![Page 13: Provider of Near Space Solutions. Tactical Ballooning & Return Vehicles A New Paradigm for Low Cost Near Space Access & Persistence Near Space Corporation](https://reader036.vdocument.in/reader036/viewer/2022081519/56649e915503460f94b96117/html5/thumbnails/13.jpg)
PROBLEM #1: GROUND WINDS > 5 KNOTS
• Ground Wind Problem Linked to Inflation and Launching
• At Low Altitude:
• Relatively Small Gas Bubble• Excess Material • Material Becomes Large Sail• High Potential for Film Damage
• At High Altitude:
• Gas Expands• Material is Fully Deployed• Balloon Moves with the Wind• Low Potential for Film Damage
![Page 14: Provider of Near Space Solutions. Tactical Ballooning & Return Vehicles A New Paradigm for Low Cost Near Space Access & Persistence Near Space Corporation](https://reader036.vdocument.in/reader036/viewer/2022081519/56649e915503460f94b96117/html5/thumbnails/14.jpg)
• General Approach: View Wind as the Enemy
• Common Approach: Enclose Balloon in a Protective Bag Before Launch
• Prevents Balloon Damage from Ground Contact
