Sikorsky S-70C 'Blackhawk'
Type:
Twin-turbine utility helicopter
Origin:
USA
Similar aircraft:
S-76 Seahawk
Rotor system:
Four-blade main rotor. Sikorsky SC-1095 blade section, with thickness-chord ratio of 9.5%. Middle section has leading-edge droop and trailing edge tab to overcome vortex impingement from preceding blade in cruising flight. Blade twist 18. Blade tips swept back 20. Each blade consist of hollow oval titanium spar, Nomex honeycomb core, graphite trailing-edge and root, covered with glassfiber/epoxy, with glass fiber leading-edge counterweight, titanium leading-edge sheath and Kevlar tip. Blades are tolerant to 23 mm gunfire damage, and are pressurized and equipped with gauges providing fail-safe confirmation of blade structural integrity. Electrically heated de-icing mat in leading-edge of each blade of both main and tail rotors. Forged titanium one-piece rotor head with C/R Industries elastomeric bearings which require no lubrication, reducing rotor head maintenance by 60%. Bifilar self-tuning vibration absorber on rotor head. Manual blade folding. Canting of tail rotor (20 to port) increases vertical lift and allows greater CG travel. 'Cross beam' of four-blade tail rotor of composite materials, eliminating all rotor head bearings.
Rotor drive:
Conventional transmission system with both turbines driving through freewheeling units to main gearbox. This is of modular construction to simplify maintenance. Transmission can operate for 30 min following total oil loss. Intermediate and tail rotor gearboxes oil lubricated. Main rotor shaft can be lowered for storage or air transport.
Fuselage:
Conventional semi-monocoque light alloy structure, designed to retain 85% of its passengers and a flight deck space in a vertical crash at 11.5 m/sec (38 fps), a lateral crash at 12.2 m/sec (40 fps). It can also withstand a combined force of 20g forward and 10g downward. Composite materials including glassfiber and Kevlar are used for the cockpit, doors, canopy, fairings and engine cowlings. Glassfiber Nomex floors.
Tail unit: Pylon structure with port-canted tail rotor mounted on starboard side. Tail pylon design permits normal forward flight and roll-on landing if tail rotor is destroyed. Large variable incidence tailplane has a control system which senses airspeed, collective lever position, pitch attitude rate, and lateral acceleration. Tailplane is set at about +34 incidence in the hover, and -6 for autorotation. Tailplane moved by dual electric actuators, with manual backup. Tailboom folds (to starboard) immediately forward of tail pylon for transport and storage.
Landing gear:
Non-retractable tailwheel type with single wheel on each unit. Energy absorbing main gear with a tailwheel which gives protection for the tail rotor in taxiing over rough terrain or during a high-flare landing. Axle assembly and main gear oleo shock absorbers by General Mechatronics. Mainwheel tire size 26 x 10.00-11, pressure 8.96-9.65 bars (130-140 psi); tailwheel tire size 15 x 6.00-6, pressure 6.21-6.55 bars (90-95 psi).
Accommodation:
Flight deck of two, with provision for 12 passengers in standard cabin configuration and up to 19 passengers in high density layout. Forward hinged doors on each side of flight deck for access to cockpit area. External cargo hook, having a 3,630 kg (8,000 lb) lift capacity, enables the S-70C to transport a 105 mm howitzer, its crew of five and 50 rounds of ammunition. Cabin mounted rescue hoist of 272 kg (600 lb) capacity and aero-medical evacuation kit optional. Large rearward sliding door on each side of the fuselage for rapid entry and exit.
Powerplant:
Two 1,625 shp (1,212 kW) General Electric CT7-2C or 1,723 shp (1,285 kW) CT7-2D turboshafts. Combined transmission rating (continuous) 3,130 shp (2,334 kW). Maximum fuel capacity 1,370 liters (362 US gallons; 301 Imp gallons).
Systems:
Solar 90 hp (67 kW) T-62T-40-1 APU. Garret engine start system. An optional winterization kit provide a second hydraulic accumulator, maintaining engine start capability at low ambient temperatures; Bendix 30/40kVA and 20/30kVA electrical power generators; 17Ah nickel-cadmium battery. Engine fire extinguishing system. Rotor blade de-icing system optional.
Avionics and equipment:
Com equipment comprises E-systems AN/ARC-186 VHF-FM, GTE Sylvania AN/ARC-115 VHF-AM, Magnavox AN/ARC-164 UHF-AM, Collins AN/ARC-186(V) VHF-AM/FM, Bendix AN/APX-100 IFF transponder, Magnavox TSEC/KT-28 voice security set, and intercom. Nav equipment comprises Emerson AN/ARN-89 ADF, Bendix AN/ARN-123(V)1 VOR/marker/beacon/glidescope receiver, Sperry AN/ASN-43 gyrocompass, Singer Kearfott AN/ASN-128 Doppler and Honeywell AN/APN-209(V)2 radar altimeter. Hamilton Standard AFCS with digital three-axis autopilot.
