Transcript of Copy of Untitled Prezi
Identify and Track predict and emulate human sense-making Crew: 1
Length: 62 ft 1 in (18.90 m)
Wingspan: 44 ft 6 in (13.56 m)
Wing area: 840 ft² (78.04 m²)
Powerplant: 2 × Pratt & Whitney
F119-PW-100 Pitch Avionics
RWR (Radar warning receiver): 250 nmi (463 km) or more
Radar: 125–150 miles (200–240 km) against 1 m2 (11 sq ft) targets. Guns: 1× 20 mm
Air to air loadout:
6× AIM-120 AMRAAM
2× AIM-9 Sidewinder
Air to ground loadout:
2× AIM-120 AMRAAM and
2× AIM-9 Sidewinder for self-protection, and one of the
Hardpoints: 4× under-wing pylon stations can be fitted to carry 600 U.S. gallon drop tanks or weapons, each with a capacity of 5,000 lb (2,268 kg). The F-22 is designed like the F-117.
Materials can resist very hard conditions
Include weapons and paint improved
Low radar cross section
the radar cross section is the same as "steel marble". Metallic alloys A bit of history... Lockheed spent a lot to research new ways to manufacture titanium for the SR-71. Today 2 main categories of materials :
39% in the F22
1,5% in the F16 Metallic alloys Aluminum
16% in the F22
80% in the F16
Structural components in the F16
Still used but not very much
8% in the F16 Composites F22 : 24 %
F35 : 35 %
F16 : 3 % Great mechanical properties
Lighter than metals
Can't handle strong shocks
Very expensive Composites Carbon fiber Nicalon fiber
(ceramic composite) Carbon Nanotube (SWNT or MWNT)
tubular structure made up of carbon atoms
50 times stronger 10 times lighter than steel
used on the F35 Secret materials RAM : Radar-absorbing material Originally developped for the F117

Distribution of the production F22 Raptor Applications Fight AIR/AIR
Qualities for mission :
Very low stalling speed
Very good maneuverability
Top speed : Mach 1,82 (1,963 km/h) F22 Raptor Radar Cross section What
How F 22 Raptor Cryogenic machining for titanium Cooling the tool at -192°
Increase cutting tools life by 10
Double material-removal rate
No lubrification fluid
Simple carbure tools Titanium machining Difficult to machine alloy change shape during machining
low thermal conductivity
Plastic deformation during machining laser assisted machining Heating the piece in front of the tool (1000°C)
40% productivity gain
cost reduction around $10 per kg
increasing cutting tools life
Management by Lockheed Martin Do what’s right
Perform with excellence.
Lockheed Martin Model is organized into 4 Tiers : Tier 1 : Program Manager
Execution of the entire program : Contract award, Design, Build delivery and Post delivery,...
Tier 2 : Functional Teams
Finance, Chief Engineer, Quality, Operations,...
Tier 3 : Integrated Product Teams
Leads : Weapon System Development, Weapon System Integration,...
Tier 4 : Detailed Product Development = Floor employees
Assemble aircraft, handling,... Management by Lockheed Martin Powerful link between Tiers
Real work in team
