT you can get in the palm of your hand.  That would be the first thing to help my situation in the event of an off airport landing.

The rest is pretty obvious, so I’ll just list the things I have with some order of importance, and a few side notes.

  • Folding Knife (super sharp, found it at Home Depot)
  • Emergency Whistle (yelling would really get old..)
  • Celox (blood clotting powder, also at Target)
  • Burn Gel (guess – Target)
  • Emergency Blanket (I’m a Target guy..)
  • Signal Flag Thingy (the really bright orange towel)
  • Drinking Water Packets
  • Matches and a striker
  • Giant yellow trash bag (you never know, and it’s totally unnatural yellow)
  • Para Cord (you may want to build a hobo tent with your trash bag – Target)

One of the last things was rather interesting.  My Army friend got me a tourniquet that can be used with only one hand.  Looking at the reality of having to use a tourniquet, it seems rather likely that you might only have one hand to use it.  Something to think about for sure.

Another reality that was brought up was this: What if your hanging upside down?  You open up your bag of life saving goodies and they all drop away from your reach..  Bummer..  The important items that you may need rather quickly, say the knife, are tied to your bag with string.  So, even hanging upside down, you can still reel in your knife and get to work.  I thought that was really clever.  Speaking of the bag.

What do you put all this in?  I fit all of the items in the photo above in a satchel.  Some may call it a fanny pack, but I call it a satchel, because Indiana Jones wears one.  (that is a Hangover movie reference for all you old people)  The funny thing about this fanny pack, I mean satchel, is Target doesn’t have any.  Guess they aren’t exactly in-style anymore.  Wal-Mart though?  Good to go.  Moral of the story is that my satchel is attached to me in the airplane.  Forget everything else.  If I jump, climb, fall, run, however I get out of the airplane, that bag is coming with me.  If I leave it behind for some reason, what was the point in packing it to begin with?

Anyway, take this advice for what it is, a reality check that what we do as air race pilots tests our machines well up into the yellow arc of all parameters.  The likelihood of a failure is undoubtedly increased, even for your flight home after the races.  Nobody will be criticized for planning for the unplanned.

Tom McNerney – Secretary
Unleashed #55

P.S. I wish you all the slowest qualification times ever so my 4 cylinders of fury shames you all. 🙂

Sport Gold L-39 Pace

By | News

The Sport Class has been growing at such an incredible rate recently, not only in the size of the class but the speed of the top contenders, causing the class to change the way we start the Gold race.  First, some more information about how some of the Gold racers work.

An experimental aircraft that is capable of 400 mph takes some fine tuning to say the least.  Slang we use for that is called twizzling.  Generally it consists of winding up a huge engine to create monster power levels, while flying formation, down the start chute of the race.  These big engines take more than just throttle to make the power they do.  With so many systems, manifold pressure, rpm, fuel flow, ADI flow, coolant spray bars, etc etc, you get pretty busy in the cockpit.  This phase of the flight is compounded when you have to start from a low power setting, i.e. lower airspeed.  The huge change in power levels cause massive changes in settings, something that is very hard to do in line abreast formation.  The solution for this is actually very simple: Start the races at a higher power setting, where the engine is already ‘happy’.  In the end that is much safer for pilots and engines, but it created a new problem.

The pace plane that the Sport Class has been using for many years is a Lancair Evolution, a PT-6 powered pressurized 4 seat kit aircraft.  A leader in its class, but not quite fast enough for the Gold race.  When you think about it, the Gold racers are now some of the fastest piston engine propeller aircraft that exist.  The only way to have a safe pace aircraft is to either use an actual race aircraft, or..  use a jet!

With this beautiful example of an L-39 we can easily set a proper chute speed where the Gold racers can be up at a power level where the engine wants to be, making a much safer and competitive race start.
