shropshire 0 #1 February 22, 2008 So I've seen a few threads over the years about Highest/longest FreeFall but what about the highest deployed canopy ride... When would the air be thick enough to support a canopy What type/size would it need to be ? How fast would it be going (H & V)? Any ideas? (.)Y(.)

jtval 0 #2 February 22, 2008 Well, I am not an engineer and this is where I'll prove it. I would assume that anywhere within our atmosphere would be able to fly a canopy. you would just lose some of the foward ratio to downward movement as the air is pushed into the cells.My photos My Videos Quote Share this post Link to post Share on other sites
shropshire 0 #3 February 22, 2008 But you'd need enough pressure to fill the canopy (the speed would probably do that - but how high would that speed be and at what altitude?). (.)Y(.)

DougH 270 #5 February 22, 2008 I dunno... but get high enough and you are going to want to figure out how to deploy it very gently. The differential between freefall speeds and deployment is going to be a bitch!

GLIDEANGLE 1 #11 February 22, 2008 Para Flite's Intruder canopy for military operations (High altitude high opening) is advertised with a maximum deployment altitude of 30,000 ft. Their PARIS canopy is advertised with a max depolyment antitude of 25,000 ft. http://paraflite.com/Intruder%20Main%20Canopy.htm http://paraflite.com/PARIS.htm These operations are intended to allow the jumper to exit FAR from the landing point. This allows for a stealthy entry without placing the aircraft near the canopy landing site. From the Para-Flite web site: Given a 25,000 foot exit altitude, an insertion team using the PARIS can travel over 40 kilometers without factoring wind effects. Given favorable wind conditions, the offset can be increased to over 75 kilometers. This increased distance provides additional safety for the aircrew and improved security for the insertion team. I figure the maximum height for canopy flight is pretty high. I also figure that the limiting factors for such flight are NOT the canopy... but keeping a human alive in the cold and low oxygen/pressure environment.The choices we make have consequences, for us & for others!

Erroll 80 #12 February 22, 2008 Quote I also figure that the limiting factors for such flight are NOT the canopy... but keeping a human alive in the cold and low oxygen/pressure environment. One would also expect some kind of specialised 'seating' arrangement. Travelling 40+ kilometers under canopy could play havoc with one's blood circulation.

James.UWE 0 #13 February 22, 2008 Quoteive seen some videos of instructors deploying canopies of students who couldnt get stable at around 12k feet. Assuming that exit altitude is between 12-15k, the instructor isnt really giving the student much chance to get stable is he? Unless they where injured etc?

Andrewwhyte 1 #19 February 22, 2008 If the airfoil is going fast enough it should fly. The only limits I can see are mach and the induced turbulence around that, and the amount of drag, especially parasitic drag caused by the lines and load going that fast.

DBCOOPER 5 #20 February 22, 2008 When I was out at Davis for high altitude jumps a couple of years ago there were some British Military guys that did either hop and pops or static line jumps at 30K,on rounds.Replying to: Re: Stall On Jump Run Emergency Procedure? by billvon If the plane is unrecoverable then exiting is a very very good idea.

BillyVance 35 #25 February 22, 2008 Not that it has any relevance here but the base group of the CRW world record 100 way were jumping out at 20,000 feet, maybe a bit higher. That might be the highest load of hop and pops ever.
