Hello I want edit the engine data of the E-2 Hawkeye to immitate a Yak-144. In other words I want to add more power to the engines since the D-27 has 10,290 kW vs 3,800 kW of the T56-A-427.

 

What does the varibales mean and which units are used?

 

 

The engine data looks as follow of the E-2 in the LUA file:

engine = 
	{
		Nmg	=	60.00001,--67.5,
		MinRUD	=	0,
		MaxRUD	=	1,
		MaksRUD	=	1,
		ForsRUD	=	1,
		type	=	"TurboProp",
		hMaxEng	=	19,
		dcx_eng	=	0.0144,
		cemax	=	1.24,
		cefor	=	2.56,
		dpdh_m	=	3000,
		dpdh_f	=	3000,
		table_data = 
		{
			[1] = 	{0,	75395.9,	75395.9},
			[2] = 	{0.1,	74143.8,	74143.8},
			[3] = 	{0.2,	61765.6,	61765.6},
			[4] = 	{0.3,	51900.8,	51900.8},
			[5] = 	{0.4,	43773.3,	43773.3},
			[6] = 	{0.5,	35854.2,	35854.2},
			[7] = 	{0.6,	29229.2,	29229.2},
			[8] = 	{0.7,	24312.3,	24312.3},
			[9] = 	{0.8,	20719.3,	20719.3},
			[10] = 	{0.9,	16500,	16500},
		}, -- end of table_data
	}, -- end of engine

Hi.

 

You can just raise those numbers in table_data. As said, first number is thrust without AB, second is thrust with AB...since it is a turboprop, the numers are equal.

Second thing is, as far as I found out, the numbers in dpdh_m and dpdh_f. They determin how higher/lower altitudes affect the engine power.

But your questions will be mostly answered if you read the "Beginners Guide to DCS World aircraft mods v 0.5.1". There is a section especially talking about the SFM and tuning and everything. Quite informative :-)
