GORMLEY, Ontario CAN -- Cesaroni Technology Incorporated (CTI) is pleased to announce the development and successful test firing of the first Pro150® "O" class reloadable motor system.

Originally developed for a commercial research contract with blacksky Corporation, the HPR version of this professionally engineered product will set a new standard for the sport rocket industry with design and construction techniques normally only seen in large motor systems.

The first of these motors scheduled for certification firing, the O5100, is the smaller of two systems to be offered, using a three grain set containing 29.2 pounds of propellant. Performance specifications are as follows:

The propellant grains use a combination of traditional center-perforate construction, with tri-form neutralizing slots running the length of the core to boost initial impulse and create a more regressive time-thrust profile. This motor delivers lots of thrust off the pad for safe launch velocities with large heavy vehicles, then gradually regresses to reduce dynamic stresses and lessen the chance of separation at burnout.

The larger four-grain version of this motor will produce total impulse close to the HPR limit of 40,960 Ns, with a similar burn time. Longer burn variants are planned for later release. It was believed that the primary use of these motors will be in extremely large and heavy rockets flying to moderate altitudes and thus this high thrust series was scheduled for the first certification tests and delivery.

These motors will be offered through a limited distribution network, as it is important that they are only purchased and flown by those capable of launching them safely and at appropriate launch sites. CTI will custom anodize the casings in any available color, and will begin accepting pre-orders immediately in order to plan production. Delivery of first articles is scheduled for mid to late summer.

Retail cost for Pro150 motor hardware and reloads kits will be released soon. For more information, visit the website: http://www.pro38.com
