    4. Gantt Chart

    5. Marketing Data Research Interviewed 20 people Questionnaire Analyze the data Compared all the responses Created an average value

    6. Important: combustion, standardization, mechanical assembly, legal to fire Not Important: Gun-like look and feel, personal assembly of electronics

    7. Important: Almost everything we asked Not Important: low noise levels, large recoil, use of other projectiles

    8. Important: price under $50, keep away from youth Not important: Silencer, Strap

    9. Engineering Specs Design Specifications: Total Length: < 5 ft < 1.5 m Barrel Length: 48 in 1.2 m Total Weight: <15 lbs <6.8 kg Avg. Projectile Weight: 0.22 lb 100 g Max. Projectile Range: 200 yards 180 m Max. Seal Pressure: 100 psi 690 kPa

    10. Engineering Specs Preliminary Ballistics Calculations: 180 m range for a 100 g projectile requires: Time of flight of 6 s. Muzzle velocity of 42 m/s. Accelerating force of 73.5 N for entire 1.2 m length Average combustion pressure of 125 kPa Total Projectile Energy at Muzzle: 88.2 J
