Ki-116 Performance

[Laurelix]

Basically a re-designed Ki-84. Its engine was downgraded to 1500hp Ha-112-II and the propeller was changed to a 3 bladed one. Furthermore weight was significantly reduced to not hamper the performance
Loaded Weight of the Ki-84 was 3600kg whilst the loaded Weight of the Ki-116 was 350kg less. The top speed decreased along with its rate of Climb but the Agility increased. For example Ki-84's wing Loading is 171.4kg/m2 whereas Ki-116's is 154.8kg/m2.

General Data:
Empty Weight: 2300kg
Loaded Weight: 3250kg
Wing Area: 21m2
Engine: Ha-112-II
Take Off: 1500hp / 1350hp at 2000m / 1250hp at 6000m
-
Max Speed: (Military / WEP)
Sea Level: 505kph / 535kph
1000m: 530kph / 562kph
2000m: 558kph / 591kph
3000m: 562kph / 596kph
4000m: 565kph / 599kph
5000m: 585kph / 620kph
6000m: 600kph / 610kph
-
Rate of Climb: (Military Power)
Time to 1000m: 1:00
Time to 5000m: 5:53 *

# According to manual
* It's a rough estimate since Ki-100 which was 245kg more heavy with the same engine achieved 6:00 to 5000m rate of Climb
-
Stall Speed: (Sea Level, Level Flight)
Flaps at 0 degrees: 148km/h IAS
Flaps at 15 degrees: 130km/h IAS
Flaps at 30 degrees: 122km/h IAS

Flaps at 0 degrees = Normal (1.46 CL_Max)
Flaps at 15 degrees = Take Off / Combat (1.70 CL_Max)
Flaps at 30 degrees = Landing (1.92 CL_Max)
-
Sustained Turn Time: (360 horizontal turn, No Flaps, WEP)
16 seconds
-
Maximum Safe Dive Limit:
800km/h IAS
-
Firepower:
2x 12.7mm Ho-103 (350 rounds per gun)
2x 20mm Ho-5 (150 rounds per gun)

Hello Laurelix,

It seems from information posted earlier from translated Japanese tests that the Dive Speed Limit should be 750 KPH for a regular Ki-84.
Is there a reason why the dive limits increased with the Ki-116?

Sources for Ki-116 state 800. But the Ki-116 did undergo modifications to the plane so maybe it effected it. But I'm not 100% sure
