Nose Layout Notes

Upper Shelf - Vibration Isolated (Lord 150APL Series Mounts) 1/8 7075 T6

Lower Shelf - Vibration Isolated (Lord 150APL Series Mounts) 1/8 7075 T6

CM3, HMR 3000 require Hard Mounting Also directly mounted: GPS Antenna,

Microspectrometer Lenses, K&Z Pyrometers-All to Top or Bottom Skin of Nose

Modification Additional Notes

Upper Shelf reinforced with fiberglass where its bonded to nose fiberglass shell

Old Gimbal Hole: Glassed & reinforced with Aeromat; same as existing glass work

Weight & Balance

Nose before Modification = 4.625 lbs. Modifications plus Instruments = 42.575 lbs Total Estimated Payload Nose = 47.2 lbs Estimated CG of Nose at Station 91 Rear of Nose is Station 100
