Hello all,

  

 I'm trying to fully understand the nosedrop problem.  I had assumed the problem was nose drop after touchdown, but it sounds like it's a nose drop in the flare but prior to touchdown.  Is that right?  

  

 Thanks,

 Scott

Hi Scott, et al, 

     I suspect those who experienced this problem are no longer active on     the List.  Rich might remember.

Vortex generators on the elevator seem to fix mine.

 Hello Scott, You wrote: "I'm trying to  fully understand the nosedrop problem."

  

 There are two nose drop problems in landing the KIS TR-1. They  are:

  

 A) Difficulty in holding the nose wheel off the landing  surface after a normal rate of descent main landing gear touchdown. This is not,  in my opinion, a safety problem, but rather one of annoyance to those pilots who  desire to use aerodynamic braking from the instant of main landing gear  touchdown until they want to lower the nose wheel or until the nose  wheel can no longer be held off the landing surface as a result of slowing speed  during landing roll out.

  

 B) A sudden pitch down of the nose during the landing flare  while still airborne that catches the pilot by surprise and can cause a very  harsh touchdown. If the nose wheel does not contact the landing surface at the  same time as the main landing gear in this harsh initial contact it  will slam down a fraction of a second later as a result of nose down  rotation about the main landing gear contact point.

  

 History bears out that this harsh touchdown can  indeed result in aircraft damage and, potentially, injury to occupants  depending upon the distance fallen.

  

 I think that it is important to understand the difference  between A and B as the discussion proceeds.

Same with the TR-4. Much better elevator authority and landings at low

air speeds with my VG's.

Galin & Randy,



Would you mind sharing pictures of your vortex generators on the elevator?

It would be useful to know in which position the VGs have been found to be effective.



Regards,

             Alfred

 It would appear from both your photograph and your words  "..front of the hinge line.." that your vortex generators are actually placed on  the bottom surface of the horizontal stabilizer and not on the bottom surface of  the elevator.

Ok, I did a search for "vortex generator" on the KIS list and it brought up a whole host of past messages on this same subject which made good and informative reading.
