Curt von Delius Sets New J and M-Class Altitude Records With AeroTech Reloads at XPRS 2008 Launch
Curt von Delius, using a modified version of his record-setting Level 3 airframe, crushed his previous M-class altitude record of 37,762 feet by flying it to a GPS verified altitude of 45,328 feet AGL on September 19th 2008 and also set a new J-class altitude record of 19,758 feet on September 21st 2008, during the XPRS launch in Nevadas Black Rock Desert. The altitudes were recently certified by the Tripoli Contest and Records Committee.
Scorched from aerodynamic heating after reaching almost 2,000 miles per hour, von Delius MMAX flight used an 8,060 newton-second, Kosdon by AeroTech Animal-Compatible (KBA A-C) M1450W reload kit (AeroTech P/N K13145P, $300.00 MSRP) that generates a peak thrust of 480 pounds during a burn time of 5.46 seconds. The rocket pulled 24 Gs and the time to apogee was 46 seconds, with the vehicle coasting for nearly 40 seconds after motor burnout.
The airframe was separated at apogee using black powder charges and was recovered with custom hybrid and Kevlar parachutes, of von Delius own design and construction. A Beeline GPS was used to verify the maximum altitude and provide tracking during the over 5 minute descent (launch photo by Steve Wigfield).
Less than 20 days earlier at the AeroPac Aeronaut Launch, also in Nevadas Black Rock Desert, von Delius clinched the previous Tripoli M-class altitude record by achieving a GPS verified altitude of 37,762 feet. Curt is also the holder of the 'L'-class record of 31,316 feet.
Von Delius high-altitude design was constructed with lightweight carbon fiber composites and weighs 56 oz. without the motor. The modified design now measures 59.77 in length and 3.13 in diameter with a flying weight of less than 20 pounds. After ignition, the vehicle reached 71 miles per hour before exiting the custom-built 8-foot aluminum launch tower.
We had excellent conditions for this launch with mild surface and aloft winds. It all seemed to come together on this flight with an arrow straight boost and all systems and recovery working flawlessly said von Delius. AeroTech/RCS President Gary Rosenfield added, "We are thrilled that Curt chose to use AeroTech products for his record attempts. The M1450W reload especially represents a convergence of performance parameters that are ideally suited for this kind of effort."
Von Delius Sets New 'J'-Class Record of 19,758 Feet
Two days after setting the new M-class altitude record of 45,328 feet, also at the XPRS launch, Curt von Delius improved on his existing 'J'-class record of 19,240 feet by flying his state-of-the-art carbon JMAX, setting the new Tripoli single motor record of 19,758 feet.
Flying on an RMS-38/1080 motor loaded with an AeroTech J570W reload kit (AeroTech P/N 10570M, $80.00 MSRP), von Delius latest JMAX design is his fourth attempt to crack 20,000 feet AGL, and the third time to set a new J-class record using a J570W. A total of three airframes have been built and flown, each improving on the original record design (launch photo by Patrick Wagner).
This flight boosted incredibly straight out of the tower, and the flight and recovery went very smoothly, too bad it didnt clear 20,000 feet said von Delius.
At 29.625 inches long and 44 oz., the all-carbon screamer hit 1,954 miles per hour and pulled 93 Gs for two seconds, coasting for another 28 seconds to apogee. The JMAX was launched from an 8-foot custom aluminum tower and was recovered with a hybrid chute system deployed at apogee, all designed and constructed by von Delius.

In the dictionary under "hard core altitude junkie" it has a photo of Curt von Delius.
