Subject: TL-8 Attack Helicopter

	This helicopter is designed by using the design options
	that were presented in TML-316. (volume based body, modern
	gas turbine, increased lift from rotor)
	Compared with current military helicopters, this helicopter 
	is quite small, light and has poor lifting capability.


	TL-8 LHX-95 Attack Helicopter (Light Helicopter eXperimental)

	This helicopter is a light two-man attack helicopter with 
	design features taken from RAH-66 Comanche and Ka-60 Hokum.
	The main features are CMR rotor configuration, retractable 
	missile bay, stabilized autocannon in tilting forward mount, 
	and stealth hull. However the helicopter loses its stealth 
	capability if there is ordinance in the two external 
	hardpoints. 

	General Data

			10 tons maximum take-off weight

	Engineering Data
	Power Plant:	1.257 MW TL-8 gas turbine
	Maximum Speed:	340 km/h (Calculated from real mathematical 
			model. In higher speeds the compressibility of 
			air and supersonic rotortips make flying
			unstabile)
			320 km/h (With full load and 0.5 m3 extra fuel,
			corresponds to the FFS maximum speed for 
			helicopters.)
	Cruising Speed:	240 km/h
	NOE Speed:	120 km/h
	Agility:	4
	Fuel Capacity:	1.508 m3 of HCD (+ 2x1.5 m3 in IWHP)
	Fuel Consum:	0.377 m3/hour (endurance of 4 hours)
	Maint:		2

	Electronics
	Computer:	TL-8 Model Flt Computer
	Commo:		300-km radio, 30-km laser communicator/designator
	Avionics:	TL-8 flight, terrain and navigation aids
	Sensors:	3-km radar (designation capable), 30-km HRT
			sensor, 250 m image intensifier viewer
	ECM/ECCM:	TL-8 stealth (+1 DiffMod vs. radar and HRT)
	Controls:	Computer linked (fly-by-wire)

	Armament
	Offensive:	3cm/97 fully stabilized autocannon, with optic 
			rangefinder and ballistic computer (-2 Diff 
			Mods), 1000 kg (1 m3) retractable missile bay,
			2x1500 kg IWHP (plumbed)
	Defensive:	3x10 decoys
	Ammunition:	500-round magazine for autocannon (full extra 
			magazine weights 339 kg)
			up to 1000 kg missiles in retractable bay
			2x1500 kg of ordinance or fuel in IWHPs

	Accommodations
	Life Support:	Basic
	Crew:		2 (pilot and weapons officer)
	Crew Accom:	2 open crewstations
	Passengers:	None
	Cargo:		0.62 m3 reserved for extra equipment

	Round		ROF	C/B	DamVal	PenVal	Magaz	SRange
	3cm APFSDSDU	16	-	36	15	500	600
	3cm HEAP	16	C1,B7	-	23C	500	600
	3cm KEAP	16	-	36	5	500	600

	Note: damage from the 3cm autocannon is calculated with the
	same formula as for guns.
